Abstract: The increase in concrete structures’ durability is a milestone to improve the sustainability of buildings and infrastructures. In order to ensure a prolonged service life, it is necessary to detect the deterioration of materials by means of monitoring systems aimed at evaluating not only the penetration of aggressive substances into concrete but also the corrosion of carbon-steel reinforcement. Therefore, proper data collection makes it possible to plan suitable restoration works which can be carried out with traditional or innovative techniques and materials. This work focuses on building heritage and it highlights the most recent findings for the conservation and restoration of reinforced concrete structures and masonry buildings.

Classificazione: 1 Contributo su Rivista
Abstract: Digital image correlation (DIC) is a contactless full-field optical technique for measuring displacements that can be potentially used in place of more common linear variable differential transformers (LVDTs) to avoid instrumentation damage during destructive tests. However, despite being already adopted in several fields, its potentialities in testing full-scale masonry walls strengthened with textile reinforcing mortar (TRM) have not been fully investigated yet. In this paper, the results obtained by applying a stereo-DIC technique to compression tests of unstrengthened and TRM-strengthened tuff masonry walls (1.0 x 1.2 x 0.25 m(3)) are reported. Results showed that the presence of helical steel bars used to connect the two TRM layers caused crack localisation to the masonry wall, leading to a reduction of compression strength. Compared with the results obtained with LVDTs, the DIC technique was able to accurately monitor tridimensional displacements and cracking pattern evolution. The potentialities and limits of this technique are finally highlighted.

Abstract: Scanning microwave microscopy (SMM) is a novel metrological tool that advances the quantitative, nanometric, high-frequency, electrical characterization of a broad range of materials of technological importance. In this work, we report an inverted near-field scanning microwave microscopy (iSMM) investigation of a graphene oxide-based epoxy nanocomposite material at a nanoscopic level. The high-resolution spatial mapping of local conductance provides a quantitative analysis of the sample's electrical properties. In particular, the electrical conductivity in the order of ∼10-1 S/m as well as the mapping of the dielectric constant with a value of ∼4.7 ± 0.2 are reported and validated by the full-wave electromagnetic modeling of the tip-sample interaction.

Uniaxial tensile behavior of ultra-high performance fiber-reinforced concrete (uhpfrc): Experiments and modeling
COMPOSITE STRUCTURES
Autore/i: Donnini, J.; Lancioni, G.; Chiappini, G.; Corinaldesi, V.
Classificazione: 1 Contributo su Rivista
Abstract: Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC) is considered a promising material for many structural applications where high strength and high energy absorption capacity are required. The purpose of this work is to study the uniaxial tensile behavior of soft cast (flowable at casting time) UHPFRC by varying the amount of hooked steel fibers (30-mm long) from 0% up to 2.55% by volume. Direct tensile tests have been performed on dog-bone shaped specimens and Digital Image Correlation (DIC) has been used to measure displacements and deformations and to monitor the evolution of cracks. Then, a phase-field model has been implemented in a FE code and numerical simulations have been performed to better understand the effects of different fiber dosages on the mechanical behavior of UHPFRC composites and on their post-elastic evolution. Concrete matrix and fiber reinforcement have been modeled as brittle and elasto-plastic phases of a mixture, whose internal energies are enriched by non-local damage and plasticity contributions. The different failure mechanisms observed in experiments have been reproduced, including the ductile failure experienced by specimens with sufficiently high fiber dosage, which distinguishes for a strain-hardening phase of matrix multi- micro-cracking that anticipates material failure.

TRM reinforced tuff and fired clay brick masonry: Experimental and analytical investigation on their in-plane and out-of-plane behavior
CONSTRUCTION AND BUILDING MATERIALS

Classificazione: 1 Contributo su Rivista
Abstract: The paper presents the results of an experimental campaign aimed at investigating the in-plane and out-of-plane behavior of tuff and fired clay brick masonry panels reinforced by a commercial, not yet tested, Textile Reinforced Mortar (TRM) system. The TRM, consisting of hydraulic lime mortar coupled with a bidirectional glass fabric (total thickness of 30 mm), was applied on both sides of the panels and connected through stainless-steel helical bars. First, a mechanical characterization of the TRM system was carried out, according to recent guidelines (AC434 and CNR-DT215) by means of tensile tests and single-shear bond tests on the two different substrates. Then, the effectiveness of the reinforcement was investigated through uniaxial compression, diagonal compression and three-point bending tests on masonry panels. After that, experimental results were compared to the predictions of recent guidelines and analytical models available in the literature, by using the mechanical parameters obtained from the TRM mechanical characterization. TRM showed to be very effective in increasing the in-plane shear strength of tuff panels, of about 170%, whereas in the case of fired clay brick ones the increase was limited to 33%. Besides, the diagonal compression strength of reinforced specimens seemed to be strongly influenced by the mortar matrix, instead of by the fabric reinforcement, as it usually happens i.e. for Fabric Reinforced Cementitious Matrix (FRCM) systems. Thus, novel simplified analytical formulations to predict the shear strength of reinforced panels by only considering the contribution of the TRM matrix were provided, discussed and compared to current analytical approaches for FRCM systems. As regards the out-of-plane behavior, the TRM system significantly increased the out-of-plane bending strength and ductility of both tuff and fired clay brick panels. The applicability of current analytical approaches, as well as possible amendments, was also investigated. Finally, the compressive behavior of the walls was not substantially modified by the reinforcement, reasonably due to the low axial stiffness of the connectors and, to a minor extent, because they were dry inserted within the masonry and simply folded over the glass fabric.

Classificazione: 1 Contributo su Rivista
Abstract: The use of Fabric-Reinforced Cementitious Matrix (FRCM) systems as externally bonded reinforcement for concrete or masonry structures is, nowadays, a common practice in civil engineering. However, FRCM durability against aggressive environmental conditions is still an open issue. In this paper, the mechanical behavior of a glass FRCM system, after being subjected to saline, alkaline and freeze-thaw cycles, has been investigated. The experimental campaign includes tensile tests on the fabric yarns, compression and flexural tests on the matrix and tensile tests (according to AC434) on FRCM prismatic coupons. The effects of the different environmental exposures on the mechanical properties of both the constituent materials and the composite system have been investigated and discussed. Ion chromatography analysis has also been performed to better understand the damage mechanisms induced by environmental exposures and to evaluate the ions' penetration within the inorganic matrix. Alkaline exposure was shown to be the most detrimental for Alkali-Resistant (AR) glass fiber yarns, causing a reduction in tensile strength of about 25%. However, mechanical properties of the FRCM composite seemed not to be particularly affected by any of the artificial aging environments.

Classificazione: 1 Contributo su Rivista
Abstract: The possibility of producing high-volume fly ash (HVFA) recycled aggregate concrete represents an important step towards the development of sustainable building materials. In fact, there is a growing need to reduce the use of non-renewable natural resources and, at the same time, to valorize industrial by-products, such as fly ash, that would otherwise be sent to the landfill. The present experimental work investigates the physical and mechanical properties of concrete by replacing natural aggregates and cement with recycled aggregates and fly ash, respectively. First, the mechanical properties of four dierent mixtures have been analyzed and compared. Then, the eectiveness of recycled aggregate and fly ash on reducing carbonation and chloride penetration depth has been also evaluated. Finally, the corrosion behavior of the dierent concrete mixtures, reinforced with either bare or galvanized steel plates, has been evaluated. The results obtained show that high-volume fly ash (HVFA) recycled aggregate concrete can be produced without significative reduction in mechanical properties. Furthermore, the addition of high-volume fly ash and the total replacement of natural aggregates with recycled ones did not modify the corrosion behavior of embedded bare and galvanized steel reinforcement.

Classificazione: 2 Contributo in Volume
Abstract: The use of Textile Reinforced Mortar (TRM) systems represent a valid alternative to traditional strengthening techniques, to improve mechanical strength and seismic performance of masonry buildings. Their effectiveness has been validated by several studies [1-4]. However, the TRM contribution in the mechanical behavior of masonry walls, subjected to simple compression, has not yet been fully investigated. In this study, an experimental campaign with the objective of studying the efficiency of TRM systems, applied to clay brick masonry panels, is presented. Compression tests were conducted on clay brick masonry panels with dimensions of 250x1000x1200 mm3 . Glass fiber bidirectional fabrics were applied on both sides of the panels, coupled with lime-based mortar, and connected with stainless steel helical connectors. The total thickness of the reinforcement system is 30 mm. The effect of the TRM reinforcement on the mechanical behavior of the panel is analyzed and experimental results are compared with those of unreinforced panels in terms of ultimate strength and failure modes.

Classificazione: 1 Contributo su Rivista
Abstract: The use of new methods to strengthen and rehabilitate existing concrete and masonry structures is one of the challenges that the engineering community is facing in recent years. In this field, composite materials are acquiring more and more success, due to lower invasiveness and ease of application if compared to more traditional systems (e.g. steel plates or reinforced concrete jacketing). This work, based on experimental investigations, aims to propose a comparison between three different methods as possible strengthening solutions for existing concrete elements. Twenty compression tests were conducted on reduced scale concrete columns, realized by using a low performance concrete, in order to reproduce the poor mechanical properties of most existing structures. Two of them were left unconfined, while the other ones were reinforced by using Fiber Reinforced Polymer (FRP), Fiber Reinforced Cementitious Matrix (FRCM) or High Performance Mortar (HPM) systems. The effectiveness of the different strengthening techniques and the main differences in terms of structural response were investigated. Experimental results were then compared with predictions deriving from guidelines and theoretical models from the literature.

Abstract: Already from the beginning, 50 years ago, the first nucleus of researchers establishing the research group, was convinced that the construction sector was the best option for the valorization of industrial by-products as “secondary raw materials”. In fact, this sector is probably the largest consumer of resources and the largest waste generator, consequently it has huge environmental impact. On the other hand, construction materials affect the performance of buildings with respect to safety, health, environmental performance and energy efficiency. Manufacturing of construction products using alternative raw materials; recycling to manage construction and demolition waste; durability and environmental compatibility of materials: all these were the different and challenging fields of research that the group has faced in a continuous effort of innovation and cooperation at national and international level. The focus of the group was already perfectly in line with what is now called “Circular Economy”, which at present is considered a revolution in the way of human economic development. We are sure the group thus contributed to this revolution even before the term was in current use. We feel ready for the next 50.

Abstract: The total distributed strain produced during a vacuum-assisted resin infusion moulding composite manufacture process is measured in real time by using optical fibre sensors embedded in three different layers of a thin 5-harness satin weave flat plate cured with low-viscosity epoxy resin/cycloaliphatic polyamine epoxy resin polymer matrix. We present and discuss the chemical reaction of the epoxy resin polymer matrix adhesive to show that under manufacturing conditions, well below the glass transition point, substrates gradually come into contact with and become covered with epoxy resin polymer matrix strongly bonded to their surfaces. The fluid dynamics of the reaction system under such conditions reduces to a Cauchy equilibrium found in stressed solids, which leads to a strength of materials argument to show that the embedded, distributed optical fibres can accurately measure the motion of the surrounding epoxy resin polymer matrix before the gel point. The same argument is applied to the embedded 5-harness satin carbon fibre weave and leads immediately to an extension of the composite laminate theory for the thermodynamic liquid phase before the glass transition temperature. The predictions of the modified composite laminate theory framework are found to be consistent with experiment.

Mechanical, electrical and self-sensing properties of cementitious mortars containing short carbon fibers
JOURNAL OF BUILDING ENGINEERING
Autore/i: Donnini, Jacopo; Bellezze, Tiziano; Corinaldesi, Valeria
Classificazione: 1 Contributo su Rivista
Abstract: This paper is aimed at exploring mechanical, electrical and self-sensing properties of cement-based mortars through the addition of short carbon fibers, at different dosages (2%, 3%, 4% by weight of cement). Compression and bending tests on carbon fiber reinforced mortars (CFRM) were performed. The addition of carbon fibers showed to enhance the mortars’ flexural strength by increasing the fibers content, while no improvement was found in the compressive strength. Electrical resistivity of the CFRM, at different days of curing, was evaluated by AC impedance measurements, using two stainless steel wire meshes as electrodes. The electrical resistivity decreased with time, until reaching a constant value after about 60 days of curing. Carbon fibers were able to drastically reduce the mortar resistivity, up to values below 150 Ω cm. The effect of fibers dosage on the ability of the mortar to change its electrical resistivity when subjected to different stress states was also studied. The specimens were gradually loaded up to 50–60% of the maximum compressive strength, carrying out two loading/unloading cycles, while resistivity was measured using a conductivity meter. Depending on the fibers dosage and stress state within the material, CFRM resistivity changed with significant variations.

Abstract: The total substitution by volume of natural coarse calcareous aggregate by coarse recycled brick aggregate (RBA) and coarse recycled concrete aggregate (RCA) has been investigated to produce more sustainable and environment-friendly mortars. Aggregates were also partially substituted by their fines at 12.5% by volume. Mortars have been tested in terms of mechanical, microstructural, and durability properties. Results show that it is feasible to replace a natural calcareous aggregate entirely by recycled aggregates. In particular, the obtained mortars, even if more porous and more prone to the water capillary absorption than that manufactured with natural aggregates, result in less stiffness and thus are less subjected to crack formation, more permeable to water vapour, and less susceptible to sulphate attack.

Classificazione: 1 Contributo su Rivista
Abstract: The challenging and innovative idea of realizing a table totally made of fiber-reinforced concrete is explored through an interdisciplinary research activity, where contributions coming from different fields (design, material science, experimental testing, numerical modeling) are combined. The paper describes the different phases of the study, starting from the design of the table, moving through the development of a purpose-made high-performance fiber-reinforced concrete and the mechanical characterization via experimental testing, and concluding with numerical modeling. Numerical results are determined by implementing a damage plasticity constitutive model in a finite element code. The mechanical response of the table has been analyzed for different loading and boundary conditions, and an exhaustive and complete picture of the possible failure mechanisms has been drawn. Simulations have clearly described the different stress-softening processes of damage evolution and plastic strains localization, pointing out the vulnerable parts of the table. Finally, strategies for improving the table mechanical performances are discussed.

Abstract: The use of both cold asphalt and cold recycled asphalt mixtures produced with bitumen emulsion is constantly increasing. The failure properties of these low-energy materials are normally improved by using mineral additions or active fillers. These additions are a key component of the bituminous mortar, which binds the coarse aggregate fraction of the mixture. The objective of the present study is to investigate the evolution of the failure properties bitumen-emulsion mortars obtained by using three different types of additions: Portland cement (active filler), hydrated lime and calcium carbonate (inactive filler). The mortars were prepared with standard sand and a fixed bitumen/addition rate. Cylindrical samples were compacted with a shear gyratory compactor, the selected procedure also allowed evaluating the effect of the different additions and water content on workability. The indirect tensile strengths were measured after 7, 14, 28 and 100 days of curing in two conditions: sealed (i.e. no evaporation) and unsealed, at 50% relative humidity. Each bituminous mortars was also characterized in terms of low temperature fracture resistance. Results showed the influence of the mineral additions on the emulsion breaking and the different curing conditions allowed highlighting the impact of both evaporation and cement hydration on strength and stiffness evolution.

Reuse of recycled glass in mortar manufacturing
EUROPEAN JOURNAL OF ENVIRONMENTAL AND CIVIL ENGINEERING
Autore/i: Corinaldesi, Valeria; Nardinocchi, Alessandro; Donnini, Jacopo
Classificazione: 1 Contributo su Rivista
Abstract: This work is aimed at studying the possibility of reusing waste glass from crushed containers as aggregate for preparing mortars. At present, this kind of reuse is still not common due to the risk of alkali–silica reaction (ASR) between alkalis of the cement and silica of the waste glass. This expansive reaction can cause great problems of cracking and, consequently, it can be extremely deleterious for the mortar durability. The influence of both size and colour of recycled glass coming from crushed containers on the durability of mortars is studied. The attention is focused on both mechanical behaviour, investigated by means of bending and compression tests, as well as durability, studied by means of accelerated tests for evaluating the tendency to expand under alkaline environment due to ASR. Several mortars are prepared by replacing at different rate the quartz sand with coarse glass cullet of different colours: clear (i.e. uncoloured), green and amber. Then, pulverised clear glass is added to the mortar mixtures, also in the presence of class F fly ash. Results obtained show that by using both green and amber glass cullet the mortars are stable, as well as by using powder glass, which also shows a significant pozzolanic effect. On the other hand, considerable expansion due to ASR is detected by using clear glass cullet.

Abstract: In this work, the influence of different kinds of fibres on Fibre-reinforced concrete (FRC) cracking behaviour is examined. Several FRC mixtures are designed, in which cement is partially replaced at 20% by weight of cement by a biomass ash coming from paper mill sludge incineration. These FRCs are prepared by alternatively using steel fibres, polypropilene macro-fibres, glass macro-fibres, as well as hybrid or bicomponent synthetic fibres. The dosage of fibres is always equal to .55% by concrete mixing volume. As reference, also a mixture with the same mixture proportions but without fibre reinforcement is prepared and tested. Ring test according to ASTM C 1581-04 and free shrinkage test are carried out in the same exposure conditions: 21 °C and 50% relative humidity. Moreover, compressive and tensile strengths of FRCs, as well as their elastic modulus, are evaluated on cubic specimens up to 28 days of curing, and, in particular, also at the time of ring cracking. In this way, other important information could be extrapolated by introducing these experimental data in suitable numerical model of the ring concrete specimens available in the literature. This procedure enables to study the influence of the kind of fibres on the potential for early-age cracking of concrete, as well as to identify the effect of tensile creep on concrete cracking. Results obtained show the effectiveness of the randomly dispersed fibres in counteracting the early cracking of FRC.

Abstract: Electromagnetic shielding and propagation in concrete structures are getting more and more interest in radiation hazard problems and wireless communications. The protection of sensitive environment is nowadays carried out by appropriate shielding room made of metallic walls. Even if effective they are heavy structures not adequate for the installation over existing building walls. The using of concrete composites filled by conductive elements represents a valid alternative to metallic shielded room since they can be adopted to directly build up the building walls and/or to easily plaster existing walls

Abstract: This work studies with the influence of recycled coarse aggregates features on the mechanical properties of structural concrete. Recycled concrete is characterised by replacing different percentages of natural coarse aggregate with recycled coarse aggregate (0, 20, 50 and 100%) and two different water-to-cement ratios .50 and .65. The experimental program was carried out at the two laboratories: one at the University of A Coruña and another at the Università Politecnica delle Marche (Italy). For said purpose, two different recycled aggregates were used, with different water absorptions and compositions. Results obtained allowed the authors to establish different mechanical behaviour of recycled concrete (compressive strength, tensile splitting strength and modulus of elasticity) due to different replacement percentages and characteristics of the recycled aggregates.

Classificazione: 1 Contributo su Rivista
Abstract: In this work several fibre reinforced cement-based composites (FRCCs) as well as ultra high performance concretes (UHPCs) were studied, in which CaO-based expansive agent was added in order to help in reducing the risk of cracking induced by drying shrinkage. Three different kinds of metallic reinforcing fibres were tested: flat (and flexible) steel-alloy fibres, and brass-coated either hooked or straight steel fibres. All the mixtures were characterised at both fresh and hardened state, by measuring fresh consistency, compressive and flexural strength, as well as length changes under drying shrinkage test. Moreover, FRCC microstructure was investigated by means of Mercury Intrusion Porosimetry (MIP) and Scanning Electron Microscope (SEM) observations. The effect on mechanical performance of a thermal pre-treatment at 80 °C for the first 24 h of curing after casting was also evaluated. Results obtained confirmed the effectiveness of CaO addition on material stability under drying shrinkage; moreover, it seems to produce a beneficial effect on flexural strength if used with brass-coated fibres. The reason of this synergy probably lies in the formation of calcium-hydroxy-zincate crystals at the interface between fibres and surrounding cement paste (phenomenon promoted by dezincification of brass in alkaline environment), able to significantly improve the quality of the interface fibre–matrix by increasing adhesion.
