The compressive strength and impact-abrasion resistance were used for the estimation of engineering properties while the water absorption performance, surface electricity resistance, and rapid chloride penetration resistance were used for estimation of durability. Experimental results showed that a sole addition of SF increased the compressive strengths but decreased the abrasion-impact resistances of modified FRCs, which was just opposite to the influence of a sole addition of PR. A sole addition of either the SF or PR could moderately improve the durability of modified FRCs, respectively. However, due to the beneficial effect of the complementary interaction between SF and the optimal amount of PR, the mechanical properties and durability of modified FRCs seemed to become significantly improved.</p> H-A.

In this study, a hemp mesh coated with epoxy was manufactured and combined with a cementitious matrix to strengthen a concrete beam. This beam was subjected to bending cyclic loading tests and a nondestructive modal analysis test. The modal analysis was performed to determine the dynamic elastic properties of the beam under pre-cracking, post-cracking, and strengthened conditions. The beam stiffness increased following strengthening with hemp-FRCM. The results of the experimental cyclic loading test showed that the hemp-FRCM system improved the load-bearing capacity of the beam at the service limit state by 42%. Analytical and numerical models were adjusted and validated using the experimental results, and both proved to be effective calculation tools. The models accurately reproduced the behaviour of the FRCM-strengthened concrete beam if the strengthening connection could prevent sliding and mortar debonding failures.</p> L. Mercedes, V.

The results showed that CW improved the uniaxial tensile stiffness, strength, peak strain, and toughness of the steel-PVA hybrid fiber-reinforced cementitious material. The CW not only played a role in the small deformation stage but also improved the load holding capacity and toughness of the hybrid fiber-reinforced cementitious material during the large deformation stage. Computational models to assess the uniaxial tensile strength and toughness of the MSFRCM were established. Microstructure observations showed that the steel and PVA fibers formed a weak interfacial transition zone (ITZ) due to the “wall effect.” The CW effectively optimized the structure of the ITZ of the steel and PVA fibers through physical and chemical effects, such as filling, bridging, improving Ca(OH)<sub>2</sub>&nbsp;orientation, and chemical effects. The steel fibers, PVA fibers, and CW in the MSFRCM bridged cracks at the macro, mesoscopic, and microscopic levels, respectively. As a result, we observed a fiber chain effect that improved the positive hybrid effect between the multi-scale fibers.</p> L. Li, M. Cao, Z. Li, W. Zhang, D. Shi, K.

Compressive properties of PVA-SHCC and MsHySHCC were evaluated experimentally. The results indicate that the designed MsHySHCC had a better compressive performance than that of PVA-SHCC. Moderately partially substituted PVA fibers by steela fiber and CaCO<sub>3</sub>&nbsp;whisker enhanced the compressive parameters, however, further substitution of PVA fibers by increasing the content of CaCO<sub>3</sub>&nbsp;whisker didn’t bring a higher promotion. Two kinds of semi-theoretical compression constitutive models were developed from the perspective of damage mechanics theory and geometrical mathematical description, respectively. It was found that both of the proposed models can be applied to predict the uniaxial compressive stress-strain relationships of PVA-SHCC and MsHySHCCs.</p> C. Zhang, Z. Yuan, Y.

Contrary to this, conventional techniques cause damage to the structure. The magnetic flux leakage (MFL) method is a non-destructive test technique commonly used to assess the physical status of construction materials. Within the framework of this study a magnetic flux leakage device was produced to detect the properties of reinforced concrete construction elements. The produced magnetic flux leakage device was used for measurements in 4 different test systems created in the laboratory environment and the results were interpreted. Thus, it was revealed that the detection of reinforcement in structures can be performed more rapidly and without damage with the MFL method.</p> Ö. Bektaş, Y.C. Kurban, B.

Several design guidelines on the confinement of FRP concrete have been developed over the past few years worldwide, each proposing a different approach, resulting in different predictions. This study aims to evaluate and compare nine international design guidelines used to predict the compressive strength of confined concrete in FRP-strengthened concrete columns and weigh them against experimental results. The results of this investigation reveal that the predictions from the guidelines on the compressive strengthening of FRP-confined concrete are generally suitable for circular columns, with the ACI-440 and CNR-DT 200 guideline predictions being two of the most accurate. Nevertheless, the guidelines generally tend to overestimate the load-carrying capacity for the compressive strength of FRP-confined concrete in non-circular columns, for which further experimental work using large-scale specimens is required.</p> A.

However, the reuse of organic wastes in coatings like plasters and renders has been poorly studied. This paper shows the effect of tire rubber wastes on the mechanical properties and fire performance of gypsum plasters. The rubber waste was added to the mixture in mass percentages of 14.50% (C1) and 46.60% (C2). Flexural and compressive strength of plasters made with rubber wastes was visibly reduced as well as their surface hardness (Shore C). In addition, fire tests produced major damages through the entire 2 cm thickness of samples containing rubber wastes, as it was corroborated by X ray diffraction (XRD) and Thermogravimetric (TG) analysis. The heat transfer due to fire exposure modified considerably the chemical composition of plasters, since, on the non-exposed face to fire, the amount of gypsum (CaSO<sub>4</sub>·2H<sub>2</sub>O) equivalent to mass loss obtained by TG due to water released by these plasters made with rubber wastes, was 5.4-7.2 lower than that of conventional plasters. The results suggest that certain wastes may reduce the efficiency of gypsum plasters in protecting underneath construction and structural elements against fire.</p> F.J. Castellón, M. Ayala, M.

The free-free resonance method is a nondestructive testing technique based on the analysis of the natural frequencies of a sample. This study presents and discusses the applicability of this technique, traditionally used on soils, for the mechanical characterization of rocks. With this aim, the free-free resonance method is used to obtain the dynamic elastic modulus and shear modulus of four carbonate rocks that have been widely used as construction materials in southern Spain. The results from the nondestructive evaluation of dry and saturated rocks, in combination with petrographic characterization and uniaxial compression tests, make it possible to assess the existing relationships between the mechanical properties of carbonate rocks and to evaluate the impact of porosity and moisture content on their mechanical behavior.</p> F.

SciMAT and VOSviewer bibliometric tools have been applied in order to analyse, quantify and visualise the conceptual and social aspects of this scientific field, as well as its evolution between 1973 and 2019. The study of 843 scientific papers in this field has shown that the most important thematic area has been&nbsp;<em>Recycling</em>. In general, the common objective of the published papers was to study the efficient use of resources contained in construction and demolition waste due to their treatment to produce recycled aggregates, particularly for use in concrete. Likewise, some lacks have been observed in other areas of the analysed field, e.g. the use recycled aggregates in applications subject to less demanding regulations (mortars, precast concrete products, or green roofs).</p> Z.
