TL;DR: In this paper, the results of laboratory research that examines the incorporation of tire rubber granules as a partial replacement for the sand in cement mortars have been presented, showing a decrease in mechanical properties, whereas an increase in chloride ion penetration resistance has been observed.
Abstract: Disposal of worn tires poses a major problem worldwide. In Greece more than 50,000 tons of worn automobile tires are stockpiled annually. This paper presents the results of laboratory research that examines the incorporation of tire rubber granules as a partial replacement for the sand in cement mortars. Physical and mechanical properties of these rubber mixtures are studied while, for the first time, resistance to chloride ion penetration is measured. Results showed a decrease in mechanical properties, whereas an increase in chloride ion penetration resistance has been observed. This implies that cement-based mortar and concrete products, modified with tire rubber granules as a partial replacement for the sand, can be used in applications where mechanical properties are not of prime importance but where high resistance to chloride ion penetration is demanded.

TL;DR: In this paper, the differences of effect of silica fume in paste, mortar and concrete were studied by determining the non-evaporable water content of pastes, measuring the compressive strengths of pasted, mortars and concretes containing 5% and 10% raw silica Fume, respectively, with water-to-binder ratios (W/B) of 0.29 and 0.24 and investigating the properties of interfacial transition zone between hardened paste and aggregate.

TL;DR: In this paper, an experimental study on the tensile behaviour of reinforced concrete and masonry structures was presented, where various clamping methods and testing setups have been experimented and their effect on the results is discussed.
Abstract: Textile reinforcements applied with inorganic matrices are currently receiving great attention for strengthening reinforced concrete and masonry structures, especially when preservation criteria need to be fulfilled for safeguarding cultural heritage. As the development of mortar-based reinforcements is still at an early stage, their mechanical properties need to be investigated and standardized testing methodologies have to be defined. The paper presents an experimental study on the tensile behaviour of strengthening systems comprising two different textiles and five mortar matrices. Various clamping methods and testing setups have been experimented and their effect on the results is discussed. Monotonic and cyclic tests have been carried out to derive strength and stiffness, crack pattern, failure mode, and response stages under tension, which have been related to the mechanical properties and the layout of the matrix and the textile.

TL;DR: In this paper, the intrinsic properties of recycled coarse aggregates (RC) associated with bonded mortar were modified with two different pretreatment techniques viz-a-viz HCl pretreatment and Na2SO4 pretreatment, while maintaining a fixed aggregate-to-solution ratio of 1:4.5.

TL;DR: In this paper, the authors used ground clay bricks (GCB) as a pozzolanic material to minimize the alkali-silica reaction expansion and found that the GCBs were effective in suppressing the reaction expansion.
