The study on the influence of early age damage concrete its long-term strength development is great importance. In this work, 102 cubes with and without supplementary cementitious materials (SCMs) were prepared. pre-loading loading degrees 20%, 50%, 80% corresponding compressive at 3-, 7-, 14-, 28 d was applied to samples. Then, samples further cured 270 d, tested by uniaxial compression test. ...

Replacement of cement with supplementary cementitious materials (SCMs) is a proven method to reduce clinker in and contribute decreased CO2 emissions. Natural clays are commonly occurring that do not possess pozzolanic activity their original state. Mechanochemical activation (MCA) can be an alternative sustainable enhance reactivity. In this study, the reactivity three natural clays, originati...

Concrete is frequently utilized infra-structural construction material all over the world. Cement main part of concrete, during its manufacturing emission gases such as carbon dioxide (CO2) from cement factories create greenhouse effect. In these days various natural pozzolanic materials are used partial replacement to enhance strength and durability reduction in consumption consequently emissi...

The cement industry faces an increasing demand for new supplementary cementitious materials (SCMs) as alternative to slags and ashes, the sources of which are in continuous depletion. This study reports on characteristics synthetic aluminosilicate glasses derived from basalt composition (BGs) SCMs. pozzolanic activity developed well their influence hydration kinetics, microstructure, mechanical...

Global warming is one of the main problems that facing modern civilization. As buildings consume 40% total energy, heating in cities a primary concern. Therefore, it seeks to improve sustainable construction materials with better thermal and reflective properties, reducing consumption heat islands. In this work, mineral engineered feldspars have been used as partial substitution white cement, w...

The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial pozzolan. The physicochemical properties of cem...

Abstract The mechanical properties of concrete based mainly on flexural and compressive bearing capacity. Generally, researchers have an interest in the evaluation compression property through importance performance material constructions, namely significance each upon position structural element. present experimentally work is directed toward improving strengths ordinary hardened cement paste ...

This paper aims to propose and characterize a sustainable hydraulic mortar entirely obtained by the reuse of waste materials, with marble slurry coming from quarries in north-western Sicily glass powder collection plant Marsala (Province Trapani). The first was used as raw material produce binder kilning slaking process, while second pozzolanic additive. chemical morphological characterization ...
