摘要: Nowadays, finding appropriate solutions for reducing the environmental pollutions as a consequence of buildings is important. Using recycled concrete from demolished an aggregate in new preparation can have significant role sustainable development industry; therefore, this research work, effect employing different percentages (i.e., 20, 40, 60, 80 and 100%) aggregates impact using metakaolin pozzolan self-compacting containing SiO2 nanoparticles were investigated. Hence, some properties hardened such compressive strength, tensile modulus elasticity, water absorption, density apparent porosity samples studied. The results demonstrate that construction with complete replacement possible. Although strength concretes almost 11% less than control samples, use optimum percentage additives cement leads to improvement properties.
