Effect of aggregate type on properties of hardened self-consolidating lightweight concrete (SCLC)
چکیده انگلیسی

In this study, the effects of aggregate type on the physical and mechanical properties of hardened self-consolidating concrete produced with lightweight aggregate (SCLC) were investigated. In experiments, three coarse lightweight aggregate (LWA) types, pumice, volcanic tuff and diatomite, and normal limestone aggregate were used. Different combinations of water to binder ratio and superplasticizer dosage levels were prepared for the SCLC mixtures. The total powder content (cement and mineral additives) was constant in the experiments. Physical properties such as thermal conductivity, dry unit weight, porosity and capillarity; mechanical properties such as compressive and splitting tensile strength, modulus of elasticity and abrasion resistance were determined in hardened condition. The results, in general, showed that SCLC with LWA in lower unit weight has lower mechanical and physical properties except for thermal properties when compared to properties of SCC.
