In the present scenario where the constructions are increasing, the need to find a supplementary Cementing material for the improvement of strength and which has less environmental effects is of great significance.
The main objective of the research work is to investigate the possibility of utilizing cellular lightweight concrete and autoclave aerated concrete block dust as partial replacement of cement. The basic properties like consistency, specific gravity was determined and compare with ordinary Portland cement. SEM, EDX and XRD analysis is also performed for chemical composition and crystallography of utilizing cellular lightweight concrete and autoclave aerated concrete block dust. The result of the study shows that up to 20% replacement of cellular lightweight concrete block dust gives more strength that normal mortar cube. However, large levels of replacement lead to delayed hydration of the mix and porous microstructure and consequently lower compressive strength of cube. From the XRD analysis of cube sample shows that 20% replacement of cellular lightweight concrete block dust has more calcite component than 0% replacement of mortar cube.
