Pemanfaatan Abu Sampah Organik sebagai Pencampur Semen pada Pembuatan Mortar

Abstract

In this research, the researcher utilited organic waste ash as additive material in mortar mixture. The testing was made for physical and mechanical properties of the mortar. The testing object was made by composition of mixture 1 cement : 2,75 sand, by variation of organic waste ash addition on cement: 0%, 5%, 10%, 15%, and 20%. The result of research indicated that there was increase in pressure strength and density with increasing variation of organic waste ash mixture.The porosity of mortar indicated a decrease with increasing variation of organic waste ash mixture.
