Abstract

The research was carried out about the effect of adding rice husk ash to physical and mechanical properties of mortar. Mortar was moulded with three composition comparisons between ordinary portland cement, rice husk ash, and rice stalk fiber. Rice husk ash was burned at temperature of 700 OC for 2 hours, rice stalk fiber was mechanically sliced up to 0.8 mm in size, then mortar molding and maintenance was processed for 28 days. The mortars that had reached the age of 28 days were tested according to the  Indonesia National Standard (SNI) including physical properties (water absorption, density), and mechanical properties (compressive strength, modulus of elasticity, modulus of rupture). Characterization of microstructure, morphology and counting all elements on the surface of  mortar were processed by using Scanning Electron Microscopy - Energy Dispersive X-ray Spectroscopy (SEM-EDS). The results of research that had been carried out, mortar with the most optimum physical and mechanical properties was mortar B with a composition of 65%: 10%: 25%. The results of the characterization using SEM-EDS showed that the surface of mortar B was better with grain diameter (1.4 ± 0.9) µm and the most dominant element in the mortar was element of Ca and Si which functioned as mortar binder and hardener.
