Effect of Rice Husk and Rice Husk Ash to Properties of Bricks

Abstract

This research has aims to study effect between rice husk and rice husk ash to properties of bricks. Comparative adding between rice husk and rice husk ash were varied by 0 -10% by weight. The results showed that more adding rice husk less compressive strength and density of specimens. Otherwise the porosity increases when adding rice husk. By adding 2% of rice husk ash by weight is the best of bricks properties which 6.20MPa of compressive strength, 1.68g/cm3 of density, and 15.20% of water absorption.
