Development of Cement Paste with Composite of Corn Husk Ash

Abstract

This paper is a study on impact test behavior of composite between cement paste and corn husk ash. In order to help the environment for future, the idea of mixing biodegradable material in original composition is something that could be an idea for designing sustainable product. Because of that, it is better to make use corn husk into something useful by mixing the corn husk ash with cement paste rather than by just using only cement with water and sand to create concrete. The objectives of this study are to identify the effect of curing days and amount of corn husk in composite mixture and examine the strength of impact force on the composite mixture. A combination of mixing cement with varied percentage of corn husk (0%, 25%, 50% and 75% by weight) and sand (1:2 ratio) and fix amount of water (0.6 ratio) will be carried out in order to determine the impact strength in this mixture. This study uses 7, 14, 28 and 56 curing days in order to determine the most optimum parameter since curing days gives effect to mechanical properties. Based on this study, result mixing corn husk ash create same impact strength or even better than the actual cement mixture with combination as in parameter.
