Pemanfaatan Abu Sekam Padi sebagai Sebagian Semen dalam Pembuatan Beton

Abstract

Dusty luced up paddy directed by incediarism luced up paddy, This time, many scientist used dusty up paddy to make a material, like ceramik, etc in this research, dusty luced up paddy used as subsitute a part of cement in making concrete. The proportion of dusty luced up paddy which used is 5%, 10%, 15%, 20%, and 25% from the mount of cement. The test material are made with composition: 1 cement, 2 sand and 3 gravel to make a normal concrete, and by adding dusty luced up paddy to make concrete with mixing dusty luced paddy. The test are doing to concrete over load the test of compressive strength, porosity, and water absorbtion and from the result of the researching to indicate the used of dusty luced up paddywith proportion 5% and 10%. from the mount cement will increase compressive strength concrete up to 28,48% and 47,25%. From compressive strength normal concrete, except that, using of dusty luced up paddy which proportion 5% and 10%, the making of concrete will also smalles porosity and water absorbtion by concrete. From the result of research, water absorbtioan decrease 1,6% and 2,42% from normal concrete. And porosity of concrete decrease 2,65% and 6,22% from normal concrete.
