Abstract

In this research wood sawdust used as substitution some of cement in concrete making. rate of wood Sawdust used is 5%, 10%, 15% and 20% from amount the cement. Object test made with the mixture composition 1 cement : 2 sand : 3 gravel for the making of normal concrete. While for the addition of wood sawdust for the making of concrete with the mixture of wood sawdust. Examination conducted to concrete cover the; strong examination depress the concrete, absorbtion irrigate and porosity. From research result indicate that the use of wood sawdust with the rate 5% will improve the strength depress the concrete. Others exploiting of wood sawdust with the rate 5% and 10% to concrete making also will minimize the porosity and absorbtion irrigate. Universitas
