ABSTRACT

The applied research to known about influence of added rice husk ash as substitute for several cement in mixing the concrete and the local aggregate in Jember towards compression strength of the concrete.
Characteristic compression strength of the concrete design is 225 kg/cm2. Mix design of the concrete with done several variation percentage of the rice husk ash, Variation was 0%, 7,5% , 10% and 15%. The set up compression strength at 7 and 28 days old and done until failure reached.
The result of the laboratory testing indicated not problem for all concrete to reached characteristic compression strength. The problem used the local aggregate was absorption water and humidity water too high until influence development hardening of the concrete.

Keys words : rice husk ash, local aggregate, compression strength
