Abstract
Substitutes for concrete binders were introduced with the name geopolymer. Geopolymer is a concrete technology that utilizes polymerization reactions in the binding process. Rice husk ash is by-product material that has a high silica content (SiO2). The purpose of this study is to determine the effect of using rice husk ash as pozzolanic on lightweight geopolymer concrete with foam agent to the compressive strength of concrete cubes. Mix design of lightweight geopolymer concrete using ratio of Sodium Silicate:Sodium Hydroxide is 2.5:1. Curing time of the concrete by heating in an oven for 24 hours at 80oC. The study results obtained from testing the compressive strength of lightweight geopolymer concrete at 28 days, with comparison of rice husk ash and alkali activator 50%:50% resulted in the highest compressive strength of 1.87MPa. Light concrete compressive strength with ash ratio of geopolymer rice and alkali activator, 60%:40% and 70%:30%, is 1.46MPa and 1.36MPa
