Abstract
Rice husk ash (RHA) is an agricultural by-product that has the potential of a pozzolanic material. It can be used as a partial replacement of Ordinary Portland Cement (OPC) in concrete. The present study investigates the performance of RHA-modified concrete with two amounts (10% and 20% by weight) of three types of RHA. Test results of RHA-modified concrete samples have been compared with those of the Control (no RHA) as well as concrete modified with a commonly used modifier called Class C fly ash (CFA) with 10% replacement. Effects of alkali-silica reaction (ASR) and deicing chemicals have also been evaluated by testing mortar bars to predict their performance under adverse weather conditions. Concrete samples with 10% Fine RHA have exhibited comparable performance of CFA-modified concrete. Finally, statistical analyses were conducted using the One-way ANOVA method to determine the significant differences of means of test data.
