Influence of Rice Husk Ash (RHA) on the Workability of Concrete

Abstract

Rice husk ash (RHA) is the promising pozzolanic material which can be used with Portland cement in a specific proportion to produce durable concrete and with reduced impact of cement industry on environment. Effect of RHA on the fresh properties (i.e., Workability) of concrete has been studied. Workability means the ease with which the concrete can be placed and compacted without segregation. Thus, to produce a high-quality concrete, its workability is very important factor. To measure the workability of concrete slump test is the most common test that is performed. This test gives the general idea that the mix prepared is harsh, or flowable. In this study, RHA was added to concrete in different proportion as a binder. Results reveals that RHA can be used as a binder in sustainable construction.
