Abstract

Rice husk is the remaining residue after the grain is removed. Rice milling produced 78% weight of rice rest 22% is husk, rice husk is firing using furnace with certain temperature to produce rice husk ash (RHA). The rice husk is an unnecessary waste of rice, with many opinion of research about rice hush is can enhance the strength and properties of concrete, hence this proposed research. The purpose of this paper is to investigate the properties of rice husk ash (RHA) as blended cement. The effect of grinding on the particle size and the surface area was first investigated, then, to verify the characteristic of rice husk ash on physical and chemical properties to know their density, color, fineness effective, shape and the chemical element involved. Furthermore, the effect of RHA average particle size and percentage on concrete workability, superplasticizer content and the compressive strength influence the properties of cement. Although grinding RHA would reduce its average particle size. Incorporation of RHA in concrete increased water demand and gave excellent improvement in strength. Another interesting observation from this paper is the relationship that exists among water absorption and chloride penetration. Increasing RHA fineness enhanced the strength of blended concrete compared to coarser RHA and control OPC mixtures. The rice husk ash is an agricultural waste has plenty of used. It is hope this paper statement will improve the cement industry properties and strength using rice husk ash as blended cement.
