Rice Husk Ash (RHA) is a highly reactive Pozzolanic material that can be used for replacement of cement at various percentages. The Rice milling industry generates a huge amount of rice husk during milling of paddy which comes from the agricultural field. This rice husk can be used as supplementary cementing material with Ordinary Portland cement. The main aim of this review paper is to show the modified properties of concrete made from the addition of RHA in different percentages. The effects of RHA on concrete properties such that compressive strength, workability, tensile strength shall be investigated.
