A REVIEW ON UTILIZATION OF RICE HUSK ASH IN CONCRETE

ice husk ash (RHA),a by - product of rice processing,is produced in large quantities globally every year and due to the difficulty involved in its disposal,can lead to RHA becoming an environmental hazard in rice producing countries,potentially adding to air and water pollution . Therefore it is necessary to find out the alternative for consumption or disposal of the RHA. Utilization RHA in concrete is an effective way to solve the environmental and disposal problem of the ash. Due to its pozzolanic properties it can be use as supplementary cementitious material in concrete. This ability to use RHA to substitute a percentage of Portland c ement would not only reduce the cost of concrete construction,but would also provide a means of disposing of this ash,which has little alternative uses. RHA in concrete as a partial replacement for the energy intensive Portland cement would also stand to reduce the amount of energy associated with concrete construction. Therefore,RHA has great a potential in concrete for its sustainable use. https://www.ijiert.org/paper-details?paper_id=14033
