IMPORTANCE OF AGRICULTURAL RESIDUES (CORN COB AND RICE HUSK ASH) TO CONSTRUCTION INDUSTRY IN NIGERIA: A REVIEW

Abstract

Agricultural residues are residues generated from agricultural processes. It has been discovered that the combustion of agricultural residues like corn cob and rice husk to ashes have pozzolanic properties, which means the sum of SiO₂, Al₂O₃, and Fe₂O₃ composition that meet the 70% minimum requirement according to ASTM C618-12 for a material that can partially replace cement as binding agent in construction works. The discussion of the review is on the method of chemical analysis, effectiveness, benefits, and recommended solutions on the use of corn cob and rice husk ash as alternatives to cement.
