The Development of rice husk ash and fly ash to replace portland cement in high-strength concrete work

Abstract

This research presents a study of the use of classified fly ash and ground rice husk ash as a pozzolanic material in producing high-strength concrete. Portland cement (CT) is partially replaced with classified fly ash and ground rice husk ash by weight of the cementitious materials. Compressive strength, porosity and chloride penetration were investigated. The results show that the compressive strength, resistance to chloride and low porosity of high-strength concrete improves substantially with partial replacement of Portland cement with fly ash and rice husk ash.
