This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine rice hush-bark ash. Portland cement (CT) is partially replaced with pozzolans 20 30 and 40% by weight of the cementitious materials. The results show that the compressive strength tensile strength flexural strength and low water absorption of Cellular Lightweight Concrete improves substantially with partial replacement of Portland cement with rice hush-bark ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials

This research presents a study of the compressive strength porosity chloride penetration resistance to carbonation and corrosion of self-compacting concrete containing fly ash ground rice husk-bark ash and ground bottom ash. Portland cement (CT) is partially replaced with pozzolans 0-40% by weight of the cementitious materials. Fly ash ground rice husk-bark ash and ground bottom ash have a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of self-compacting concrete improves substantially with partial replacement of Portland cement with fly ash. Self-compacting concrete mix cement containing 20-40% of pozzolans can be used to make cementitious materials. The use of fly ash ground rice husk-bark ash and ground bottom ash produces concrete mix with good strength and resistance to chloride and corrosion.
