The innovation of rice husk-bark ash on green lightweight concrete

Abstract

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
