Study on Mechanical Property and Strength Formation Mechanism of Red-Mud and Fly-Ash Aerated Concrete

Abstract:

Red mud is the waste which is generated in the process of extracting alumina from bauxite. In this paper, results showed that aerated concrete preparated with red mud, fly ash and other solid industrial waste, its strength can reach 2.5 ~ 5.5MPa, density of 550 ~ 800kg/m³, radioactive limit meet the requirement of material to the wall. Use of red mud to produce aerated concrete is an effective way with good environmental and economic significance.
