Study on Light Porous Unsintered Building Material
A light porous unsintered building material was prepared with red mud, fly ash, silica fume as the main raw materials, mixed with a certain amount of foam and curing agent, by the technology of casting and curing at ambient conditions. The influence of different ratio of red mud to fly ash on compressive strength was studied. The microstructure properties of light porous unsintered building material were characterized by scanning electron microscopy (SEM) and then the strength mechanism was studied. The results showed that the optimum ratio of red mud to fly ash was 2:1, and for the best sample, its bulk density was 891 kg·m-3, 7d and 28d compressive strength were 8.4 MPa and 14.7 MPa, thermal conductivity coefficient was 0.235 W·(m·K)-1, which may have a broad application prospect in the building materials field.
