Study on Light Porous Sintered Material

Abstract:

A light porous sintered material was prepared with red mud, fly ash, silica fume as the main raw materials, mixed with a certain amount of foam, by the technology of casting, calcination and etc. The influence of calcined temperature on the flexural strength, compressive strength, shrinkage and other properties of sample was studied. The microstructure of sample was characterized by scanning electron microscopy (SEM) and then the sintering mechanism was studied. The results showed that the optimum calcined temperature was 1150°C, and for the best sample, its bulk density was 691kg•m^-3, compressive and flexural strength were 4.2MPa and 3.2MPa, thermal conductivity coefficient was 0.110W• (m•K)^-1, firing shrinkage was 3.9%.
