The Preparation and Performance Study of Thermal Insulating Materials with Diatomite

Abstract:

Diatomite was used as the main material and sodium silicate as the alkali activating solution in this paper. Diatomite light-weigh material was made by chemical foaming method. Compressive strength, density and heat conductivity were used to measure its performances. Results showed that density, compressive strength showed a growth trend while coefficient of thermal conductivity showed the opposite trend with increasing rapid hardening cement and senior gypsum.
