Abstrakt: The hard silicon calcium stone slurry were synthesized by dynamic hydrothermal synthesis in this article, the influence of water solid ratio and carbon fiber on the performance of the calcium silicate thermal insulation material was studied. The results showed that when the water-solid ratio of 40, sodium dodecyl benzene sulfonate cited as a foaming agent, the sphericity of spherical particles was well, and xonotlite fiber developed well. The added carbon fiber could significantly increase the flexural and compressive strength and coefficient of thermal conductivity of the material. The microstructure of calcium silicate insulation material was observed and analyzed by scanning electron microscope.
