Performance Study Of Fibre Reinfoced New Lightweight Insulation Materials

Cement-based lightweight insulation materials were made. Cement and fly ash are main raw materials. The self-developed composite excitation agent and foaming agent are used. The method of foaming is the physical foaming. The inflection of fiber dosage on the performance of lightweight insulation materials was researched. Its influencing mechanism was discussed. Experiments show that foaming lightweight insulation materials were made with 1.22MPa bending strength, 2.95MPa compressive strength and the 0.072W/mk coefficient of thermal conductivity when the fiber mixing content is 1.2%.
