摘要：

According　to　the　performance　differences　between　foam　cement　with　the　rapid　hardening　sulphoaluminate　cement　and　that　with　ordinary　portland　cement　for　cementing　material　at　different　baking　temperatures,　we　investigated　the　change　laws　of　moisture　content,　compressive　strength,　tensile　strength　and　thermal　conductivity　at　various　temperatures.　The　experimental　results　show　that　the　thermal　conductivity　is　constant　for　about　0.06　W/(m·K);　the　loss　of　lattice　H2O　leads　to　the　decrease　of　strength　in　the　drying　process;　Ca2Al3(SiO4)　(Si2O7)O(OH)　formation　leads　to　the　decrease　of　strength　at　drying　temperature　of　105°C.
