Different mix proportions of shale ceramsite concrete were designed. The spalling of shale ceramsite concretes with different moisture contents(by mass) after exposure to 600℃ was observed. And mass loss and relative residual compressive strength of shale ceramsite concrete after exposure to 200, 400, 600, 800, 1000℃ were tested. The results indicate that the spalling rate of shale ceramsite concrete increases with increasing use level of shale ceramsite in concrete, and the higher the moisture content in shale ceramsite concrete, the higher the spalling rate. The spalling of full lightweight aggregate concrete with 580kg/m3 shale cermasite added is prevented by incorporating 0.91kg/m3 reticular polypropylene fiber of 20mm length. The mass loss of full lightweight aggregate concrete is less than that of ordinary concrete after exposure to 800℃ and 1000℃. As the temperature rises, the relative residual compressive strength of shale ceramsite concrete declines. And the higher the use level of shale ceramsite, the higher the relative residual compressive strength of concrete.
