In this paper,through the axial compression test of lightweight aerated concrete after high temperature, the relationships between temperature and mechanical properties,such as compressive strength,elastic modulus and peak strain,are obtained. The results showthat the compressive strength of lightweight aerated concrete increases slightly at 100 ℃, and decreases gradually at 300 ℃. When the temperature exceeds 300℃,the strength change indistinctively. At 100 ℃,the elastic modulus remained basically unchange...
