摘　　要：通过对聚合物砂浆、M10水泥砂浆以及C30混凝土试块高温后力学性能试验研究,发现试块强度并不是随温度的升高单调下降,在低温时强度有所恢复,但最终都是随温度升高而衰减.相对于水泥砂浆,同样高温后聚合物砂浆的实际强度更高,且具有较好的抵抗温度应力和阻裂的性能.Experimental studies on the mechanical properties of polymer mortar,M10 cement mortar and C30 concrete after high temperature were carried out.It was found that the strength of the specimens did not decrease monotonously with increasing temperature.The fire-exposed polymer mortar specimens have a higher strength and a better performance of resistance of temperature stress and crack than the cement mortar ones.
