多孔改性水泥混凝土干温缩性能研究

多孔改性水泥混凝土是多孔、不均质材料.通过对混凝土的干缩性能、温缩性能进行研究,发现多孔改性水泥混凝土较普通混凝土和基层材料具有更好的抗干缩性能,产生干缩裂缝的可能性较小,且温缩系数小,具有比较优良的温度稳定性.

Drying and Temperature Shrinkage Performance of Porous Modified Cement Concrete

Porous modified cement concrete is a kind of porous and heterogeneous material. Through the study of drying shrinkage performance and temperature shrinkage performance of concrete, the results in- dicate that the porous modified cement concrete has excellent drying shrinkage performance and temperature shrinkage performance in contrast to ordinary cement concrete and base material. It has little dry shrinkage crack and low value of temperature shrinkage coefficient. Therefore, it has good performance of temperature stability.
