摘要
通过对大孔隙无砂混凝土与普通混凝土的干缩及温缩性能进行对比试验,表明该种材料较普通混凝土有更好的抗裂性能,对于温度的变化表现出更强的体积稳定性,其抗收缩性能要优于普通混凝土。在此基础上,对其机理也进行了分析。
The contrast tests between the porous concrete and normal concrete were carried out in dry shrinkage and temperature shrinkage. The results have shown that the porous concrete has a better crack resistance than normal concrete, with showing volumetric stability to change of temperature This article describes the mechanism of shrinkage and shrinkage performance.
