摘要
对现有孔隙水对混凝土静力特性影响的试验和理论研究成果进行综述。总结目前的试验研究方法和结论,分析湿度梯度、孔隙水压力以及液体表面张力等因素对混凝土弹性模量和强度的影响机理,指出孔隙水对混凝土特性的影响应是多种因素共同作用的结果。
The current experimental and theoretical researches on influences of pore water on static properties of concrete were reviewed.The existing experimental methods and conclusions were summarized.The mechanism of influences of moisture gradient,pore water pressure and water surface tension on elastic modulus and strength of concrete was analyzed.A conclusion is drawn that the influences of pore water on the properties of concrete are made by various factors.
