摘要
为研究内埋聚氨脂胶管混凝土的自修复效果,设计了10组混凝土试件,通过控制试件的裂缝宽度,进行不同加载形式(弯和剪)的混凝土自修复试验,提出了自修复效果计算式,并验证了其合理可靠性.结果表明:由混凝土自修复效果表达式得到的计算值与试验值基本相符,试验值未超过计算值的3.97%,两者之间存在的差值可作为安全储备.
For calculation of repair effect of the self-repairing concrete,10groups of concrete specimens were designed.Through controlling the crack width of the specimens,concrete repair tests of different loading forms(bending and shearing)were carried out,and the calculation formula of repair effect was put forward.The calculated value obtained from the concrete repair effect expression is basically in agreement with the test value.The actual test value does not exceed 3.97%of the calculated value.The difference between them can be used as a safety reserve.
