摘要
着眼于再生混凝土的应用,为了解再生混凝土与普通混凝土在循环荷载下损伤性能的差别,进行了本次试验研究。采用0%,50%和100%3种取代率,70mm×70mm×148mm棱柱体试件,电-液伺服试验机,等位移速率加载。试验结果表明,相同残余应变时再生混凝土的损伤系数随再生骨料取代率的增加而增加。
Focus on application of recycled concrete,and in order to finding out the difference of damage factors between the recycled concrete and the natural aggregate concrete under compression cyclic loading,this test was designed.The recycled aggregate replacement ratios of samples are 0%,50% and 100%.The size of prism samples are 70mm×70mm×148mm.By using the hydraulic servo test machine,the uniaxial compression loading tests of the samples were implemented controlled by displacements.The test results predict that the damage coefficient of recycled concrete would increase with the substitution ratio of recycled coarse aggregate.
