Abstract
In order to promote the application of recycled aggregate in hydraulic concrete slope protection material,this paper studied the effects of different recycled coarse aggregate on slump,mechanical properties,drying shrinkage and chloride ion penetration resistance of con-crete by using different recycled coarse aggregate to prepare concrete and then modified it.The test results show that the use of recycled coarse aggregate will reduce the overall performance of concrete,but after modification treatment,the performance of concrete is significantly im-proved.Compared with the unmodified recycled concrete(RAC-1),the slump,compressive strength,tensile strength,drying shrinkage and electric flux of the modified RAC-4 were increased by 34.09%,12.93%,16.68%,3.25%and 43.24%,respectively.The results show that the performance of recycled aggregate can be improved significantly by modifying it to meet the needs of practical application.关键词
