伊利石粘土对再生混凝土抗压强度的影响研究

Experimental study on the influence of illite clay on compressive strength of recycled concrete

制备了6组不同伊利石粘土掺量的再生混凝土试块,对3 d,7 d,28 d,60 d不同龄期不同掺量的再生试块进行了对比,分析了伊利石粘土的掺量与再生混凝土抗压强度的关系,结果表明,龄期3 d时,伊利石粘土的添加减缓了再生混凝土抗压强度的增长,7 d,28 d,60 d时伊利石粘土的添加加快了再生混凝土抗压强度的增长。

Six groups of recycled concrete blocks with different Illite clay contents were prepared,3 days,7 days,28 days and 60 days of different ages were tested with different amount of recycled samples,in order to study the relationship between the content of Illite clay and the compressive strength of recycled concrete. Research shows that： on the 3 day,the addition of Illite clay slowed the growth of compressive strength,and the addition of Illite clay accelerated the growth of compressive strength on the 7 day,the 28 day and the 60 day.
