Abstract
To enhance the performance of recycled aggregate concrete,by preparing recycled aggregate concrete with different particle sizes,the influence of various factors on the working performance and mechanical properties of recycled aggregate concrete was systematically analyzed.The optimal dosage of recycled aggregate and aggregate particle size were determined,the mechanism of performance change of recycled aggregate concrete was revealed,and its environmental benefits were evaluated.The results show that with the increase of the dosage of recycled aggregates,the compressive strength and flexural strength first increase and then decrease.The active range of spectral fluctuations in the ZS-40-16 range is smaller than that of PT,and the density and stability of the internal microstructure are higher.Compared with ordinary concrete,recycled aggregate concrete has more significant environmental benefits.In conclusion,when the particle size of recycled aggregates is 16 to 21.5 mm and the dosage is 40%,recycled aggregate concrete has the best performance and environmental benefits.关键词
