Abstract

Recycled coarse aggregate (RCA) was obtained from waste samples of C30 in the laboratory through crushing, washing and screening and cube compressive strength test was conducted on RCA concrete under different conditions. The results show that the compressive strength of recycled aggregate concrete (RAC) decreases with the amounts of RCA generally increase of the replacement ratio on recycled aggregate in the same water-cement ratio. However, when the replacing 50% the natural coarse aggregate (NCA), the compressive strength of RAC appears to jump. Two-factor analysis is used to arrange the experiment by taking a full consideration of the factors which have effect on the compressive strength, such as water-cement ratio, coarse aggregate replacement ratio, and the interaction between water-cement ratio and replacement ratio. The analysis of variance is established and is used to analyze the influence rate of the compressive strength. It also shows that main factor which affects the compressive strength is coarse aggregate replacement ratio and the interaction function on the water-cement and replacement ratio cannot be ignored. The study offers a valuable reference to the design of recycled concrete. This electronic document is a "live" template.
