Study on Waste Concrete as Reclaimed Fine Aggregate

This paper compares the properties of concrete made by reclaimed fine aggregate with those made by other fine aggregate. Although the properties of reclaimed fine aggregate and other kinds of fine aggregate are different, especially the strength of reclaimed fine aggregate is lower than that of manufactured sand. It is concluded that the fluidity, the strength and the elastic modulus of concrete made by reclaimed fine aggregate are almost similar to those made by other fine aggregate. When it comes to the making of concrete, reclaimed fine aggregate can serve as a substitute for other aggregate. Moreover, it can enhance resources utilization and reduce environmental pollution.
