摘要：

Conservation of natural resources and preservation of environment are the essence of any development. The use of recycled aggregate concrete(RAC) is an attempt and an answer to some of the problems in constructional engineering. So recycling the decasting concrete catches more attention in the world. It depends on the strength for construction bearing to utilize recycled concrete(RC), but the strength calculation formula of RC has not been put forward yet. There is a linear relation between the common concrete compression strength and cement strength with cement-water mass ratio, whether this relationship also exists in recycled concrete or not it should be verified by experiment. Based on some experiments, the relationship between recycled concrete compression strength and its cement-water mass ratio was established, and the method to determine A' and B' values in Bolomey Formula was discussed.
