Approaching Regression Coefficients in Recycled Concrete Bolomey Formula

摘要

There is a linear relation between the common concrete compression strength and cement strength with cement-water ratio, whether this relationship also exists in recycled concrete or not should be verified by experiment. Based on some experiments, the relationship between recycled concrete compression strength and its cement-water ratio is established, and the method to determine A' and B' values in Bolomey Formula is discussed.
