Abstract:
The strength of concrete is determined by the degree of hydration of cement in the concrete. Using this assumption, the authors experimentally obtained the rate of hydration of cement and showed that regardless of the age of concrete, there is a linear relation between the effective cement-water ratio and the strength of concrete. A formula for expressing this relation is presented. Thus, if the cement-water ratio is given, the compressive strength of concrete at an arbitrary age can be estimated.
