Abstract:
Reports on an investigation of the relationship between concrete compressive strength and its splitting tensile strength, especially at early ages, as well as on an examination of the applicability of some of the existing relation between these properties to concrete at early ages. Analyses of test results show that the compressive strength and splitting tensile strength are related, and an increase in one generally is similarly reflected in an increase in the other. The commonly accepted 0.5-power relationship between the compressive strength and the splitting tensile strength was found to be inaccurate at all ages. In fact, the tensile strength was found to be proportional to the 0.79 power of the cylinder compressive strength. An alternate relationship between the tensile stress and compressive strength is proposed.
