TIME AND TEMPERATURE EFFECTS ON TENSILE, BOND, AND COMPRESSIVE STRENGTHS.

The article describes an experimental investigation into the relationship between bond strength, tensile strength, and cylinder strength of concretes made of Type I cement and Type III cement moist cured at 22 C for 1, 3, or 7 days and then cured under extended low temperatures of 13 C and 2 C. Compression strength, tensile strength, and bond strength are all related, and an increase in one is reflected similarly in the others. The tensile strength and bond strength were found to be proportional to the 0. 8 power of the cylinder strength with respect to age.
