Effect of temperature on the rate of gain of strength of concrete

Abstract

This paper presents the effect of temperature on the rate of gain of strength of concrete. Different samples of concrete were cast at different temperatures and various properties of concrete in fresh and hardened state were determined. It was observed that the three strength parameters viz. the compressive strength, the split tensile strength and the flexural strength of concrete are adversely affected when the temperature during first 24 hours is less than or equal to zero degree Celsius. The compressive strength of concrete was determined using 100mm and 150 mm cubes and a comparison was made between the two. It was observed that the strength of 100 mm cubes was greater than that of 150 mm cubes. Later a relationship was developed between 7 days,14 days and 28 days strength.
