Thermal Strain Properties of Ultra High Strength Concrete according to the Compressive Strength

압축강도에 따른 초고강도 콘크리트의 열변형 특성

In this study, the thermal strain of high strength concrete with the compressive strength of 80, 130, 180MPa were measured under 25% of compressive strength loading condition. As results, it is considered that decline of the elastic modulus and shrinkage strain of high strength concrete become grater at the elevated temperatures.
