Properties of Thermal Expansion Strain of Light Weight Aggregate Concrete with Loading Conditions

하중조건에 따른 경량골재 콘크리트의 열팽창변형 특성

In this study, strain properties of high strength concrete using light weight aggregate which is widely used in recent years are evaluated. For these purpose, thermal strain, transient creep were measured in prestressed condition as 0, 20, 40% of specimen strength at target temperature with 60MPa specimens which was using normal and light weight aggregate. As a result, light weight aggregate is more advantageous for the control of strain than normal aggregate because of its low thermal expansion.
