Evaluation on Mechanical Properties of High Strength Concrete according to the Aggregate Type and after Heating Cooling Conditions

가열 후 냉각조건에 따른 골재 종류별 고강도 콘크리트의 역학적 특성 평가

Aggregate thermal properties and cooling methods are most important to evaluate the residual mechanical properties of concrete. In this study, we evaluate the residual mechanical properties of concrete according to the aggregate type and cooling method. We use the normal weight aggregate and light weight aggregate which have different thermal properties. After heating to the target temperature, we evaluate the mechanical properties according to the slow and fast cooling condition. As a result, normal weight aggregate concrete has higher effectiveness of cooling conditions than light weight aggregate concrete.
