고강도 콘크리트의 자기수축 변형에 대한 실험적 연구

An Experimental study on Autogenous Shrinkage strain of High-Strength Concrete

The autogenous shrinkage is a important phenomenon of high performance concrete since it may decrease the concrete member's durability by induce crack at early age. So the autogenous shrinkage behavior of high strength concrete was studied according to different replacement ratio of silica fume and fly ash. A linear measurement technique which was introduced by the JCI autogenous commitee was used.
