고강도콘크리트의 유동성 손실에 영향을 미치는 요인에 대한 실험적 연구

An Experimental Study on the Factors Influencing on the Slump Loss of High Strength Concrete

In this study , some factors such as mix proportion, type and dosage of high range water reducing admixture(HRWR) and natural pozzolanas influencing on the slump loss of high strength concrete(H.S.C) using HRWR were investigated for reducing the slump loss. The acquired results indicated that the slump loss of H.S.C was affected according to cement content, sand percentage and type and dosage of HRWR and fly ash was superior to ground granulated blast furance slag in reducing the slump loss of H.S.C.
