Flowing and Setting Properties of High Flowing$\cdot$High Strength Concrete using Blast-Furnace Slag according to the Chemical Agent

고로슬래그 미분말을 사용한 고유동고$\cdot$강도 콘크리트의 혼화제에 따른 유동 및 응결 특성

Results from a study on the effect of the chemical agent on the flowing and setting properties of high flowing.high strength concrete using blast-furnace slag are presented in this paper. The flowing and setting properties of concrete are investigated by slump, slump-flow, flowing velocity, L-flow, velocity of V-funnel, L-spatial passability and setting time. In addition, kinds of chemical agent were composed of naphthalene type, of naphthalene and melamine and melamine type. The results indicate that dispersive capacity can be increased by naphthalene composition. Also, it shows that viscosity and early strength can be increased by melamine composition.
