A Study on Properties of High Strength and High Flowing Concrete using Blast Furnace Slag according tn the Temperature Condition

This study is to investigate properties of high strength.high flowing concrete using blast-furnace slag in temperature conditions of 5, 10, 15 and $20^{\circ}C$. The result of this study can be summarized as follows. 1) The use of blast-furnace slag leads to decrease of air content and increase of fluidity in the fresh concrete. 2) The early compressive strength of high strength.high flowing concrete containing blast-furnace slag is lower than the case with portland cement only. 3) The compressive strength development of incorporating in the concrete is poor at low temperature below about $15^{\circ}C$.
