An Experimental Study on the Properties of Concrete by Grain Shape of Coarse Aggregate

굵은골재의 입도에 따른 콘크리트의 특성에 관한 실험적 연구

This study is to consider the influence strength of concrete according to the kinds of coarse aggregate. The experimental study conditions are varied with different maximum size of coarse aggregate(13mm, 19mm, 25mm) and the weight of water and S/a are constant. The compressive strength properties of the concrete at 7 days, 28 days are examined. According to the experimental results, the compressive strength increased and air content, slump decreased with maximum size of coarse aggregate increased.
