주물공장에서 배출되는 플라이애시를 이용한 콘크리트의 특성에 관한 실험적 연구 (I)

An Experimental Study on the Characteristics of Concrete using Casting Foundry Fly Ash (I)

The purpose of this study is to examine the raising of strength of concrete and workability using casting foundry fly ash. First, we conducted analysis of chemical components of fly ash. Then, we tested uniaxial strength of concrete at ages of 3, 7, and 28 days. As a result, we found that the strength of concrete using casting foundry fly ash is raisen up 16% than plain concrete when the fly ash is added 0.6% of weight of cement.
