Abstract
본 연구는 경량골재 대신에 일반 골재를 사용하고 기포제만 혼입을 통해 콘크리트 안에 무수히 많은 독립기포를 발생시켜 밀도가 낮은 구조용 경량콘크리트를 개발이다. 또한 개발한 구조용 경량콘크리트의 압축강도를 추정에 관한 연구도 실시하였으며 연구의 결과는 구조용 경량기포 콘크리트(밀도 1.8t/m3∼ 2.0t/m3)를 만들기 위한 기포제 첨가율은 0.3%∼0.6%에 속하며 공극률은 20∼25%범위로 나타났다. 또한 추정식에 의해 계산된 압축강도 또한 실험 압축강도와 유사한 강도를 나타내는 것을 알 수 있었다.
Instead of a lightweight aggregate, this study using the general aggregate in the concrete by mixing foaming agent raises a myriad of low density is the development of structural lightweight concrete. The compressive strength of structural lightweight concrete was developed in the study was conducted to estimate. The results of the study structural lightweight concrete foam (density 1.8t/m3∼2.0t/m3) the rate of addition of foaming agents to create a 0.3∼0.6% belongs to the porosity of the 20-25% range, respectively. In addition, the expression is calculated by estimating the compressive strength and compressive strength test is similar also to indicate the strength was unknown.
