Abstract

For evaluating basic structural behavior of HVFA (High Volume Fly Ash) concrete, several tests are performed considering different ratios of fly ash replacement and structural evaluation regarding compressive strength, elasticity modulus, stress-strain relationship, and bond strength is also performed. Test results show that elasticity modulus of HVFA concrete has close relationships with compressive strength and fly ash replacement ratio. The ultimate strain shows slight difference from domestic design code. On the other hand, there are no differences between general concrete and HVFA concrete for elasticity modulus and bond strength.

플라이애시가 다량 첨가된 콘크리트, HVFA의 구조 기초 거동을 평가하기 위하여 플라이애시 혼입률과 압축강도를 변수로 하여 탄성계수, 응력-변형률 관계 및 부착강도 실험을 수행하였다. 실험결과에 의하면, 탄성계수는 콘크리트의 압축강도와 플라이애시 혼입률에 어느 정도 영향을 받는 것으로 나타났으며, 극한변형률 역시 기존의 설계식과 다소 차이가 있는 것으로 나타났다. 반면에 HVFAC의 탄성계수 및 부착강도는 일반 콘크리트와의 차이가 크지 않은 것으로 나타났다.
