Experiments on Mechanical Characteristics of Anti-Washout Concrete with Mixing and Placing Condition

배합 및 타설조건에 따른 수중불분리성 콘크리트의 역학적특성 변화에 관한 실험

An experimental study is carried out to estimate the effects of mixing and placing condition on the mechanical properties of anti-washout concrete. According to the test results, mixing method and placing temperature do affect the characteristics of rrsh concrete, while they do not affect the strength development of anti-washout concrete. But, concrete strength was greatly affected by the placing condition and placing height. Concrete strength decreases linearly as the placing height increased. Compared to the normal concrete, the increase in strength is not associated much with an increase in the elastic modulus of anti-washout concrete.
