Abstract

In this studies, methly celluloes was used as antiwashout admixture and when considering the physical properties and economical efficiencies of Underwater Concrete as the results of making an experiencing slump flow, flow loss, setting time, suspension and pH also compressive strength and underwater/an air compressive strength ratio according to the adding amount changes 5, 7, 9, 11 kg/$m^3$ to Underwater Concrete of melamine superplasticizer, the using amount of melamine superplasticizer in Underwater Concrete approximately represents 9 kg/$m^3$.

본 연구에서는 수중불분리혼화제로서 메칠셀룰로스계를 사용하였고 자체 개발한 멜라민유동화제의 수중불분리콘크리트에 대한 사용량을 5, 7, 9, 11 kg/$m^3$으로 첨가량을 달리하여 slump folw, flow loss, 응결사간, 탁도 및 pH, 압축강도, 수중/기중 압축강도비를 실험한 결과 수중불분리콘크리트의 물성이나 경제성등을 고려할 때 수중불분리콘크리트에서의 멜라민유동화제의 사용량은 약 9 kg/$m^3$인 것으로 나타났다.
