A Fundamental Study on Effecting of Admixture on Physical Properties of Antiwashout Concrete

An experimental study was carried out for the estimate of the properties of concrete contained an antiwashout admixtures. Properties of antiwashout under water concrete clearly differed from other types of concrete. This paper reports the effects of specific types, dosage of antiwashout admixtures and superplasticizer. The test results have indicated that dosage of antiwashout admixture and superplsticizer to improve the antiwashing property, fluidity and compressive strength will be approximately 2.5kg/$\textrm{m}^3$, 8~10kg/$\textrm{m}^3$ of the weight of concrete each. When cellulous ether type antiwashout admixture is added with a napthalen sulphonate superplasticizer, resulting in reduced whole properties of antiwasout under water concrete.
