A Fundamental Study on the Improvement of Superplasticizer for Manufacturing the High Quality Flowing Concrete in the Field

고품질 현장 유동화 콘크리트 제조를 위한 유동화제 성능 개선에 관한 기초적 연구

Generally, the base concrete for manufacturing the flowing concrete has to increase the fine aggregate content or adjust the fines content prevent the concrete from segeration, However, it may not only increase the cost, but cause the inconvenience in production of base concrete. In this paper, the experiments is performed on the superplasticizer which is used for base concrete by mixing viscosity agents and AE admixtures. According to the results, it shows that it is possible to manufacture a flowing, non segregation, high durability and economical concrete in the field without increasing the fine aggregate content of base concrete, when the superplasticizer are mixed with viscosity agents and AE admixtures in an appropriate proportion.
