A Fundamental Study on the Consistency of Base Concrete Influencing on the Worability and Engineering Properties of Folwing Concrete

유동화콘크리트의 시공성 및 공학적 특성에 미치는 베이스콘크리트의 시공연도에 관한 기초적 연구

The objective of this report is to investigate and analyze the influnce of the different base concrete in consistency for the good production of superplasticized concrete (SPC) on the basis of the experimental results. The principal conclusions are summarized as follows. 1. SPC exhibited only slight bleeding in both cases of low and medium consistency of the base concrete, compared to the conventional concrete, compared to the coventional concrete. 2. SPC lost slump and flow value at a much faster rate than the conventional concrete with an equivalent water/cement ratio and initial consistency. 3. The compressive strength of SPC was fount to be higher than that of base and conventional concrete, and the case of base concrete with medium consistency showed a little more incretment than low consistency
