영문초록
This study is an experiment about what affects the compressive strength by using a reducing agent (PNS based admixtures) to play cement using the cement paste based Waste Concrete Powder of waste concrete , which accounts for more than 60% of construction waste around the latest domestic and international It was . Securing the replacement of cement with Waste Concrete Powder and , by varying the admixture was to compensate for the low absorption of liquidity and obtain a fine powder . And the experiment was conducted with a constant water cement ratio and aggregate usage for the purpose of lowering the water cement ratio promoting strength development . When substituted with the experimental results of 0.3% based on 3 ~ 28 days as strength 36Mpa exhibited the highest strength .
