A Study on the Investigation of Performance about Quick Measurement Technology of Unit Water Content at Mixing Factor of High Strength Concrete

고강도 콘크리트의 단위수량 신속 측정기법별 배합요인에 따른 성능 검토에 관한 연구

On investigation about quick measurement technology of unit water at range of W/B=35% in high strength, the average error of the Di-electric constant moisture tester A has measured more than $23.0kg/m^3$ unit water content of design and the average error of the method of unit volume weigh was less than $-9.6kg/m^3$. The average error with mixing factor has influenced with a kind of sand, but had not influenced with unit water content of design. Therefore, it will be for introduce business decide require more than a study about cement, sand, superplasticizer, etc.
