A Study on the Investigation of Performance for Evaluation Method of Unit Water Content of Fresh Concrete

굳지 않은 콘크리트 단위수량 추정기법의 성능 검토에 관한 연구

In this study, air meter method and capacitance measurement method to apply economically at quality control of ready-mixed concrete among various unit water content measurement technique was selected. Then, it was evaluated estimating performance of unit water content according to the change of water-binder ratio and unit water content. Also, it was examined influence about error occurrence of unit water content by change of properties of used materials. Finally, based on this study, it was proposed fundamental data to utilize measurement technique of unit water content to quality control. of ready-mixed concrete in construction field.
