Abstract
In the investigation of the existing Prestressed Concrete structures on the deterioration, the several examples of the defects of PC grout have been reported.The quality improvement of PC grout has been requested. In this study, the formulations that predict the bleeding and the efflux time for flow from J14 funnel have been done for PC grout made by adding the quenched blast furnace fine slag and the superplasticizer. Through the formulated equations, the parametric study has been carried out for the effect on the bleeding and the the efflux time of PC grout. Moreover, the mix proprtion design to improve the quality of PC grout has been investigated.
