Tests and Models of Hydraulic Concrete Material with High Strength

Abstract

The paper describes an investigation into the comprehensive sensitivities of Sino high strength hydraulic concrete to the addition levels of fly-ash powder and silica fume. Four fly-ash powder addition schemes (100, 120, 140, and 160 kg/m3) and four silica fume addition schemes (12.5, 17.5, 22.5, and 27.5 kg/m3) were considered, respectively. The curing ages’ effects were incorporated in this study. The sensitive feedbacks, including creep development, temperature rise procedure, and strain-stress constitution, have been analyzed. The simulation and test results indicate that the Sino high strength hydraulic concrete, prepared by 140 kg/m3fly-ash powder and 22.5 kg/m3silica fume, gives the superb strength, durability, and creep stability.
