摘要
研究了不同胶集比、不同养护条件对超高强高性能混凝土体积变形的影响;探讨了石灰石粉对超高强高性能混凝土体积变形的影响。试验结果表明,水泥净浆的收缩显著地高于砂浆和混凝土;不同养护条件下的混凝土的体积变形差别较大,且水养护会产生湿胀变形的现象;石灰石粉对超高强高性能混凝土的体积变形有抑制作用。
This experimental studies the volume deformation of the super high strength and high performance concrete for different binder-aggregate ratio and different curing condition; then discusses the influence of limestone powder on the vohune deformation.The results indicates that the deformation of cement slurry is much higher than mortar and concrete;for the different curing condition,the difference is notable, and there is a moisture swell deformation for the water cured concrete; the limestone powder can reduce the volume deformation of the concrete.
