对高强混凝土的自收缩应变及由自收缩和水化热效应引起的约束应力进行了试验研究。很明显，在早期，不含外加剂的混凝土和含硅灰的混凝土的自收缩应变比含高炉矿渣的混凝土发展得更快。掺矿渣混凝土的自收缩终应变最大，不掺矿渣混凝土的自收缩终应变最小。
The autogenous shrinkage strain and restrained stress due to autogenous shrinkage and heat of hydration effects in high strength concrete were investigated experimentally. It was clear that at early age the autogenous shrinkage strains develop more rapidly in concrete without admixture, and in concrete containing silica fume, than in concrete containing blast furnace slag. The final autogenous shrinkage strains in concrete containing blast furnace slag are largest, and are smallest in concrete without admixtures.
