通过相关试验研究在同一强度等级下,不同水灰比、单掺硅灰不同掺量对混凝土强度和早期收缩开裂的影响,对不同配合比设计的混凝土进行强度和早期收缩开裂试验,并对所得到的全部实验数据进行分析,从而得出硅灰掺量、水灰比对混凝土强度及早期收缩开裂的影响,寻求硅灰的最佳掺量范围。
The influence of different water-cement ratio and single-doped silica fume on the strength and early shrinkage cracking of concrete under the same strength grade was studied by relevant tests. The strength and early shrinkage cracking tests of concrete with different mix ratios were carried out, All the experimental data obtained were analyzed to get the effect of the content of silica fume and the ratio of water to cement on the concrete strength and early shrinkage cracking, and the optimum dosage range of silica fume was obtained.
