摘要
针对混凝土高脆性的不足,重点研究了不同配合比、掺合料和外加剂对凝石混凝土脆性的影响。通过改进掺合料、优化配合比和添加外加剂,在抗压强度不降低的情况下,改善了凝石混凝土的内部微观结构,降低混凝土的弹性模量,在一定程度上改善了材料的脆性。
The influence of the different matched ratio, concrete additive and additional dos on the high brittleness of concrete was studied By means of improving the additive, optimizing the matched ratio and increasing the additional dose, inside microstructure is improved, the elastic modelling quantity is cutted down and the stuff brittleness is improved in the specified degree as well as the strength changes little.
