摘要
为了比较自密实混凝土的工作特性,首先从应用的高效减水剂和粉煤灰等掺和料及骨料等方面分析了其配制要求与机理,然后通过对自密实混凝土与加减水剂和加粉煤灰的四种混凝土进行试验,从坍落度、离析现象和强度等方面研究了自密实混凝土的主要工作性能,发现自密实混凝土与普通混凝土相比有十分明显的优越性,是未来混凝土发展的重要方向。
In this paper,for to study the workability of self-compacting concrete,first of all,the principle and demand of self-compacting concrete was found by researching the mineral materials such as superplasticizer,fly ash and aggregate.The workability of self-compacting concrete was studied by comparing concrete,self-compacting concrete,concrete mixing with fly ash and concrete mixing with superplasticizer.We found self-compacting concrete is a very important developmental direction of concrete.
