Starting with the analysis of the relations between the composition materials and the workability, strength and shrinkage of the self-compacting concrete, the thesis studied the effect of the water to binder ratio, mineral admixture content, aggregate volume content etc. on the workability, strength and shrinkage performance of medium strength self-compacting concrete, analysed the mutual relationship between the concrete shrinkage and the free water loss rate, hydration degree of the corresponding c...
