摘要：

The influence of mixed air-entraining admixture in superplasticizer to concrete drying shrinkage and early shrinkage and cracking performance has been investigated in this text according to flat shrinkage cracking and criterion drying shrinkage method. The results indicate that: the SJ-2 air-entraining admixture mixed in superplasticizer appropriately will enhance the tensile strength and improve the concrete performance to resist shrinkage and cracking. The water-reducing function and dosage should be regarded in air-entraining admixture's using process, in this condition, the concrete strength and function to resist shrinkage and cracking can be enhanced with the same workability.
