摘　　要：研究表明葡萄糖酸钠对混凝土有明显的辅助塑化效应,且随着掺量的增加逐渐增强;另外,在高性能混凝土中,葡萄糖酸钠与高效减水剂复配,还可提高混凝土的后期强度。葡萄糖酸钠的适宜掺量为水泥用量的0.03%～0.07%。当葡萄糖酸钠掺量超过0.1%后,由于过度缓凝使混凝土强度严重降低。It indicates that glucose-acid Na has plasticization to concrete and then preceeds to accelerate the setting of concrete with the increase of its doses.In addition, the promoting of glucose-acid Na added with the superplasticizers into HPC can highly improves the strength of concrete. The appropriate doses is 0.03%-0.07% of cement.When the doses is more than 0.1%,strength can not improve due to retard gravely.
