The cement setting time at different temperatures has been measured through choosing citric acid, sugar and sodium gluconate as the retarders of iron Portland cement.

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。
In addition, the promoting of glucose-acid Na added with the super plasticizers into HPC can highly improves the strength of concrete.

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；
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.
