Abstract : 　This text contrasts the admixture experiment of first admixing method and latter admixing method. At last ，the second method was applied and solved the problem that slump loses quickly and the problem that admixture and cement are not suitable for each other.

Key words : 　the loss of slump　first admixing method  　latter admixing method
