    Abstract：By means of the investigation of effects of polymerization conditions，like polymerization temperature and Al2（SO4）3 concentration，and stabilizer proportion，like lactic acid and triethanolamine，on the synthesis and stability of polyaluminium sulfate，the optimum synthetic parameters of polyaluminium sulfate were defined. Furthermore，high quality non-alkali coagulant setting accelerator CS-A with excellent stability and outstanding coagulating effect was produced. In addition，the adaption inquiry respected to performance was applied to commercial cement，and showed excellent effect.
