| Abstract: | The effect of different species of gypsum on water reducing agent/cement binary system was formerly studied by experiment.The subsidiary plasticizing mechanism of different species gypsum and the retarder agent with high efficiency water reducing agent\ retarder agent\cement ternary system was studied by the cement paste experiment(the loss of the paste fluidity and the elapsed paste fluidity were tested)in the paper.The self-grinded cement,the high efficient naphthalene water reducing agent and the retarder agent such as trimeric sodium phosphate,sodium gluconate,sodium hexametahposphate,citric acid and white sugar were used in the paper. |

| Keywords: | gypsum retarder agent high efficient water reducing agent subsidiary plasticizing mechanism subsidiarywater reducing ratio |
