Pumping agents are added in the laboratory experiments to improve the poor fluidity of the paste. The influences of five different kinds of pumping agents on the flow properties are investigated by comparing the slumps and the slump flow. The result of test shows that the pumping agent C has the greatest effect with the best adding range of 2.0%-2.5%. The fitting result of the uniform design shows that the concentration and the aggregate ratio tail are negatively correlated with the liquidity and the sand-cement ratio is positive. Based on the fitting equation, the recommended mixing proportion of the paste is derived: The concentration of 77.5%- 78.5%, the aggregate ratio of 4.5-5.5, the amount of the pumping agent of 2.0% (quality of the cement), the sand-cement ratio of 8. The results of the confirmatory experiment show that the actual requirements are met.
