The Computer Aided Research of Redispersable Polymer Powder on Rapid Repair Mortar
The uniform design method was applied to design the experiment scheme which conformed to the restrained condition within a large range. The experiment times were reduced, the scientific and representative of the compound system was ensured. According to the conventional physical mechanical test of samples with different ratio in the designed experiment scheme, the relationship of the material composition and the property in the ternary compound system which composed of Portland cement, sulpho-aluminous cement, anhydrite was comprehensively studied. The best ratio of the inorganic adhesive material was finally determined. The influence of the ratio of the main adhesive material in repairing mortar on the strength and shrinkage property was studied using nonlinear regression analysis by SPSS (Statistical Package for the Social Science), the regression equation of the strength and shrinkage of the Portland cement, sulpho-aluminous cement and anhydrate was built, and the quantitative study of the influence factor was realized. Finally, the property from the result of uniform design for the polymer modified repairing mortar was studied.
