Prestressed pipeline grouting material and preparation method thereof
The invention provides a prestressed pipeline grouting material. The material comprises the following components in percentage by mass: 50-77% of cement, 10-20% of steel slag micro-powder, 5-10% of zeolite powder, 5-15% of grinded rice hull ash, 2-9% of expander, 0.3-1.5% of powdery high-performance water reducer, 0.02-0.04% of defoamer and 0.02-0.06% of retarder. The invention further provides a preparation method of the material simultaneously. The scheme provided by the invention is used for solving the defects in the prior art; steel slag micro-powder, zeolite powder and grinded rice hull ash are used in the material as admixtures; the problems of shrinkage and bleeding are solved by comprehensively utilizing the advantages of the various admixtures, and the durability of the grouting material is improved; meanwhile, the steel slag, zeolite and rice hull ash resources are greatly utilized.
