Polymer cement-based high-performance grouting material and preparation method thereof
The invention discloses a polymer cement-based high-performance grouting material, which comprises a cementing material component, an aggregate component, an additive component and water, and the cementing material component comprises 75-90 parts of Portland cement, 5-10 parts of special quick-hardening cement and 3-8 parts of micro-silica fume; the aggregate component is prepared from 25 to 35 parts of coarse sand, 15 to 30 parts of fine sand and 10 to 15 parts of superfine mineral filler; the additive component comprises 0.35-0.4 part of a water reducing agent, 0.04-0.08 part of an expanding agent, 0.003-0.006 part of a polymer thickening agent, 0.3-0.8 part of a polymer adhesive and 0.12-0.18 part of a defoaming agent, the ratio of water to materials is 0.18-0.2, the Portland cement can be 425 # Portland cement, 425 # ordinary Portland cement and 425 # composite Portland cement, preferably, the 425 # ordinary or composite Portland cement. The invention provides a polymer cement-based high-performance grouting material by researching and developing a combined material of a superfine mineral filler and a polymer thickener, adopting a scheme of combining special quick-hardening cement with a specific water-binder ratio and introducing a novel expanding agent and a polymer adhesive.
