Problems solved by technology

[0002] With the development of the wind power equipment industry, the grouting of various prefabricated beams and the grouting between the support bottom plate and the pier support pad stone put forward higher requirements for grouting materials. Imported grouting materials are expensive and have a long supply cycle. Similar products generally have low early strength, reduce construction speed, low slurry fluidity, affect working time, are not suitable for alpine environment, and cannot meet normal performance index requirements when the temperature is low, seriously affecting construction progress

Abstract

The invention relates to a high-strength anti-freeze grouting material and a preparation method thereof. The high-strength anti-freeze grouting material is prepared from the following raw materials in parts by weight: 400 to 450 parts of composite cement, 400 to 500 parts of quartz sand, 40 to 60 parts of special steel fiber, 50 to 110 parts of pulverized slag powder, 20 to 40 parts of a composite expanding agent, 1 to 3 parts of a composite early strength agent, 2 to 7 parts of a polycarboxylate water reducing agent and 0.5 to 4 parts of a defoaming agent. The preparation method comprises the following steps: guiding the composite cement and the quartz sand in corresponding prehomogenization silos for carrying out prehomogenization, carrying out continuous blending according to weight proportions, and uniformly mixing the mixed material in a forced stirring machine, thus obtaining dry powder; then guiding the dry powder in a finished product homogenization silo; electronically metering, automatically packaging into a finished product, and conveying the finished product to a finished product silo. The high-strength anti-freeze grouting material obtained through the preparation method has the characteristics of good fluidity, high strength, minimum inflation, good anti-freeze performance and no toxicity and can well adapt to operation under a high and cold environment.
