Abstract

The invention relates to a high-performance shrinkage-free cement-based grouting material prepared by manufactured sand, which comprises the following raw materials by weight percentage: 50-60% of manufactured sand, 30-40% of ordinary portland cement, 3-6% of fly ash, 1-5% of slag powder, 0.02-0.04% of fiber, 0.1-0.14% of heavy material and 3-5% of light material. A preparation method of the cement-based grouting material comprises the following steps of manufactured sand treatment: selecting sand within three gradation ranges produced by a dry sand manufacturing system for standby, proportionally compounding and mixing components in the light material and the heavy material to obtain a mixture A, and proportionally mixing the manufactured sand, the ordinary portland cement, the fly ash, the slag powder, the fiber and the mixture A to obtain the cement-based grouting material. The cement-based grouting material has the advantages of low cost, good flowability, high uniformity, plastic micro-expansion without shrinkage, early strength, high strength and the like.

Description

technical field [0001] The invention relates to the technical field of cement-based materials, in particular to a high-performance non-shrinkage cement-based grout prepared with machine-made sand and a preparation method thereof. Background technique [0002] With the development of the construction industry and the needs of building construction, the unique properties of grouting materials have gradually been recognized and accepted by people, and its application fields have also been continuously expanded, playing an increasingly important role in engineering. [0003] Cement-based grout is a dry-mixed material composed of cement as the basic material, an appropriate amount of fine aggregate, and a small amount of concrete admixture and other materials. After mixing with water, it has the properties of large fluidity, early strength, high strength, and micro-expansion. It can be widely used in anchoring of anchor bolts, secondary grouting of equipment, and reinforcement of...
