For example, the equipment foundation of heavy machinery is damaged and needs to be replaced or repaired urgently, the repair grouting of road bridge joints, the rapid grouting of high-speed railway bridge bearings, the repair of airport roads, etc., all require grouting materials with early strength and high strength. That is, it can reach more than 20MPa within 1-6h, but the patent does not give the grouting material suitable for this situation

Abstract
The invention relates to the field of cementgrout materials, in particular relating to a property-adjustable functional contraction-free cementgrout material. The contraction-free cementgrout comprises the following components in percentage by weight: 30.0%-6.0% of gelled material, 0%-5.0% of anhydrite, 4.0%-6.0% of expanding agent, 0.6%-1.5% of water reducing agent, 0%-0.09% of coagulant, 0%-2% of shrinkage agent, 0%-0.06% of thickener and 40.0%-65.0% of aggregate. The grout material has the advantages of good self-flowability, no sedimentation, no bleeding, minimum inflation and no obvious contraction phenomenon; the property of the grout material can be adjusted at random according to the requirement of a building, thus the grout material is wide in adaptability, low in cost, flexible to operate and convenient to use; and the grout material can be suitable for aid repair engineering with a high strength requirement at early period, can be used for a common grout material with a general requirement, and also can be used for a superfluid grout material with large flowability.
Description
technical field [0001] The invention belongs to the field of cement grouting materials, and in particular relates to a multifunctional non-shrinkage cement grouting material with adjustable performance. Background technique [0002] The grouting material has the characteristics of good self-flowing property, rapid hardening, early strength, high strength, no shrinkage, and slight expansion; non-toxic, harmless, non-aging, no pollution to water quality and surrounding environment, good self-tightness, and anti-rust. In terms of construction, it has the advantages of reliable quality, reduced cost, shortened construction period and convenient use. It is a material with a wide range of uses. It has been mainly used for equipment foundation grouting at the beginning, and has developed into a series of products that can be used for various purposes such as building foundation reinforcement, building reinforcement, building beams, plates, and columns. . [0003] Some people in C...
