Abstract

The invention discloses a building high-strength grouting material. The building high-strength grouting material is prepared from, by weight, 44 parts of Portland cement, 33 parts of silver sand, 5 parts of fiber mixture, 4.5 parts of superfine slag powder, 2 parts of expanding agent, 1.5 parts of water reducing agent, 2 parts of defoaming agent, 3 parts of organic silicon microspheres, 4 parts ofglass beads and 1.2 parts of tetraethylenepentamine. The building high-strength grouting material is good in heat preservation and physical strength performance and high in compressive strength and breaking strength and has the high practical value and the good application prospect.

Description

technical field [0001] The invention relates to the technical field of grouting materials, in particular to a high-strength building grouting material 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. Grouting materials are based on high strength The material is used as aggregate, cement is used as binder, and supplemented with high fluidity, micro-expansion, anti-segregation and other substances. It can be used after adding a certain amount of water at the construction site and stirring evenly. The grouting material has good self-flowing properties, rapid hardening, early strength, high strength, no shrinkage, and slight expansion; it is non-toxic, harmless...
