Abstract

The invention discloses a water-based capillary crystalline type concrete surface layer repairing and reinforcing material as well as a preparation method and application thereof. The material comprises 48-60 parts of lithium silicate, 20-28 parts of potassium silicate, 24-30 parts of sodium silicate, 2-10 parts of organosilicon, 0.5-2 parts of a coagulant, 0.8-1.8 parts of a waterproof agent, 0.1-0.25 parts of a surfactant, 0.2-1 part of a reaction retarder, 0.1-0.24 parts of an anti-freezing agent, 0.6-1.2 parts of fluosilicate, 0.1-0.2 parts of an antifoaming agent, 0.08-0.16 parts of a multifunctional auxiliary agent, 0.5-2 parts of an early strength agent and 95-115 parts of water. The water-based capillary crystalline type concrete surface layer repairing and reinforcing material hasthe characteristic of quick strength improvement, has an obvious repairing effect on concrete and mortar, and can repair and heal cracks and fine cracks, so that the water permeability resistance ofthe concrete can be improved. The water-based capillary crystalline type concrete surface layer repairing and reinforcing material is good in durability, long in service life, simple and convenient toprepare and convenient to construct.

Description

technical field [0001] The invention relates to building materials for concrete, in particular to a water-based permeable crystalline concrete surface repair reinforcement material and a preparation method and application thereof. Background technique [0002] Compared with the concrete interior, the surface concrete is at a disadvantage during the preparation process and after forming. In the process of concrete preparation, the "wall effect" of the formwork-concrete interface and the bleeding of the upper surface of the concrete cause local high sand ratio, high lime-sand ratio and local high water-cement ratio, and the release agent on the formwork often makes the concrete surface The hydration of cement is hindered. When the concrete is in a dry environment and the curing conditions are insufficient, the unfavorable conditions such as insufficient cement hydration caused by insufficient curing due to surface water loss cause the surface density and strength of the concr...
