Problems solved by technology

However, the chemical slurry whose main component is epoxy resin has the following disadvantages: Due to the resin's high oil absorption rate for sodium silicate, the sodium silicate is absorbed instead of filling into the crack or cavity area, so that it cannot perform out of the original function as a filler, and the strength of the slurry is reduced, and the adhesion between the cracks is reduced, resulting in the re-formation of cracks
[0013] Moreover, the current repair and reinforcement methods for structures are complicated, it takes a long time to restore the original shape, the restoration effect of the damaged appearance is not good, and re-cracking often occurs
[0014] In addition, when grout needs to be filled into a cracked area that is opposed to gravity, such as the top of a building, the existing grout flows out from the filling position, so it is difficult to use them for construction, and performance cannot be guaranteed

Embodiment 1

[0093] Evenly mix 1 kg of liquid epoxy resin, 1 kg of glass powder having an average diameter of 200 mesh and a specific gravity of 2.54, 300 g of glass beads with an average diameter of 0.1 mm as filler, 50 g of NaCl as an alkali metal compound or alkaline earth metal compound, and 300 g Solvent, from which the main ingredient is prepared.

[0094] Next, 500 g of aluminum powder, 300 g of glass beads having an average diameter of 0.1 mm as a filler, and 400 g of an epoxy hardening agent were uniformly mixed, thereby preparing a hardener.

[0095] The foaming chemical paste is prepared by mixing the above-prepared main ingredients and hardener.

Embodiment 2

[0097] According to the same method as in Example 1, the main component and the hardener were mixed to prepare a foamed chemical slurry, except that 100 g of ground glass fibers having an average fiber diameter of 13.5 μm and an average fiber length of 300 μm were added to Example 1. 1 in the principal component.

Embodiment 3

[0099] According to the same method as Example 1, mix the main component and hardener to prepare foaming chemical slurry, the difference is to use calcium carbonate (CaCO 3 ) to replace the glass beads of Example 1 as filler.

Abstract

The present invention relates to a foaming chemical grout, particularly a foaming chemical grout comprising an epoxy resin (based on solids), a glass powder, a filling agent, an alkali metal compound or alkali earth metal compound, a metal powder, a hardening agent and a solvent. And it also relates to a method for the construction, repair or reinforcement of a structure which is characterized in that the foaming chemical grout is used. The foaming chemical grout in accordance with the present invention has excellent filling performance in upper sides against gravity, especially crack and eroded cave regions having counter direction against gravity like ceilings due to its excellent foaming ability when injected and foamed, has high-intensity, closed pore structures thereby resulting in excellent filling effects even in places subject to pressure or load, has excellent adhesion and working per not formances thereby enabling single process without requiring additional processes even in wet and aquatic environments, and is easy and simple to operate thereby having excellent effects on the construction, repair and reinforcement of a structure.

Description

technical field [0001] The present invention relates to a foamed chemical grout, and more particularly, the present invention relates to the following foamed chemical grout and methods for constructing, repairing and reinforcing structures using the foamed chemical grout: due to the foaming The chemical slurry has excellent foaming ability when injected and foamed, so the foamed chemical slurry has excellent performance on the upper side against gravity, especially in the top and other cracks and cavity areas that are opposite to gravity. The filling performance; the foamed chemical slurry has a high-strength closed-cell structure, which can produce an excellent filling effect even where it is subjected to pressure or load; the foamed chemical slurry has excellent adhesion and handling properties, so that the operation can be completed in one step even in a wet and watery environment without additional steps; moreover, the foamed chemical slurry is easy to operate, thereby hav...
