Embodiment 1

[0032] Clean the cracks in the building wall with a width of 1cm and a depth of 3cm to be treated, clean up the gravel and floating ash in the cracks, and make the cracks in the wall into a more regular V-shaped groove shape to facilitate repair. Mix component A and component B of art molding clay according to the weight ratio of 1:1, the component A is epoxy resin, and the component B is curing agent; after mixing evenly, in the mixture Add filler, wherein the weight ratio between the mixture of component A and component B and the filler is 1:2; and add white coloring material accounting for 5% of the total weight of art molding clay to obtain soft white art Forming sculpture clay. The curing agent is an ethylenediamine curing agent. The prepared art sculpture molding mud is covered with both sides of the crack, then the entire crack is filled, and finally the surface is compacted and smoothed. After repairing the cracks, the art molding clay is well combined with the wall,...

Embodiment 2

[0034] Clean the cracks in the building wall with a width of 2cm and a depth of 4cm to be treated, clean up the gravel and floating ash in the cracks, and make the cracks in the wall into a more regular V-shaped groove shape to facilitate repair. Mix component A and component B of art molding clay according to the weight ratio of 1:1.5, the component A is epoxy resin, and the component B is curing agent; after mixing evenly, in the mixture Add filler, wherein the weight ratio between the mixture of component A and component B and the filler is 1:3; and add white coloring material accounting for 3% of the total weight of art molding clay to obtain soft white art Forming sculpture clay. The curing agent is an ethylenediamine curing agent. The prepared art sculpture molding mud is covered with both sides of the crack, then the entire crack is filled, and finally the surface is compacted and smoothed. After repairing the cracks, the art molding clay is well combined with the wal...

Abstract

The invention discloses a method for repairing cracks of building walls. According to the method for repairing cracks of building walls, art sculpture forming clay is used for repairing cracks of building walls. The method comprises the steps of A, cleaning cracks to be processed; B, preparing the art sculpture forming clay; and C, filling cracks with the prepared art sculpture forming clay. According to the method, the art sculpture forming clay substitutes for ordinary wall crack repairing agents, characteristics of the art sculpture forming clay, such as the adhesiveness, the solidification forming and anti-seepage performance and the cracking-free performance, are used, and colors of the art sculpture forming clay can be adjusted conveniently to be consistent with colors of surrounding walls, so that the good repairing effect can be achieved, and the whole repairing process is simple, fast and effort-saving. The method develops a new application of the art sculpture forming clay.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for repairing cracks in building walls. Background technique [0002] Due to its high brittleness, concrete structures often crack inevitably in engineering applications. Such cracks lead to the decrease of water tightness and leakage of concrete structures, which affect the service life of the project, and even cannot be used normally. At present, the traditional method of repairing concrete cracks is to use water-based adhesives to adjust cement repairs, but it is difficult to meet the current repair standards for anti-leakage, and has been gradually eliminated. In recent years, when the proportion of the two components is strictly appropriate, the repairing agent of organic polymers used more in recent years can achieve the effect of anti-leakage. It is difficult to deploy evenly, so that the repairing agent prepared cannot achieve its anti-leakage repairin...
