Problems solved by technology

[0002] During the ground construction process, the ground is prone to cracks due to factors such as construction schedule, construction procedures, and seasonal construction. Finished, without doing a second wipe
After the ground is cracked, it is easy to have various quality problems such as sanding and surface layer falling off, which will eventually affect the normal use of the ground. According to the conventional repair method: during the construction period, it takes a long time to seal the repaired ground, and the area to be chiseled during maintenance is relatively small. Large, the ground after maintenance is easy to crack, and the rework rate after maintenance is generally high. These problems hinder the development of the construction industry

Abstract

The invention discloses a high-strength repairing material for concrete cracks. The high-strength repairing material comprises the following raw materials in parts by weight: 40-50 parts of ground waste concrete powder aggregate, 6-8 parts of fine sand, 20-25 parts of polyvinyl chloride ethyl ester, 8-10 parts of gypsum powder, 10-15 parts of a resin curing agent and 15-20 parts of water. A construction method of the high-strength repairing material for the concrete cracks comprises the following construction steps: (1) preparing the repairing material; (2) cleaning the cracks; (3) preprocessing the cracks; (4) filling the cracks; and (5) carrying out maintenance. The high-strength repairing material has the advantages that the raw material source is wide, the economic cost is low, the connection strength is high, the cracking is avoided, and the construction is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a high-strength repair material for concrete cracks and a construction method thereof.
