Concrete surface sand blasting process

Abstract

The invention discloses a concrete surface sand blasting process, which is characterized by comprising the following steps of base layer cleaning: before the sand blasting, dust on the wall surface of the base layer needs to be firstly cleaned; small holes are repaired; and if a release agent exists on the surface of the base layer, the release agent needs to be cleaned up and brushed by a steel wire brush; wall surface moisturizing: after the base layer is cleaned up, the wall surface is sufficiently wetted through water spraying, and the depth is about 3mm; and the wall surface needs to be in an inner wet state before the sand blasting; material preparation: a sand blasting material needs to be prepared according to the mixture ratio of powder to sand being 1 to (1.5-2.0); a special sand blasting glue is added; and the mixture is uniformly stirred; sand blasting construction: the pressure of an air compressor during the construction is not smaller than 8MPa; and maintenance. The sand blasting process has the advantages that the steps are simple; many repeated work procedures are omitted; and the work efficiency is improved.

Description

technical field [0001] The invention relates to a concrete surface sand blasting process. Background technique [0002] Sandblasting is a new construction technology for concrete surface treatment. It is mainly used to solve the common quality problems of empty plastering and easy cracking on the wall, and to increase the appearance of the living surface. The sandblasting process uses the pressure of the air compressor to spray the specially prepared slurry onto the surface of the concrete base to form a uniform surface. After a certain period of maintenance, the dots can reach the ideal strength, thereby increasing the bonding force between the base layer and the plastering layer, and achieving the purpose of preventing hollowing and cracking. [0003] At present, the sandblasting process on the concrete surface is complicated, and there is no uniform standard, resulting in uneven quality of the sandblasting process. Many repeated processes also make the production efficie...

Problems solved by technology

[0003] At present, the sandblasting process on the concrete surface is complicated, and there is no unified standard, resulting in uneven quality of the sandblasting process. Many repeated processes also make the production efficiency low, increase the labor burden of workers, and make the product's market competitiveness not high.
