Problems solved by technology

[0003] Because the surface cleaning agent is artificially sprayed, it is inevitable to be thick or thin; or due to various factors such as temperature, the setting time difference is not well grasped, resulting in a late flushing time; or when the corners and seams are not covered tightly when covered with plastic film, these factors It will cause part of the surface cement slurry to solidify, and the washing will not be clean, and there will be residue
This will not only affect the water permeability of the concrete but also affect the appearance
However, there is no good way to deal with the residual cement slurry

Abstract

The invention relates to a special modification agent for the surface of exposed aggregate permeable concrete, and belongs to the technical field of chemical cleaning products. The special modification agent for the surface of the exposed aggregate permeable concrete, disclosed by the invention, is prepared from the following components in percentage by weight: 30-60% of an acid solution, 15-35% of a viscosity regulating agent, 3-8% of a stabilizing agent, and 10-30% of water. The special modification agent for the surface of the exposed aggregate permeable concrete is low in cost, safe and convenient to use, the removing time of solidified cement paste on the surface of the exposed aggregate permeable concrete is short, and the permeable effect and the apparent effect of concrete are improved.

Description

technical field [0001] The invention relates to a special correction agent for the surface of permeable concrete exposed to aggregate, and belongs to the technical field of chemical cleaning products. Background technique [0002] As a new type of green and environmentally friendly material, permeable concrete with exposed aggregate is more and more used in landscape gardens because of its air-permeable surface "skin breathing" function and the natural and unique visual beauty brought by exposed stones on the surface. and other leisure places on the road. During the construction process of exposed aggregate permeable concrete, the mixed permeable concrete needs to be spread, leveled, vibrated, and pressed. After the treatment is completed, the surface cleaning agent should be sprayed immediately and covered with plastic film, so that the surface concrete and internal concrete can be produced. The setting time is poor, that is, the lower concrete has reached the final settin...
