Special correction agent for exposed aggregate pervious concrete surface and smearing method of correction agent

Abstract

The invention discloses a special correction agent for an exposed aggregate pervious concrete surface and a smearing method of the correction agent, belongs to the field of concrete correction agents,and discloses the special correction agent for the exposed aggregate pervious concrete surface and the smearing method of the correction agent. The correction agent comprises the following components: an acidic solution (oxalic acid, dilute sulfuric acid or dilute hydrochloric acid), a viscosity regulator (xanthan gum, honey, maltodextrin or acidity regulator), a stabilizer (an emulsion delamination inhibitor EE, a beverage special stabilizer JJKW004 or a liquid suspension stabilizer SF-1) and water. A brush can be electrically driven to be matched with the correction agent to quickly wipe and brush a concrete wall; the correction agent is uniform in wiping and brushing, high in efficiency, capable of reducing labor intensity, capable of meeting the wiping requirements of concave surfacesand planes in cooperation with flexible movement of the movable disc, capable of guaranteeing uniform wiping and brushing of the correction agent of various wall forms, easy to operate and high in flexibility; a partition plate is arranged in a storage box, clear water is sprayed to flush the wall, and the wiping and brushing effect of the correction agent is further improved.

Description

technical field [0001] The invention relates to the field of concrete modifiers, in particular to a special modifier for the surface of permeable concrete with exposed aggregates and a coating method thereof. 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. On the pavement of leisure places, the permeable concrete with exposed aggregate needs to be spread, leveled, vibrated, and pressed during the construction process. After the treatment, the surface cleaning agent should be sprayed immediately and covered with plastic film, so that There is a difference in setting time between the surface concrete and the internal concrete, that is, the lower concrete has reached the final setting state, but the surface ...

AI Technical Summary

Problems solved by technology

[0003] At present, the application of the special correction agent on the exposed aggregate permeable concrete surface is to manually use the roller to pick up the correction agent to brush the wall. Due to the unevenness of manual wiping, the wiping effect is not good and the labor intensity is high. Different for depressions and planes For the walls of the environment, the effect of roller scrubbing is limited, and the correction agent cannot be applied evenly. After scrubbing, the wall needs to be rinsed with the help of additional equipment. The steps are cumbersome and the operation is complicated.
