Concrete surface treatment process

Abstract

The invention discloses a concrete surface treatment process, and belongs to the field of building concrete. The concrete surface treatment process comprises the following steps of concrete base layerconsolidation forming, base layer outer surface grinding, concrete surface cleaning, surface primer painting, surface mortar smearing, and mortar magnetic attraction uniform layer smearing. A magnetic attraction shaping device is arranged on the side, away from the outer surface, of a concrete base layer to be machined, the magnetic attraction shaping device is started, a worker uses a mortar uniform plate for carry out smoothing on the surface layer mortar, the surface layer mortar components smeared on the concrete surface are adjusted, the surface layer mortar consolidation forming rate isimproved, meanwhile, in cooperation with the corresponding magnetic attraction shaping device, the surface layer mortar can be rapidly and flatly tiled on the concrete surface, dripping of surface layer mortar after smearing can be reduced, and the flatness of the formed concrete surface is improved.

Description

technical field [0001] The invention relates to the field of building concrete, and more specifically relates to a concrete surface treatment process. Background technique [0002] Concrete surface treatment is a method of concrete surface treatment. The concrete surface substrate has undergone weathering and corrosion, the surface is rough and porous, the surface strength is low, and there may be oil and salt pollution. The surface is covered with pores, and the pores contain water and alkaline substances. If the coating film is directly painted without treatment, not only the adhesion is poor, but also problems such as blistering, cracking, whitening and even delamination will occur. In order to avoid the above problems and prolong the service life of the coating, it is necessary to control the moisture content of the substrate and carry out correct surface treatment. [0003] In the process of common concrete surface treatment, oil removal treatment is generally carried ...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned technical scheme can well solve the problem of concrete cracks caused by the uneven surface of the concrete slab, reduce the occurrence of hidden dangers such as water leakage of the concrete slab, and the slurry collecting plate can be reused after cleaning, but the surface of the concrete is treated During the process, since the surface mortar applied on the concrete surface is in a fluid state, it needs to be shaped on the concrete surface for a period of time before it solidifies. During this time, because the concrete surface has a certain inclination angle, or the concrete surface itself is in a vertical position perpendicular to the ground Therefore, after the surface mortar is applied on the concrete surface, part of the mortar will have a tendency to drip downward under the action of gravity, and part of it will fall off from the concrete surface, resulting in a reduction in the thickness of part of the surface mortar, and even part of the mortar will gather in one place, resulting in The surface mortar is uneven, which affects the flatness of the formed concrete surface
