Abstract
The concrete floor grinding and toughening treatment process includes initial polishing to level concrete floor, painting toughening polyester liquid, fine grinding dried floor, cleaning and other steps. In case of cracking in the floor, the cracks are first treated before initial polishing. The said treating process makes concrete floor level, smooth and well-looked, and the concrete floor has raised wear strength, antiseepage performance, oil resistance, acid and alkali resistance, and is easy to clean regularly. The present invention is suitable for concrete floor in underground park, underground emporium, exhibition hall, factory building, etc.
Description
[technical field]: the present invention relates to a kind of building field, particularly the treatment process of concrete base layer ground surface.
[background technology]: along with the development of car industry, personal car more and more enters in people's work and the life, makes underground parking (garage) obtain flourish simultaneously.Because the service condition on ground, parking lot is more abominable; the concrete surface well damage; through use after a while; ground large tracts of land be full of cracks, local founding, connectivity shrinkage crack occur through regular meeting; and ground pollution is serious; therefore have a strong impact on the overall appearance effect of engineering, and be unfavorable for daily cleaning.
[summary of the invention]: the objective of the invention is to solve existing parking lot placing and troweling concrete, problems such as large tracts of land be full of cracks, local founding, connectivity shrinkage crack appear in cement mortar surface through regular meeting, a kind of grinding and steeling treatment process for concrete substrate surface is provided.
This method may further comprise the steps:
---a, preliminary grinding: the concrete base laminar surface is ground kaiping processing;
---b, material loading: after preliminary grinding is finished the concrete base laminar surface is carried out abundant drying,, carry out drying again to the whole brushing tempering of the dried substrate surface of preliminary grinding polyester liquid;
---c, correct grinding: after treating tempering polyester liquid drying, the concrete base laminar surface is finish grinded;
---d, cleaning: behind the correct grinding, whole concrete base laminar surface is carried out cleaning promptly accuse and finish.
Though for using or not using but the concrete base laminar surface of be full of cracks, minute crack, founding occurs, before carrying out preliminary grinding, carry out crack treatment earlier: promptly at the be full of cracks or the minute crack place potting resin liquid of concrete base laminar surface, or resin liquid and cement mix and stir material, drying is carried out the substrate surface tempering again and is handled after making the resin liquid in the crack or mixing and stirring the material sclerosis.
Tempering polyester liquid wherein is monocomponent polyurethane, formulated by weight 1: 0～5 with solvent.
Advantage of the present invention and good effect: adopt the ground surface after grinding and steeling treatment process for concrete substrate surface of the present invention is handled, thoroughly solved the crack problem on ground, underground parking (garage); After milled processed, the no coating in surface, the primary colors concrete surface is smooth, smooth, and visual effect is good, surface finish maximum deviation 3mm; Has very strong adhesion stress and hardness behind the tempering curable polyester, the surface pore is filled and is reached more than 95%, improved concrete surface wear-resisting, compressive strength, oil-tight, do not seep water, not founding, no wheel roll performances such as carbon black, make daily cleaning very convenient, strengthened the aesthetic of underground garage simultaneously; Compare with epoxy self-leveling ground, have advantages such as cost is low, long service life; Pollution-free, kept concrete true qualities, belong to the environment-friendly type construction technology; The present invention is applicable to that underground concrete parking lot, large-scale underground commerce buy in the engineerings such as field, museum, industrial premises.
[specific embodiment]:
Embodiment 1
Choosing is not then come into operation as yet, and (or service time is not long, the concrete base layer ground surface of underground parking also appearance be full of cracks), at first carry out preliminary grinding: preliminary grinding can be adopted the above stone mill (getting final product as reequiping a little with the stone mill on the common ore deposit) of 150Kg, and the concrete base laminar surface is ground kaiping processing.
Material loading: with blast fan the concrete base laminar surface is carried out abundant drying after preliminary grinding is finished, after reaching the degree of drying of material loading requirement, to the whole brushing tempering of the dried ground surface of preliminary grinding polyester liquid, as monocomponent polyurethane, and being mixed with tempering polyester liquid with the ratio of the solvent that can mix 1: 0 by weight～5 with it, this example is selected 1: 5, and then carries out drying, about 15～30 hours, dry 24 hours of this example.
Correct grinding: after treating tempering polyester liquid drying, the concrete base laminar surface is finish grinded, change the mill in the above-mentioned stone mill into polishing slate, finish grind, make the concrete base laminar surface reach mute light or two kinds of different effects of light according to customer requirement with general stone grinding material.
Cleaning: behind the correct grinding, cleaning is carried out on surface entirely, pollution place that comprises the foot of a wall, post root, car lug, stop line etc. can be handed over after cleaning and finishing.
Embodiment 2
Select a place to use and occur chapping or the concrete base laminar surface of minute crack, before carrying out preliminary grinding, carry out crack treatment earlier: promptly at the be full of cracks or the minute crack place potting resin liquid of ground surface, after the dry resin liquid sclerosis that makes in the crack in 24 hours, carrying out the ground surface tempering again handles, see embodiment 1 for details, tempering polyester liquid wherein is monocomponent polyurethane, formulated by weight 1: 3 with solvent.
Embodiment 3
Select a place to use and concrete base laminar surface occurs than wide seam (or founding is more serious), before carrying out preliminary grinding, carry out crack treatment earlier: the material that mixes and stirs of promptly locating potting resin liquid and cement in the crack of ground surface, after drying makes mixing and stirring in the crack expect sclerosis, carrying out the ground surface tempering again handles, see embodiment 1 for details, tempering polyester liquid wherein is monocomponent polyurethane (weight of solvent selects 0).
Comparative Examples:
Adopt concrete base layer acierage treatment process of the present invention and do not adopt the ground performance contrast of science and engineering skill herein, see the following form:
