Problems solved by technology

At present, the general practice of this kind of anti-slip pavement is to use single (double) component organic gelling materials, aggregates, and additives for paving. The volatility of organic substances in organic materials will be restricted by environmental protection. The weather resistance is not good, especially in the outdoors, the color will fade after a long time, and under the condition of repeated dry and wet cycles outdoors, its adhesive performance will deteriorate and it will fall off

Embodiment 1

[0031] The paving process is as follows:

[0032] Remove floating ash and oil stains on the surface of the original concrete base, repair surface holes and cracks, and then apply 1-2 times of acrylic emulsion interface agent; weigh anti-cracking cement, shrinkage-reducing reinforcing agent, bentonite, silicon Ash, wear-resistant aggregate, pigment, titanium dioxide, retarder, water reducer, redispersible latex powder, cellulose ether, calcium formate, waterproofing agent, and mix well; add water in specified proportion to the above dry powder mixture, Stir for 5 minutes until the slurry is uniform without agglomeration, let it stand for 1 minute, and then stir for 1 minute to start paving construction; spread the stirred slurry evenly on the wet ground to ensure that the paving thickness reaches 10 mm. Then use the brushing roller to brush once as a whole to get a uniform rough surface; after the paving is completed, it must be cured for 24 hours before it can be opened for tr...

Abstract

The invention provides a high-viscosity non-shrinkage cement-based matte flooring material and a paving process thereof. The flooring material includes the following components in percentages by weight: 30%-38% of Portland cement, 4%-12% of a shrinkage enhancing agent, 0-5% of bentonite, 1%-2% of silica fume, 45%-60% of a wear-resistant aggregate, 0.5%-1% of a pigment, 1%-2% of titanium dioxide, 0.2%-0.4% of a retarder, 0.02%-0.05% of a water reducing agent, 1%-2% of redispersible latex powder, 0.1%-0.2% of cellulose ether, 0-1% of calcium formate, and 0.2%-1% of a waterproofing agent. According to the process, the wear-resistant aggregate with a certain fineness and the functional additives are added into the cement-based material, and through the mutual synergy of the raw materials, theprepared flooring material has excellent crack resistance, strong adhesion, wear resistance, slip resistance, weather resistance, water resistance and seepage resistance, and has a simple and fast construction process.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a high-viscosity non-shrinkage cement-based frosted ground material and a paving process thereof. Background technique [0002] With the development of the city, the safety, aesthetics, and durability of urban pavement have become the basic requirements for the development of urban pavement, especially for pedestrian ramps, overpasses, and entrances and exits of underground parking lots. In rainy and snowy weather, this kind of pavement needs to be durable Grinding anti-skid function. At present, the general practice of this kind of anti-slip pavement is to use single (double) component organic gelling materials, aggregates, and additives for paving. The volatility of organic substances in organic materials will be restricted by environmental protection. The weather resistance is not good, especially in the outdoors, the color will fade after a long time, and under the condition ...
