Description

Sand washing color concrete floor manufacturing process

Technical Field

The invention relates to the technical field of ground manufacturing processes, in particular to a sand washing color concrete ground manufacturing process.

Background

One of the methods of the existing process for manufacturing water-washed stone ground is to use water-washed stone to construct the road surface, the selected sand and stone are mixed with cement and adhesive, then the treated raw materials are laid on the road surface, and sponge or water is used for washing when the road surface is semi-dry until the cement laitance is washed clean and the sand and stone are completely exposed. After the final setting is reached and the curing period is reached, a surface layer protective agent is coated on the surface in a rolling mode. During construction, the temperature is not required to be too high, so that the concrete slurry is prevented from being quickly coagulated and is not suitable for washing surface laitance. Therefore, the method is greatly influenced by weather and temperature, large-area construction is not suitable, the working efficiency is low, and the labor cost is not suitable to be saved. The uniformity of sand and stone washing and the flatness of the ground are difficult to control; it is difficult to make some complicated and rich patterns or fine sand texture effects.

Another method for manufacturing the water-washed stone floor is to use oxalic acid to wash the colored concrete floor 10 to 15 hours after the initial setting. However, this method also has a problem of being affected by the weather temperature. And the color of the colored concrete ground becomes darker as the oxalic acid corrodes the color of the colored concrete. This method makes it difficult to control the degree of uniformity of the brushing. Oxalic acid is colorless and odorless, is easy to volatilize into gas in the acid washing process, can destroy respiratory mucosa of people if being inhaled into the body by people, can also damage peripheral soil plants, and is not beneficial to health and environmental protection.

Disclosure of Invention

The invention aims to provide a process for manufacturing a sand washing color concrete ground, which can solve the problems that the surface effect of sand washing is difficult to control, sand washing stone particles are not uniform or the surface effect of uniform tiny stone particles cannot be washed when a large-area sand washing color concrete ground is constructed. The purpose of the invention is realized by the following technical scheme:

a sand washing color concrete ground manufacturing process comprises the following steps:

s1, cleaning the ground of the site base layer, and paying off to control the elevation of the site;

step S2, carrying out formwork division of the color concrete ground, paving reinforcing mesh or reinforcing steel bars at the crack, and placing cushion blocks;

step S3, pouring surface color concrete, vibrating and leveling, and trowelling and smoothing;

step S4, when the color concrete reaches final setting, covering the film attached with the retarder on the surface of the color concrete, with the retarder facing downwards, and standing for a period of time;

step S5, uncovering the film, and uniformly washing away the cement laitance of the delayed hydration reaction after the retarder acts on the surface of the colored concrete by using a high-pressure water gun;

s6, after the maintenance period is reached, paying off the expansion joint, and starting to cut the expansion joint;

and step S7, cleaning the ground, rolling and coating a sealing agent on the surface layer, and pouring and sealing the split-bin structure joint.

Further, in step S2, when special sand granule effect is required, the sand granules are spread uniformly in the longitudinal and transverse directions, and then troweling and polishing are performed again.

Further, in the step S4, the standing time is generally 12 to 18 hours.

Further, in step S6, the curing period is continued for at least 7 days.

The process for manufacturing the sand washing colored concrete ground can utilize the retarder to print the film with patterns to manufacture more abundant and diversified customizable regular patterns or abundant light and shadow images, and can utilize the film paper with the retarder to manufacture the abundant and colorful ground surface texture effects (such as the corrosion effect of seaside porous stones and the moth-eaten weathering effect). The sand washing color concrete ground manufacturing process can well control the sand washing surface effect when large-area sand washing color concrete ground construction is carried out. The construction method can be used for large-area construction, the construction efficiency is improved, the construction period is shortened, the construction difficulty and the labor intensity are reduced, and the engineering cost is reduced. The materials and the additive used in the invention meet the requirements of energy conservation and environmental protection and are harmless to human bodies.
