What is the construction process of wear resistant concrete floor, and what is the practice of wear

Do the math how much it will cost you to renovate your home

The construction is divided into two parts, the construction is different, the specific construction technology will be different, as follows:

1) Construction technology of spraying concrete sealing curing agent on the surface of concrete

1. Polishing the ground with water to clean up the remaining stains on the ground.

2. Flush the ground and clean up the dirt and dust on the concrete floor.

3. Use a siphon to suck off the residual sewage on the ground.

4. Clean the ground.

5. Spray concrete sealing curing agent on the ground.

6. Use tools to polish the ground.

2) The construction technology of the wear-resistant floor:

After the initial setting of the base concrete, the aggregate is evenly sprinkled on the ground surface in two times, and the amount of sprinkling needs to be ensured each time.

1. Sprinkle aggregate on the ground for the first time, and the amount of aggregate sprinkled should not exceed two-thirds of the total amount, and the aggregate needs to be compacted and rubbed with a polishing disc.

2. Sprinkle aggregate on the ground for the second time, and the amount of aggregate sprinkled should not exceed one-third of the total amount, and the aggregate needs to be compacted and rubbed with a trowel disc.

3. After the ground is initially set, use a calender to wipe the ground several times.

4. When sprinkling and grinding the ground, it is necessary to check in detail whether the sprinkling aggregate is smooth, and for low-lying places, it is necessary to adjust the sprinkling method and the amount of sprinkling in time.

5. Before the construction is completed, it is also necessary to use a trowel to collect light on the ground, so that the color on the ground is not kept dense and uniform.

6. After the construction is completed, sprinkle some water on the ground within four to six hours, or spray some curing agent, so as to ensure that the strength of the ground wear-resistant floor can rise steadily.

First: make concrete sealing curing agent on top of concrete.

Construction process: clean the ground.

Bring water to polish and decontaminate.

Wash the floor. Siphon sewage to clean the ground.

Spray concrete sealant curing agent.

Ground polishing. Second: make a wear-resistant floor on top of the poured concrete.

Construction technology: when the base concrete is initially set, the aggregate is evenly spread, and the sprinkling is carried out in two times, and the dosage is guaranteed;

1. 2 3 of the total amount of the first spreading, compacted and rubbed with a polishing disc;

2. 1 3 of the total amount of the second spreading, compacted and rubbed with a trowel disc;

3. After the initial setting, wipe it with a calender for many times;

4. When sprinkling and grinding, the flatness of the sprinkling should be checked, and the low-lying places should be adjusted in time;

5. Before completion, use a trowel for light collection to achieve uniform and dense surface color;

6. Base surface curing: within 4-6 hours after the completion of construction, the wear-resistant hardened floor should be cured with clean water or curing agent on the surface to ensure the stable growth of the strength of wear-resistant materials;

Wear-resistant concrete floor is one of the most common grounds, which not only has wide applicability, but also is simple and convenient to construct, so it is favored and liked by everyone. So what is the practice of wear-resistant concrete flooring? What are the precautions for wear-resistant concrete floor construction?

First of all, the ground is cleaned, the ground is leveled, and the aggregate is evenly sprinkled when the leveling layer is not dry. Secondly, the corners are reinforced, the ground is sanded, and then the concrete is sawed at the appropriate position, the expansion joints are made, and the caulk is filled. Finally, it is rolled with transparent sealant, trowel smoothed, and then polished, receiving, curing and other processes.

Precautions for wear-resistant concrete floor construction:

1. The wear-resistant concrete surface layer should be paved with HS series wear-resistant fabrics.

2. Wear-resistant fabrics are made of cement and composite reinforcing agents, and are laid with a combination of metal materials and natural hard minerals with wear-resistant aggregates, which have a variety of functions such as high wear resistance, high strength, impact resistance, no dust and no penetration.

3. Wear-resistant concrete is used in industrial plants, warehouses, parking lots, tunnels, docks and other places.

Fourth, the wear-resistant concrete ground construction should meet the following requirements:

1. Wear-resistant fabrics should be selected from HS series products.

2. The thickness of the wear-resistant concrete surface layer is generally 10 15mm, but it cannot be greater than 30mm, and the error cannot be greater than IMM.

3. Before construction, the construction plan should be formulated and the construction equipment should be prepared.

4. When the surface layer is laid on the cement concrete cushion, the thickness of the cushion cannot be less than 50mm. If there is a large impact, it is necessary to add anti-crack reinforcement mesh to the cushion, generally using 4@150 200mm two-way grid, and to be placed in the upper part, and its protective layer is controlled at 20mm.

5. If there are requirements for cleanliness and beauty, the color wear-resistant concrete surface layer should be used.

6. The temperature of the construction environment shall not be lower than 5.

7. The amount of water added to the laying of wear-resistant concrete fabrics should be adjusted according to the dryness and wetness of the concrete, and the fabrics can be used when mixed evenly with water to control the construction progress.

8. The wear-resistant concrete surface layer should be carried out by smashing and wiping.

Article summary: Well, what is the practice of wear-resistant concrete ground and the relevant knowledge of wear-resistant concrete ground construction precautions are introduced here, friends who need more information, please continue to pay attention to Qeeka Home, and we will have better and more exciting content for you in the future.

In terms of decoration, floor paint is also relatively common, and it is generally used in large venues, such as parking lots, large factories, etc., so do you know the wear-resistant floor paint? As the name suggests, it is a little more wear-resistant than the ordinary one, thenWear-resistant floor paint construction technologyWhat are they? What are the key points of wear-resistant floor paint construction that we need to pay attention to?

Let's introduce it to you.

1. Wear-resistant floor paint construction technology

1. The construction of wear-resistant flooring needs to fully communicate with the concrete pouring party in advance, and Tuanying clarifies the construction scope and daily engineering quantity, and clarifies the floor color in different areas; Prepare workers, trowels, hand tools, gasoline and other materials according to the daily planned amount of work, and set aside a margin;

2. The construction site should be sheltered from wind and rain, with sufficient lighting at night, complete water and electricity, to ensure that the construction site has cement concrete pouring and wear-resistant floor construction conditions, and avoid cross construction;

Thick C20 concrete, equipped with two-way steel bars, and the spacing of steel bars is set at 120mm, in order to prevent large-scale cracks and settlement on the ground. The concrete is polished as it is beaten.

4. After the concrete base has a certain strength, the construction of the thick SY-PET waterproof membrane moisture-proof layer can be carried out. First, the base layer is wet, the cement adhesive is configured, and the base layer is directly applied after stirring evenly, and then paved in the established order, and the complex parts and corners should be strengthened.

Second, the main points of wear-resistant floor paint construction

1. During the construction of ground treatment floor paint, first remove the cement slurry on the surface and the adhered garbage and debris; The hairing of the floor surface needs to be completed with a grinder and thoroughly cleaned; The position that the grinder cannot grind under the machine equipment needs to be cleaned with a steel brush; The part of the ground that has oil stains needs to be cleaned by special methods; Apply putty to the holes and obvious depressions on the surface of the floor to fill the batch scraping, and after drying, polish and vacuum.

2. The ambient temperature of the construction site should be higher than 5, and the relative humidity should be less than 85% before construction. The builder should make practical records of the construction site, time, temperature, relative humidity, floor surface treatment, and data for repressing. After the coating is applied, the relevant equipment and things should be cleaned immediately.

3. The primer construction is to treat the clean and flat surface of the plain ground, and the penetrating solvent-based epoxy resin primer material is used to seal and coat it in batches; The primer material has strong permeability, can penetrate into the base layer, enhance the adhesion of the coating and the base layer, and its coating must be continuous, without interruption, and the coating amount is subject to the saturation of the surface. Refer to CNS8083 and require more than 25kgf cm2.

Wear-resistant floor paint is also more common in decoration, we often see it in the underground parking lot, so what are the key points that need to be paid attention to in the construction process of wear-resistant floor paint and it, and you have also understood it through the introduction.
