How to do plain cement flooring? How to do industrial wind cement floor

Cement floor is divided into the following two types according to the different materials used: 1. Cement bean stone floor, the main material is cement, bean stone (particle size is 3 6mm), and the mix ratio of cement: bean stone is 1:

2. The water-cement ratio is 20mm thickness; Cement mortar floor, the main material is cement, medium sand or coarse sand, mix ratio cement: medium sand or coarse sand is 1: or 1:

2. Thickness 20mm, mortar consistency.

Construction method: 1. First clean the base chisel and debris, and water and moisten, brush 1 cement slurry; 2. Spread out the cement bean stone or cement mortar, and level it with aluminum alloy fang; 3. After flattening, the pat is compacted, and the surface layer is calendered; 4. Sprinkle sawdust on the surface for at least 7 days, and water at least once a day according to the situation.

In order to achieve no ash, no peeling, and not easy to crack, it must be noted that: 1. The quality of the cement used must meet the standard regulations, and the mud content of bean stone, medium sand or coarse sand shall not exceed 3%; 2. Cement bean stone or cement mortar should be mixed evenly; 3. During construction, it is strictly forbidden to sprinkle dry cement when the surface layer is calendered; 4. It must be maintained according to regulations. 5. The base layer under the ground must be tamped according to the regulations; 6. The structural layer of the floor is prefabricated components, and shrinkage cracking may not be avoided due to the temperature difference.

Plain cement floor construction method:

First, remove the base chisel and debris, and water it to moisten, and brush 1 piece of cement slurry.

Spread out the cement bean stone or cement mortar, and level it with aluminum alloy fang.

After flattening, the pat is compacted and the surface layer is calendered.

Sprinkle sawdust on the dough for at least 7 days, watering at least once a day according to the situation.

Plain cement refers to a mixture made of cementing materials (organic, inorganic or organic-inorganic compounds), granular aggregates, water, chemical admixtures and mineral admixtures that need to be added in appropriate proportions, or composite materials with a stacking structure after hardening (usually cementitious materials, water, fine aggregates, and coarse aggregates.

1. Control the quality of sand and cement according to the routine, and the sand should be washed with water.

2. It is necessary to completely remove the masonry on the surface of the base layer, paint the ground ash and mud and sand, and chisel off the cement and concrete blocks on the protruding surface, level and flush the base layer.

3. When plastering the surface layer, the surface of the base layer should be fully moistened so as not to absorb the moisture of the mortar; And wipe off the stagnant water in the pit so that it is both damp and clean.

4. Control the mix ratio according to the routine and implement the operating procedures (such as the mortar must be stirred, and the state must be evenly eliminated, etc.).

5. Smooth the cement mortar before the initial setting, calender it before the final setting, and finally press out the bright light, which is appropriate to press 3 times. To master the time of Sun Yuan of calendering, the bridge is too early to press; It's too late to press and don't shine.

6. Strengthen maintenance. After the ground has hardened for a period of time, it should be cured with sprinkler water to avoid damaging the surface state, and the time to keep it moist is 10 days.

At present, there are several practices for industrial wind cement flooring.

No. 1: Ordinary cement mortar cleans the ground, dries thoroughly, and makes a pattern.

Grinding, brushing water-based.

Right polyurethane varnish protection, this kind of floor has low cost, long life, solid ordinary cement mortar floor.

No. 2: cement self-leveling ground, this kind of ground is very flat, uniform color, relatively high cost, no ordinary cement floor is strong and durable.

Cement self-leveling ground.

No. 3: Ordinary cement mortar finishes, after drying, do retro floor paint, ordinary retro floor paint generally has a life span of 3 to 5 years, which is enough for a rented storefront, but if it is your own house, you can consider using polyurea retro floor paint to do, with a life span of up to 20 years, and waterproof and wear-resistant.

Vintage floor paint.

It is possible to apply a bai retro floor du paint. The construction method is as follows:

1. Plain land treatment dao: the cement ground must be thoroughly dried, the ground must not contain oil stains, the ground can not be cleaned with water, and the grinding, repairing and dust removal work should be done according to the condition of the plain ground;

2. Mix the A component and B component of the retro floor paint according to the weight ratio of 2:1, use the electronic scale to batch, pay attention to the ingredients should not be too much, and the mixed material can be used for about 20 minutes at room temperature of 20 minutes, and the prepared solvent-resistant roller is rolled together, and the corners of the wall and other places that cannot be rolled are brushed with a brush;

4. The construction can be completed 24 hours before the person can be put on the person, and 72 hours after the heavy pressure. (25 shall prevail, and the opening hours of low temperature shall be moderately extended).

For the ground, when people are decorating, there are more methods, sometimes many people prefer to use cement floor, and this is also more economical, how to do cement floor is necessary to understand and know, in addition to the cement floor construction precautions are also to understand, so as to achieve good construction.

How to make a cement floor?

1. The process flow is copied from the elevation line, the base layer is treated, the installation is pre-embedded, the plastering cake and the standard bar are watered and wetted, the cement slurry is brushed, the cement mortar is paved, the wooden trowel is rubbed flat, the iron trowel is pressed three times, and the hair is cured.

2. Copy the elevation, and measure the elevation of the surface layer according to the horizontal control line on the wall, and bounce it on the wall.

3. The base treatment will clean up the debris, dust, soil, cement slurry and oil on the surface of the base and rinse it with water.

4. Installation and embedded inspection.

1) According to the height of the ash cake, the hot and cold pipes of the water supply should be pre-embedded, the pipe clamp should be fixed, and the water supply pipe should be pressed test;

2) The installation of drainage riser, sewage riser and floor drain is completed, and the hanging hole is completed.

3) The waterproof construction of the kitchen and bathroom is completed, the closed water test is completed, and the handover procedures are handled.

5. Watering and moistening the ground base layer is evenly watered, and the structural plate is fully moistened.

6. The plastering cake and the standard bar are determined according to the surface layer elevation level line that pops on the wall around the room, and the thickness of the surface layer plastering (should not be less than 20mm), and then the horizontal line is pulled to start the plastering cake (5 5cm), the horizontal and vertical spacing is 1 5 2 0m, and the upper plane of the ash cake is the elevation of the ground surface layer. If the room is larger, it is also necessary to wipe the bars. The ratio of mortar materials for plastering cakes and standard bars is the same as that for plastering mortar.

7. Before laying the cement mortar, a layer of cement slurry should be painted, and the area should not be too large.

8. After the cement mortar surface layer is coated with cement slurry, the 1:2 5 cement mortar is laid, and the mortar is evenly spread between the ash cakes.

9. After the wooden trowel is rubbed and scraped flat, immediately rub it with a wooden trowel, and check its flatness with a 2-meter ruler at any time.

10. After the iron trowel is pressed and the wooden trowel is smoothed, it is immediately pressed with an iron trowel until the pulp is released. After the initial setting of the surface layer mortar, press it a second time with an iron trowel to flatten the surface. The cement mortar is mechanically flattened before final setting, and then brushed in one direction.

Precautions for cement floor construction?

1. The cement floor can not be hollowed; The cement mortar surface can not be dusted and sanded, the mortar surface should be kept clean, and if there is ash and sand, it should be treated with cement sanding treatment agent;

2. The cement surface must be smooth, and the height difference within two meters is required to be less than 4mm; The ground must be dry, and the moisture content should be measured with a special test instrument not exceeding 17 degrees;

3. The strength of the base cement shall not be less than 10MPa;

After reading the above for you to introduce how to do cement floor, people do not have more understanding and understanding, in the production, must invite professional personnel, so that there will be a good effect, in addition to the cement floor construction precautions are also more important, more to understand, the effect will be better.

The dryness of the cement should be suitable; In order to ensure that the cement floor does not produce cracks and has better adhesion with the base layer, it is necessary to construct in sections. Water the wet base one day before construction. Special attention should be paid to the perimeter of the wall must be re-watered to prevent the surface of the concrete surface from drying and shrinking inconsistently, which is not only difficult to operate, but also affects the effect of the surface layer.

3) The brushing cement slurry should be professional and timely. Usually during construction, this process is ignored by the comrades, and the cement is sprinkled dry first, and then watered with a broom to sweep it, and some have water accumulation. And I used the following method at the flower and wood construction site:

Mix the plain cement slurry with a water-cement ratio of 1 with a bucket and sweep it in advance if there is water in the base layer. Brush the cement slurry and choose a person with a strong sense of responsibility to specialize in construction. The brushing time of the plain cement slurry is brushed according to the speed of paving, that is, the concrete is paved at any time, and the plain cement slurry is painted at any time.

4) Plastering cake According to the elevation line, make plaster cake on the ground, and the spacing should be one. When there is a floor drain or a slope requirement, the slope is done.

There are two ways to make a colored concrete floor in addition to painting. When pouring the cement floor, add toner to the concrete, and change the color of the ground through later dyeing.

Colored concrete is a waterproof, non-slip, anti-corrosion green floor decoration material. It is made by adding a layer of colored concrete (decorative concrete) to a dry concrete floor and then pressing it against the concrete floor using a special mold.

Concrete can make the cement floor permanently display a variety of colors, patterns, textures, realistically simulate natural materials and textures, and delineate the category patterns to your liking, and the longer the new one, the easier it is for people to realize that the building and the human environment, the natural environment is in harmony and harmony, and the integration is ideal.

One way is to add pigments to the cement, and the other is to post-dye.

Use white cement and add the pigment of your desired color.

Outdoor cement floor to do a good job of the foundation, the next is to lay a good level, according to the level of the standard pile, as for the inclined water, should be based on your cement floor use to determine whether to four-way or two-way, one-way drainage. The water discharged from the site should also consider whether it can be discharged farther away after flowing to the surrounding area, and whether it will form stagnant water. Because we don't know the purpose of your site and the surrounding environment, we can't give you specific advice.

As for finding the level, it is very simple, use a transparent water pipe that is longer than the field, filled with water, connect to the place where you want to hit the level, connect the two ends of the water pipe with a thin line where the water is level, and then lay a pile to fix the line is the horizontal line. If you have high requirements for the flatness of the field, drive more piles, pull more horizontal lines, and if the requirements are low, you can hit less. In principle, the horizontal lines and piles should be evenly distributed in the site.

After laying the horizontal line, according to the needs of drainage, the horizontal line of the place where it needs to be high can be appropriately raised.

First of all, the ground should be leveled, the ground should be tamped, or the ground should be compacted with a road roller, and then the cement mortar should be laid, and then the cement mortar should be leveled, and then the maintenance should be carried out.

Generally, the site is first grooved to the ash cushion ground.

Press it again with a chain rail car, then backfill the plain soil, put ash on it, and mix it with a mixer.

Press it again with a chain rail car, see how many times you have done the dust in the construction plan, and then pour the concrete.

The floor cushion should be 20 centimeters wider.

Other soft foundation treatment should be decided according to the actual situation on site, and the choice of replacement or drying.

You're talking about terrazzo floors, right? There are colored and plain colors. The method of mixing white stones into the cement mortar is the same as that of the cement floor, except that it is sanded with a sander or manual grinding wheel after the final setting.

It is divided into coarse grinding and fine grinding. Colored terrazzo floors need to be mixed with colors such as iron red.

This project requires high skills of plasterers, and the grinding time is also very strict, otherwise the ground will become a wolf.

It is better to use brand waterproof paint for bathroom decoration, because the bathroom, kitchen, floor, balcony, non-exposed roof and other non-long-term immersion, so it is best to be waterproof and moisture-proof. Coatings are well known, coatings are also called paints, which are coated on the surface of protected or decorated objects, and can form a continuous film with firm adhesion to the coated object. Its waterproof coating is formed by the volatilization of solvent or water or the chemical reaction of two components to form a thin film, so that the surface of the building is isolated from water, so that it plays the role of waterproof and sealing.

The waterproof film formed by the curing of the waterproof coating has crack resistance, impermeability, weather resistance, extensibility and elastic plasticity, which can play a role in waterproofing, seepage prevention and wall protection.

Red apple paint kindly reminds you.

Plain cement is difficult to plaster to survive. Generally, plain cement can be hung with cement putty on cement mortar.

It is recommended to do it at one time, and put iron mesh on the cement when there is still a batch. so that it will not crack. Finally, when it dries, apply the clear paint. Otherwise, the cement will have two colors.

Plain cement ash cannot be used as a wall finish.

Let me tell you.

First hang the net (iron mesh) on the surface, then plaster, cement sand 1:3 ratio.

After that, the plain ash is scraped and formed.
