How to make emery flooring? The practice of emery flooring

When the initial setting of the base concrete (about 3 4h), you can carry out the construction of the wear-resistant floor, first install the disc on the trowel, polish the concrete as a whole and gradually retract it from the periphery, play the role of leveling and slurry, and the initial setting time of the concrete should be determined according to the operating environment, climate and other environments. Generally, the foot sags no more than 5mm, and the pulp is lifted and laid with corundum wear-resistant materials.

Kneading and smoothing: use a trowel with a disc to grind and disperse, so that it is combined with the base concrete slurry, and be careful not to rub it too much. The edge of the wall can be manually kneaded and flattened with an iron trowel.

After the construction is completed and cured for 7 days, the sawing and lattice seam is carried out according to the column distance (6m in length and width), and the saw joint must be elastic, with a width of 5mm and a depth of 20mm.

The construction steps of emery floor are as follows:

1. The treatment of the construction surface needs to ensure the smoothness of the construction surface and the existence of no stains and dust.

2. Sprinkle emery on the construction surface, and knead and smooth the work.

3. Then carry out the second laying of emery, and then do a good job of finishing, curing and cutting in order to ensure the overall quality.

The following points should be paid attention to in the construction of emery:

1. In the process of emery construction, it is necessary to pay attention to the quality of the selected materials, which should not be too bad, otherwise it will affect the quality of the emery surface layer, and the use effect will be greatly reduced.

2. Since there are many links that need to be paid attention to in the construction of corundum, try to find an experienced and big-brand construction team, and its construction technology will be better.

3. Nowadays, there are many kinds of colors of emery materials, and the decorative effects are different, and there will be differences, but the strength brought is about the same. Therefore, when buying materials, it is not only necessary to see whether the emery matches the interior style, but also to ensure that the budget will not be overrun, otherwise it will be very troublesome and affect the use.

In fact, the emery hardened floor is treated and reinforced on the basis of the emery floor, which further improves the performance of the floor, increases the hardness of the floor a lot, and enhances the impermeability ability. The specific methods are as follows: cushion treatment, steel bar bundling, base concrete pouring, scraping (while corundum mixing) Smoothing surface slurry The first time spreading emery mixture and trowel and polishing, the second sprinkling of emery mixture and trowel, polishing Surface modification and maintenance Emery hardened floor.

Wuhan Qifeng and Xi'an Deligu floors are very good.

When the leveling layer is not dry, the aggregate is evenly spread on the leveling layer; The corners are reinforced, and the ground is smoothed; Sawing concrete at the appropriate location, making expansion joints, and filling with the required caulk; Roller coating, trowel trowel, trowel, polishing, finishing, curing.

1. The strength of the base concrete is required to reach C25 or above, the water-cement ratio is controlled below, the concrete slump difference should be controlled at 70-100mm, and the concrete mixture should be segregated to minimize and control the water secretion.

2. In order to ensure that the concrete mixture has sufficient fluidity and is conducive to construction, it is recommended to add appropriate admixtures to the concrete.

3. The base concrete should be poured and compacted with reference to the standard of excellent concrete, paying attention to accurate size and reducing the generation of floating slurry.

4. The surface of the hardener should be constructed at the same time as the concrete structure layer, if it is necessary to construct at the same time as the leveling layer, it is recommended that the concrete of the leveling layer should be made of fine stone concrete, with a thickness of not less than 50mm, and consider the configuration of telescopic reinforcement mesh.

5. Pay special attention to the corners of the base concrete construction block to ensure that the concrete is vibrated and compact, and additional strengthening treatment should be taken.

Construction method of emery wear-resistant floor:Step 1: When the leveling layer is not dry, the aggregate is evenly spread on the leveling layer The second step: the corners are reinforced and the ground is smoothed.

Step 3: Cut the concrete in the appropriate position, make expansion joints, and fill up the required caulking material Step 4: Roll coat with transparent sealant, trowel, trowel, polish, and cure. Step 5: Trowel, finish, cure.

1. 2 3 of the total amount of the first spreading, compacting and rubbing 2 with a polishing disc, 1 3 of the total amount of the second spreading, compacting and rubbing 3 with a trowel disc, after the initial setting, wipe it with a calender.

4. Check the flatness after sprinkling and wiping, adjust the material in time for low-lying places, and then compact and rub the hair and wipe the place.

5. Before completion, polish with a trowel to achieve the completion of the process 6. Varnish with curing agents such as ground wax according to requirements.

Emery wear-resistant floor construction technology:

The wear-resistant material is a ground hardener material, which is composed of non-metallic mineral aggregates, metallic mineral aggregates and special additives.

Wear-resistant flooring has the advantages of high surface hardness, high density, wear-resistant, dust-free, not easy to peel off, economical, applicable, and wide range.

The integral wear-resistant floor abandons the traditional practice of separating the concrete base and the surface layer, thereby eliminating the cracks caused by the poor combination of the base and the surface layer.

It simplifies the process, shortens the construction period, saves labor costs, and is more and more widely used in factories, warehouses, runways, docks and other projects.

First, the material of wear-resistant flooring

Emery hardener material is divided into two components: aggregate and cement. The aggregate is sandy, with an average particle size, accounting for about 60% of the total; The cement is treated high-grade cement, in addition to the natural color of cement, there are red, yellow, green, gray and other colors to choose from.

The composition of corundum hardener aggregate is natural ore. It is a non-metallic aggregate that does not rust, and the hardness is above 7 degrees on the Mohs scale. In addition to natural ore aggregates, the weight of other cement, pigments, etc. shall not exceed 25% of the total weight. The amount of wear-resistant materials is determined according to the material specification and design requirements.

2. Wear-resistant floor construction equipment

In addition to the use of conventional tools for smashing and plastering the concrete floor, prepare the following tools.

1) Water drainage tools: rubber tubes or vacuum suction equipment.

2) Leveling slurry tool: 150 steel pipe with sand filling in the middle, the length is greater than the width of the ground mold by more than 500mm, and the two ends are equipped with rotatable pull rings.

3) Piercing machine: produced in Canada, the chassis is a four-bladed steel sheet, which can be calendered by adjusting the angle of the steel sheet (the angle is small when it is used for the soft surface layer, and the angle is large when it is used for the hard surface layer).

4) Flat-soled rubber shoes: used after the initial setting of concrete; waterproof paper shoes or waterproof paper bags; The surface layer of the blade is calendered.

3. Wear-resistant floor construction organization

Based on 500 square meters of days, in addition to pouring down the ground concrete conventional personnel, the following construction personnel are also required: 3 concrete leveling personnel, 2 wear-resistant material transportation, 3 wear-resistant material spreading, 3 polishing machine construction, and 3 trowel leveling. According to the above standards, continuous and uninterrupted construction, 6 7 trowels and equipped with corresponding personnel, can complete 2000 square meters of days.

Fourth, wear-resistant floor construction preparation

1) The sand and gravel cushion under the floor is compacted with a road roller.

2) Set the template (steel template or channel steel) according to the design elevation, detect the elevation of the template at any time with a level, and adjust the deviation with a wedge block.

3) According to the requirements of the specification, divide the warehouse and lattice seams according to the vertical and horizontal axis.

4) The maximum particle size of the crushed stone used in concrete is 30mm, and the water-cement ratio and slump should be as small as possible.

5) The concrete grade is not less than No. 25, and the site collapse is between 75-100 mm.

The practice of emery flooring

1.To treat the cushion, the cushion treatment is to carry out the flat treatment of the place, in the construction process to copy the flat, pay-off, do a good job of elevation control, after the flat treatment of the place is completed, according to the drawing planning request for steel binding.

2.Its base concrete pouring concrete pouring before pouring to make the foundation in a wet state, concrete as far as possible once poured to the elevation, part of the high place with concrete material to make up and vibrate, it is strictly forbidden to use mortar repair. When vibrating, use a flat vibrator to vibrate, and the column, edge, corner and other parts are slurred with a wooden trowel, and the cement slurry floats out after the concrete is scraped and the surface is less than 3mm thick.

3.The opportunity for the first sprinkling of emery mixture and smoothing and polishing of corundum mixture varies with climate, temperature, concrete cooperation ratio and other factors. Spreading too early will cause the emery to sink into the concrete and lose its effect; If the concrete has solidified too late, it will lose its cohesion, so that the emery mixture cannot be bonded with the concrete and peel off.

4.When spreading the emery mixture for the second time and smoothing and polishing the second spreading, measure the levelness with a ruler or a straight scraper first, and adjust the unevenness of the top spreading, and the second direction should be straight for the first time. The second spreading amount is 1 3 of the full amount, and immediately after spreading, smoothing, grinding, and repeating the work of the grinder less twice, the grinder should be intertwined vertically and horizontally when working, uniform and orderly, to prevent data collection.

Regarding the practice of emery flooring, the recommendations are as follows;

The first step: when the leveling layer is not dry, the aggregate is evenly spread on the leveling layer;

Step 2: Reinforcement of corners and smoothing of the ground;

Step 3: Sawing the concrete at the appropriate position, making expansion joints, and filling the required caulk;

Step 4: Roll coat with transparent sealant, trowel trowel, trowel, polish, finish, cure.

Step 5: Polish, receive, maintain.

First of all, the base concrete is poured and compacted, and the concrete strength is not less than C25, and the concrete must contain 350 m?cement grade above; The water-cement ratio must be fine stone concrete and its thick bottom must not be less than 50mm, and the on-site drop is between 75-100mm;

Then use a special trowel and a disc to further level the concrete to ensure that the concrete surface is smooth and compact. At the beginning of the concrete setting, the emery aggregate is sprinkled, and at the same time, a trowel and disc are used to compact and trowel.

After about 1-2 hours, repeat the work of spreading compaction; Polishing with a trowel and repairing the corners by hand; Finally, spray curing agent or cover curing, and all process protection is completed within 24 hours.

After the construction is completed, it can be put on the walk for 2-3 days. In the appropriate position (generally 6m*6m as a unit), sawed by the construction sawing machine to the concrete thickness of 1 3, the shrinkage is filled with the required caulk.

When creating flooring, you need to understand the specific process and method. What about corundum flooring? pchouse will take everyone together to solve the difference.

1. The concrete base of the sand floor excavated by the King Kong Bridge is poured and leveled, and the ground to be constructed is cleaned first, without garbage and loose particles, and at the same time, water should be sprinkled in advance to make the construction ground wet, and then the water-cement ratio needs to be controlled. The pouring thickness should be poured to the required height at one time, so that the ground is uniform and dense. In this way, the density of the ground floor is higher, and the addition of concrete can make the emery more permeable resistance.

Pay attention to the selection of concrete sand, and use as few additives as possible.

2. When the whole layer of the ground floor leveling layer has not dried, evenly sprinkle the aggregate on the leveling layer.

3. Strengthen the corners of the emery ground and smooth the ground; For walls, columns, doors and formwork and other edges where water loss is fast, priority should be given to spreading construction to prevent the sensitization effect from being reduced due to water loss. Carry out mechanical trowel with cement trowel machine, so that the natural corundum aggregate is combined with the concrete base slurry, and the corners and other parts can not be smoothed mechanically, and the manual trowel is adopted, and it is not appropriate to wipe excessively.

4. Carry out the second sprinkling and wiping of the ground, and measure the levelness with a ruler when sprinkling the material for the second time, and adjust the unevenness of the first spreading. The amount of sprinkling material in the second pass is about 2 5 of the total amount of material per unit area, and the parts that lose water quickly speed up the spreading. Smooth it out in the same way.

The operation of the glazing machine should be staggered vertically and horizontally, evenly and orderly, to prevent the accumulation of materials, and the corners should be treated with wooden trowels.

The practice of emery floor is very simple, only when the base concrete is dry 5-6 years before the initial setting. Spread the aggregate, strive to spread evenly, scatter the material in two times, and ensure the amount.

After finishing, it is similar to the cement that is polished, but the hardness is higher than that of ordinary cement, so the surface is impermeable, and sewage will seep into it. Secondly, it is often not teased and cured by the trailer will also be powdered, in fact, it is best to add a layer of concrete sealing curing agent on the surface, which not only has high hardness, dustproof, but also sealed, easy to do hygiene.

There are many advantages such as no shell, and the only disadvantage is that only the mountains and fields are transparent. However, there are also colored ones on the market, one is to increase the cost, the second is that the construction is much more complicated, and the third is that the color will be uneven if the dyeing is not good.

Advantages of emery flooring

1. Strong wear resistance and advantages.

Emery floor not only has quite good wear resistance, does not need to invest too much labor cost and time cost, can greatly reduce the quality of the floor, to ensure a high cost performance.

2. High aesthetics and easy maintenance.

Compared with traditional flooring, corundum flooring has a richer variety of colors, and maintenance is also very simple and convenient.

3. Long service life.

Due to the wear-resistant and compression-resistant properties of emery, there will be no problems with long-term use. As long as it is regularly maintained and cleaned, it can be used to extend its service life.

4. Quickly put into use.

Emery flooring can be applied at the same time as concrete, can be completed quickly and put into normal use, and it is also a great alternative to traditional ridged terrazzo flooring.
