What are the basic requirements for corundum wear resistant flooring?

1) Sprinkle water before concrete pouring to keep the foundation in a wet state. In order to reduce water leakage, the water-cement ratio and slump should be controlled, and the commercial concrete should be pumped by using a chute with manual discharge.

2) Concrete is poured to the elevation as soon as possible, and the local elevation is not reached by using concrete material to fill and vibrate, and it is strictly forbidden to use mortar to repair. Use a flat vibrator to vibrate, and use a special steel drum to roll repeatedly many times, columns, corners and other parts with a wooden trowel to pat the pulp. After the concrete is scraped, the cement slurry floats to the surface at least 3 mm thick.

3) After the concrete is poured, the rubber tube or vacuum equipment is used to remove the water, and the wear-resistant floor construction begins after repeating more than twice. Before the construction of the wear-resistant floor, the construction personnel should wear flat rubber shoes in the mid-term operation stage, and wear waterproof paper shoes in the later operation stage.

Specifically, you can log in to Fei Vas's ** to take a look, and it is very detailed.

Youyou Mathematics School Tips: A big reason for children's disobedience is the lack of parental relationship, you count, you spend on, **, work and how much energy the child has, if the proportion of children who care about children accounts for less than 20%, then please don't blame the child for not learning carelessly, disobedient, should reflect on it.

It depends on how well your concrete floor is done, good, when you make emery wear-resistant flooring, it is cheaper, because he is not very waste.

Contrarily...

1. Control the color and quality of corundum wear-resistant flooring

Ensure that the wear-resistant material and the cement concrete base have good adhesion and the color is consistent, mainly to control the spreading time of the wear-resistant material and the amount of spreading per square meter. The spreading time should be in the initial setting stage of the concrete. The amount of spreading per square meter should be spread twice to achieve an even spread.

2. Control the surface flatness of the corundum wear-resistant floor

The flatness of floor construction is mainly controlled by the flatness of the base layer of cement concrete. It has a very thin surface dense layer, so it is critical to control the flatness of the surface before the initial setting of the concrete. The flatness of the cement concrete is strictly controlled during pouring, and the front and rear scrapers can be leveled.

In addition, at the two construction joints adjacent to the concrete, because they are close to the construction joint formwork, the trowel is not easy to polish when the floor is collected and formed, so it is easy to cause a height difference at the construction joint.

Therefore, the construction joints should be cleaned after the formwork is removed. The method is to use a cutting machine to cut the concrete with a width of 50mm and a depth of about 50mm along the elastic line of the construction joint, and then chisel off before pouring the concrete for the second time, so as to ensure that the concrete of the second pouring is straight with the concrete that is poured, and pay attention to the elastic line and the cutting should be a straight line.

3. Prevent the wear of corundum wear-resistant flooring, such as shrinkage cracks

1. Control the drying of the concrete surface before spreading the wear-resistant material, such as the stagnant water on the concrete surface must be cleaned before spreading. Otherwise, the waterlogged part is prone to shrinkage cracks.

Cut the expansion joint in time. The cement concrete is cut 2 days after pouring, that is, 1-2 days after the completion of the wear-resistant floor. Otherwise, it won't work if it's too late.

To avoid the phenomenon of pulverization of corundum wear-resistant floor, the following construction precautions should be achieved.

1. Pour down the base concrete and tamp it, the concrete grade is not less than No. 25, and the site collapse degree is between 75 100 mm; 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 hardener is spread, and at the same time, a trowel and a disc are used to compact and trowel.

2. After about 1 2 hours, repeat the operation of spreading and compacting again; Only then polish and seal with a trowel and a blade, and at the same time repair the corners by hand; After that, spray the curing agent or cover the film to prevent cracking caused by the rapid volatilization of the upper moisture. From concrete leveling to covering curing, all operations are kept completed within 24 hours, and the construction can be opened for walking after 2 to 3 days.

Wear-resistant floor construction looks simple, but to do a lot of details to pay attention to, carelessly will collapse the quality of the whole project, from the first material spread to the subsequent surface polishing, surface curing agent maintenance, all require the accuracy of time. The construction team introduced that before construction, it is necessary to go to the site to observe and understand, pay attention to communication with the on-site construction personnel, etc., and try a small area before the construction to avoid large losses.

The NORMANG metal wear-resistant flooring used by our company is suitable for workshops, warehouses and industrial plants, supermarkets, heavy-duty machinery factories, machine shops, parking lots, cargo storage areas, logistics centers, schools, squares, and other pavements that bear heavy loads and require high wear resistance.

It is mixed with metal, cemented carbide aggregate and special cement and related additives, and laid on the surface of general concrete. This material has good toughness due to the high hardness of cemented carbide aggregate. In addition to high wear resistance, Norman corundum wear-resistant flooring also has good impact resistance.

The first step, the base surface concrete is mixed and filled; The strength of the newly poured concrete is more than C25, and the concrete surface should be compact, smooth, and free of water leakage.

The second step is to flatten and lift the pulp at the base level; Install the disc on the trowel and start leveling and extraction.

The third step is to spread emery for the first time; Spread 2 3 corundum materials evenly on the surface of concrete, about 5--6kg per square meter.

The fourth step is to knead and smooth; The edge of the wall can be manually kneaded and flattened with an iron trowel.

The fifth step and the second laying of emery; Spread 1 3 corundum materials evenly on the surface of the concrete.

The sixth step is to close the noodles; Adjust the inclination angle of the blade with the concrete setting time, speed and angle according to the hardening situation), criss-cross (more than 3 times) during the operation of the trowel. The corners are calendered in an orderly and co-directional manner with artificial steel trowels to avoid the appearance of wipes.

Step 7: In short, maintenance; Spray the special curing agent for the corundum floor within 4 hours after the construction is completed.

Emery, also known as silicon carbide, silicon carbide (SiC) is made of silicon carbide (SiC), which is smelted at high temperature by a resistance furnace with quartz sand, petroleum coke (or coal coke) and wood chips as raw materials. Silicon carbide is also found in nature with a rare mineral, moissanite.

Silicon carbide is also known as moissanite. Among the contemporary non-oxide high-tech refractory raw materials such as C, N and B, silicon carbide is the most widely used and economical. It can be called steel grit or refractory sand.

Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (salt needs to be added when producing green silicon carbide) and other raw materials in a resistance furnace by high temperature.

At present, China's industrial silicon carbide is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals, with a specific gravity of 2840 3320kg mm2 sand.

Mineral alloy aggregate (emery) ground hardener is composed of mineral alloy aggregate with a certain particle gradation, special cement, other admixtures and admixtures, which can be used immediately after opening the bag. It is evenly spread on the concrete surface that is about to be set in the initial setting stage, and is processed by special means, so that it forms a whole with the concrete floor, and has high compactness and coloring of the high-performance wear-resistant ground.

Scope of application is used on concrete floors that must be wear-resistant, impact-resistant and dust-reduced, such as: warehouses, docks, factories, parking lots, maintenance workshops, garages, warehouse-style shopping malls, docks and places where uniform colors are required to improve the working hygiene and aesthetics without corrosive media. Features enhance the wear resistance and impact resistance of concrete floors.

It greatly improves the density of concrete, reduces dust, increases the oil resistance of the ground, and forms a high-density, easy-to-clean, and impermeable ground. Constructed together with the concrete floor, the construction period is short. It is durable, reducing the cost of periodic painting or thickening of the surface.

It has less dust than non-metallic hardened ground, the appearance is as shining as a starry night, the impact resistance is better, and it has a certain effect on anti-static.

The strength of the base concrete is required to reach more than C25, the water-cement ratio is controlled below, the concrete slump should be controlled at 70-100mm, and the concrete mixture of the concrete is minimized and the water leakage is controlled. 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. The base concrete should be poured and compacted according to the standard of excellent concrete, paying attention to accurate dimensions and reducing the generation of slurry.

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 screeding layer, it is recommended that the screed concrete should be made of fine stone concrete, with a thickness of not less than 50mm, and consider the configuration of telescopic reinforcement mesh. Special attention should be paid to the corners of the base concrete construction block to ensure that the concrete vibrates and compacts, and additional strengthening treatment should be taken.

It is suitable for the construction of newly poured concrete, and is suitable for indoor and outdoor concrete surfaces 1, industrial plants, production workshops 2, warehouses, logistics centers 3, garages, parking lots 4, supermarkets, and stores.
