What are the consequences of sand on the concrete floor?

General production types of enterprises, is now a lot of their own production workshop, the workshop floor is the place of use frequency is very high, with the hauling and other machinery and equipment, goods are, believes that many enterprises have met the ground on the matter of sand, we also very distressed, sand ground up, after all, look not beautiful, not only after also can appear some problems when using, cleaning and maintenance is more difficult to do in the late.

But in the face of such problems, some enterprises in order to save construction costs, will not be too concerned about, they will want to, not is ground up the sand, can have what too big impact, often have to do is clean, need not to go, but relatively some enterprise attaches great importance to this phenomenon, to all sorts of ways to solve!Compared with the two, in fact, the latter is more responsible for the performance of the enterprise. The emergence of sand on the ground will bring a serious impact on the enterprise, such as:

1. As the equipment used in the current factory is some high-tech equipment, if the dust on the ground is easy to enter the equipment, in the long run, it will increase the maintenance rate of the equipment and reduce its life.

2. For some enterprises engaged in the production of electronic components, it is easy for dust to adsorb on the electronic components due to sand rising on the ground, which will reduce the quality of products and increase the number of unqualified products, which will affect the image and benefits of enterprises.

3. As a production-oriented enterprise, when customers visit the workshop, the floor is covered with sand, which makes the workshop full of dust. Moreover, the floor is uneven, which will naturally reduce customers' evaluation of us and directly affect the business volume of the company.

4. If the floor is defective with sand, the enterprise cannot pass the relevant certification, especially in some industries such as food, health, clothing, accurate electronic instruments, etc.

5, we used to use the floor products in the majority of ordinary concrete, this floor products often in the use of three or two years, because often by some wear resistance and impact, general cloth in the phenomenon of sand, and the longer the service life, this phenomenon will be more serious, and even affect the normal use.

Late June, terrazzo floor and floor tile ground, although compared with concrete floor products effectively solved the problem of the floor up the sand, but the surface itself and the concrete base is stripping, in under the action of gravity, it is easy to cause the ground surface shell, empty drum, fracture, fall off phenomenon, not only influence the surface level off, clean, and with the use, damaged area will be more and more big, shorten the service life, and affect the normal use.

Thus floor up sand problems will impact on our business in the normal operation of serious, so here recommend if problems of sand on the ground, must solve, cannot be ignored because of cost savings, the consequence will bring serious impact to the production of enterprises, then perhaps there will be more economic loss, so that thed loss outweights the gain!

So, how to solve the problem of sand and dust on the ground?The floor engineer suggests that after the concrete is finished, the ground should be hardened with concrete sealing curing agent, which can not only completely solve the problem of dust and sand rising on the ground, but also make the floor hardness rise to Mohs hardness level 8, and the floor still has the luster like marble.Easy to clean and maintain, improve the corporate image, avoid the above problems caused by sand on the ground.

Explanations of relevant articles in this article

floor

The ground floor is the part that the ground floor room and soil layer contact, it bears the load of the ground floor room, the requirement has certain strength and rigidity, and has moistureproof, waterproof, warm, wear-resisting performance.There is a close relationship between the stratum and the outdoor site of the building. It is necessary to deal with the relationship between the ground and the platform, the steps and the site along the edge of the building, so as to make the handover between the building and the site clear and harmonious as a whole.The floor is suitable for some places with high hygienic requirements, such as hospital floor, food factory floor, pharmaceutical factory floor, laboratory building floor and machine room floor.And requirements of stamping, corrosion and wear resistant ground such as underground parking, factory warehouse (forklift), etc.Building industry: Floor is the part of the building bottom room and the lower soil layer contact, it bears the ground load of the lower room, should have good wear-resisting, moisture-proof, waterproof, heat preservation performance.

The sand

Sand means: the surface of the concrete base is weak in the external force, the weak part falls off the base, resulting in the loss of the concrete fine aggregate composed of sand, so that the surface layer loses luster, if not treated for a long time, there will be a large area of surface layer defects, and serious exposed material phenomenon.The main reason for sand formation is that the water-cement ratio is too large: that is, the amount of mixed concrete is large, which leads to the concrete surface bleeding and reduces the surface strength of concrete.Unreasonable grading of sand and gravel, high silt content: unreasonable grading of aggregate and too fine soil and sand also easily lead to sand on the ground, affecting the early hydration of cement and the setting of concrete.Excessive vibration in the construction process: exacerbates the bleeding of concrete surface, resulting in low strength of concrete surface.Improper maintenance: failure to timely maintain or insufficient maintenance, exposure to the sun or wind causes a large amount of water loss on the concrete surface, the surface cannot be fully hydrated, resulting in low strength.Other reasons: the compaction time grasp is not good, the concrete surface does not reach a certain strength on the human operation, the construction of concrete surface under low temperature is frozen, etc.Interface agent mixing cement is often used on the site for coating and scraping, hoping to cover the sand, in fact, this will not achieve the desired effect, generally dry surface will crack, flake, large area of the shell.This is because the grass root is not handled well. It is a completely wrong idea that the grass root is powdered and the effect of repair can be achieved through coverage.Sand lifting treatment: concrete floor hardening agent can be used to treat sand lifting ground. For example, A5 concrete hardening agent produced by Beijing Polymerization reinforcement Building Repair Technology Center is specially developed for concrete sand lifting. After fully absorbing hardening agent, concrete can root out sand problems, and at the same time make the original concrete improve a label.

The ground

The ground (floor) is usually composed of the surface and the base (Figure 1).The ground
