The scope of application of concrete surface enhancers for concrete surface enhancers

Concrete. Surface enhancers are also known as liquid floors.

Hardeners, concrete sealing curing agents. As a water-soluble liquid chemical hardener, the exterior of the concrete surface enhancer is colorless and transparent. Our common concrete surface enhancers have two-component materials and one-component materials, and in comparison, the reinforcement effect of two-component concrete surface enhancers is better.

Alkali metal silicate is the main component of concrete surface enhancer, today I will introduce you to some knowledge of concrete surface enhancer.

The first is the scope of application of concrete surface enhancers:

The first is the application of terrazzo floors, which, if polished with a machine, can be made to resemble marble.

The effect of the ground. In order to allow the concrete surface enhancer to better penetrate into the interior of the concrete, the surface of the concrete must be required to undergo many days of wet curing, and it can only be constructed after it is completely dry. In addition, concrete surface enhancers can also be applied in cement-containing applications.

composition of concrete products, you can make it surface enhanced. When the strength of cement mud or concrete floor is not enough, concrete surface enhancer can be used to harden it.

The second is what is the role of concrete surface enhancers?

Because the concrete surface enhancer has a very low surface tension, it can quickly penetrate into the interior of the concrete, and some by-products in the concrete for a second reaction, resulting in a large amount of silica gel, and these gels can block the pores inside the concrete, using this principle can increase the compactness of the concrete surface. In general, concrete surface enhancers can increase the strength of concrete by between 15% and 30%. Among them, the chemical reaction of two-component concrete surface enhancer in concrete is more complex, and it will also produce some harder substances, which makes the hardness of concrete increase more obvious to a certain extent.

Therefore, the main function of concrete surface enhancer is to enhance the compactness of the concrete surface.

Thirdly, what are the construction methods of concrete surface enhancer?

In general, the construction method of concrete surface enhancer is to spray with low-pressure nozzles, and a small amount to use roller coating. If you cooperate with the grinding and polishing machine during the construction process, the brightness of the concrete surface can be better.

The above is to introduce to you some knowledge of concrete surface enhancer, in addition, when using the concrete surface enhancer, it must be evenly sprayed on the ground, so as to play its real role.

Concrete surface enhancers must be applied to the surface of cement mortar or concrete that has already been formed

1. In order to ensure that the concrete surface enhancer can penetrate more into the concrete, it is recommended that the new cement mortar or concrete surface (preferably with machine light) be wet cured for at least 7 days and completely dried before construction. Of course, some concrete surface enhancers are applied 24 hours after the completion of the new construction ground in order to save material and construction time.

2. The strength of cement mortar or concrete ground surface layer caused by various reasons, ash and sand, concrete surface enhancer can be used for hardening and dust-proof treatment: the surface hardness and wear resistance of the treated ground are significantly increased, and there is no ash and sand, but this treatment method does not change the appearance of the original ground, therefore, it will not repair the damage of the original ground. If you want to repair the damage to the original ground (such as potholes, cracks, etc.), you must repair or polish it as a whole.

3. Surface sealing and enhancement of terrazzo floor or corundum wear-resistant floor: if it is polished and polished with the machine, these two kinds of ground can make an effect similar to that of marble floor.

4. Surface enhancement of concrete products or concrete components containing cement components: For the surface enhancement of concrete components, it should be noted that the better the original strength of concrete components, the smaller the range of concrete surface enhancer can be improved, and for concrete above C30, the strength improvement ability of concrete surface enhancer is already very small.

1) The concrete surface enhancer penetrates into the inside of the concrete, chemically reacts with the chemicals in it, shrinks the pores and cracks of the concrete, and makes the concrete dense, thereby improving its hardness. The product needle is composed of inorganics, chemically active substances and complexes.

2) The product is widely used in: the concrete that has been poured and formed on the foundation building with insufficient strength.

Each product has its reason for existence, how much strength can be improved, it depends on how strong the concrete you design, and then what strength you want to achieve, for example, if the strength of the concrete you designed at that time is C30, but you want to achieve the strength of C40 by painting the reinforcing agent, our reinforcing agent manufacturer can clearly tell you that this is impossible to achieve. For example, if the concrete strength you design is C30, and the rebound strength you measure is only about 25-30 or even lower due to various reasons such as insufficient maintenance, then I can responsibly assure you that as long as the reinforcement is applied according to the requirements, there is no problem with the strength of 33-35 in the later stage.

Concrete surface enhancer is a chemical product that improves the surface strength of concrete, which is a water-based material, colorless and odorless, spraying concrete surface enhancer on the concrete base surface, and the rebound strength is increased by 5-10MPa after a week. At present, the effect of [Guheng concrete surface enhancer] is relatively good.

Just brush a layer of reinforcing agent on the surface to enhance the surface hardness, and the rebound value will naturally increase.

After hardening, it can improve the compactness, enhance the impermeability, and improve the life of concrete.

Before understanding concrete surface enhancers, it is necessary to figure out what factors are not strong enough for concrete:(The company's official website:

1. Poor quality of raw materials:

1) Poor cement quality: 1. The actual activity of cement is low; 2. The stability of cement is unqualified;

2) Poor quality of aggregates (sand, stone).(The company's official website:

1. The strength of the stone is low;

2. Poor volume stability of stones;

3. Poor shape and surface condition of the stone;

4. The content of organic impurities in sand and stone is high, the content of dust is high, and the content of mica in sand is high;

3) The quality of the mixed water is unqualified

4) The quality of the admixture is unqualified or the composition ratio is improper.

2. Improper concrete mix ratio: (company official website:

The concrete mix ratio is one of the important factors that determine the strength, in which the size of the water-cement ratio directly affects the strength of concrete, and other such as water consumption, sand rate, ash ratio, etc. also affect the various properties of concrete, resulting in insufficient strength accidents.

1) Increased water consumption: the more common ones are that the water addition device on the mixer is not metered accurately; The water content in sand and stone is not deducted; Even adding water at the watering site, etc.

2) Apply the mix ratio at will;

3) The dosage of admixtures is not accurate.

4) improper use of admixtures;

5) The measurement of sand and gravel is inaccurate and the amount of cement is insufficient.

3. The construction process is incorrect (the company's official website:

(1) Poor stirring, too short or too long to cause unevenness.

(2) Serious leakage of cement slurry during pouring; Concrete false setting, initial setting; The vibration is not real.

(iii) Improper maintenance; Such as early lack of water and dryness, freezing, etc.

Moving on to concrete reinforcing agent, it is an additive that can improve the surface strength of concrete. It is colorless, transparent, organic or inorganic liquid material, easy to use, non-combustible, highly penetrating, sealable concrete, and meets all VOC rules and USDA ratings. The product is composed of inorganics, chemically active substances and complexes, which by penetrating into the interior of the concrete, chemically react with the chemicals in it to form a gel, shrink the pores and cracks of the concrete, and make the concrete a dense whole, thereby improving its surface hardness.

The specific color of the liquid is not easy to say, it is different from one to another, and it can be sprayed directly on the surface of the structure with a sprayer, or brushed on it.

The product is harmful to the human body, try not to touch it when operating**.

Product principle: To put it bluntly, it is to speed up the carbonization rate and increase the surface compactness, in fact, there is no improvement effect on the internal structure, and it is used to improve the rebound strength and cope with the acceptance of the owner or the quality supervision station.

Applicable occasions: After the concrete age is reached, or even the overage period is long, but the strength is not enough, you can use this thing. But don't expect to grow you a lot, we're growing to . .

I'm a user, I've used it 2 times, and it's expensive.

Concrete surface enhancer is a water-soluble liquid chemical hardener.

The appearance of concrete surface enhancer is colorless and transparent, and there are common one-component materials and two-component materials on the market, and the reinforcement effect of two-component materials is relatively better. The main components of concrete surface enhancers are reactive alkali metal silicates or modified alkali metal silicates, catalysts, additives, etc.

Concrete surface enhancer has a very low surface tension, can quickly penetrate into the concrete, react twice with cement hydration by-products such as calcium hydroxide, and produce a large amount of silica gel by burning and grinding, thereby preventing the capillary micropores inside the concrete, thereby increasing the density of concrete, and the compressive strength, hardness and wear resistance of the concrete surface can generally be improved. 15-30% of the strength of concrete.

Some two-component concrete surface enhancers are more complex than the chemical components in concrete. In addition to silicone, some hard and dense materials are also produced, which make the strength of the section stuffy concrete more obvious. Two-component cement floor sand treatment agent belongs to this material, which can harden cement concrete floors and lime sand with poor surface strength.

No sand or ash is produced.
