What is concrete surface hardening powder?
Concrete hardening powder, also known as anti-wear concrete powder; It is a product that is used to create a smooth surface, smooth concrete surfaces and polish it.
The purpose of using this material is to increase the high mechanical strength of concrete to withstand abrasion, impact and other damage. Concrete anti-wear powder is made by spraying dry powder on fresh concrete, which in the end creates a resistant anti-wear surface for them.
This versatile system strengthens the cohesion of the surface on the concrete in an integrated manner, which is used in many places, such as industrial places that are exposed to heavy traffic. In this article, we intend to introduce this product, review the types of hardening powder and its properties.
Concrete hardening properties
In the manufacture of concrete hardeners, a substance called microsilica gel is used, which is offered in different packages in the market. This extraordinary material has caused many different properties and advantages in concrete.
First of all, it should be said that micro silica gel greatly increases the hardening strength of concrete and consequently increases the tensile strength of concrete. As you know, concrete naturally has low tensile strength and to solve this problem, rebar or the same reinforced steel is used in it.
Concrete hardening powder has very low permeability. Simply put, this product is sealed and this feature makes it. The concrete in question is anti-wear and is very resistant to external chemical attacks such as chlorine ion attacks and does not allow concrete to be damaged.
Another advantage of this material in concrete is that in concreting that is done in bulk, the hydration temperature is significantly reduced. This product is produced and sold in powder form and does not contain chlorine ions. In most cases, the type of concrete hardener packaging is in the form of a bag.
Advantages of concrete hardening powder
Concrete hardening powder, which is one of the most important building materials, has many advantages that we intend to explore in this section.
1. Concrete hardening powder is very resistant to dynamic and static shocks.
2. This widely used powder is very resistant to natural factors such as sunlight, wind, rain and other natural factors.
3. Concrete hardening powder is very light and has high strength.
4. This powder is very suitable for substructures because its adhesive strength is very high.
5. Also, due to the many advantages of this product, it is very suitable for infrastructure and floor construction operations, which include traffic and transportation of heavy vehicles.
6. Concrete hardening powder is produced and sold in different shapes and in different colors such as gray, red, blue.
7. Abrasion resistance of this product is very high and is more than 160% of bed concrete.
How to use concrete hardening powder
Concrete hardening powder, like other products, has its own method of application and how to use it, which can be used well if you pay attention to them. In this section, we are going to examine how to use special powder for anti-wear concrete.
Depending on the use of the desired surface, the concrete hardening powder is sprayed on concrete sections to absorb all the moisture in the concrete well.
If you want the concrete surface to be smooth and even and its strength is high; you will need to complete the final level using an electric property, otherwise known as a power trowel. Once the spraying is complete, start spraying the cured concrete or curing water.
Application of concrete hardening powder
Concrete hardening powder is used in many concrete structures that have different types, including reinforced and unreinforced. By using this product in structures, their useful life is greatly increased.
Note that the largest and most common use of concrete anti-wear powder is in places where the concrete is exposed. This is because concrete in such structures is more prone to environmental damage, including physical and chemical damage.
Therefore, concrete hardening powder is used in many structures such as sealing tanks, concrete sources, tunnels and water transfer canals.
Also, in cases where the spaces in question are places where concrete is dealing with water and the possibility of concrete wear and damage is very high, this powder must be used.
Also, in structures such as bridge decks and parking lots that are exposed to a lot of wear, concrete hardening powder must be used.
The following are the places where concrete hardening powder needs to be used:
1. Flooring of halls and yards of industrial factories
2. Parking and location of machines
3. Car loading and refueling platforms
4. Industrial cold storage, repair shop and car wash
5. At the installation site of turbines and generators as well as power plants
6. Plane hangar and helicopter take-off and landing area
Properties and effects of concrete hardening powder
This widely used powder has many properties and benefits that we want to examine in this section.
1. Using concrete hardening powder, the final surface is integrated and is resistant to any abrasion, impact and erosion.
2. Concrete hardener powder is very easy to apply and can be applied very quickly.
3. Execution of internal and external surfaces of the structure can also be used.
4. The adhesion and cohesion of concrete hardening powder is very high.
5. Also, concrete hardener is very resistant to melting and freezing cycles.
