Strengthening of concrete by ironing

It is often possible to meet the fact that over time, the monolithic structures that are being exploited begin to crack and collapse. This is due to the fact that in the process of pouring or mixing the solution errors were made or with the influence of the environment.

All this leads to the fact that a caring owner at a certain moment has a completely natural question: how to make concrete stronger? Professionals recommend for the implementation of this goal to use the method of iron concrete surface.

Surface ironing technology

Using this method is simply necessary in order to endow the surface with those qualities that will contribute to the extension of the service life of the monolith. Iron allows us to endow worn concrete with durability and resistance to wear and moisture.

To implement this method, various means are used:

• Mixtures;
• Impregnation;
• Cement.

The composition of these funds may include components such as:

• Quartz;
• Granite;
• corundum;
• Liquid glass.

Ironnation is a fairly simple and reliable way to strengthen the surface and every owner can implement it with his own hands.

Options for implementing the method in practice

Strengthening the structure can be implemented in two known ways;

1. Dry. This method is applicable for horizontal surfaces and is implemented by backfilling with a dry cement powder of a concrete base. The coating obtained in this way will differ in surprising smoothness, hardness and ability to repel water. Dry iron is the procedure most commonly used to strengthen a floor covering;
2. Wet. This method is implemented by applying to the surface of a wet cement solution, which may contain various additives. This method is considered universal and is used to strengthen surfaces, both horizontal and vertical.

Note! Most often, such additives are sand in relation to cement 1 to 1. In addition to sand, these components are liquid glass, aluminate, and other means designed to increase moisture resistance and coating strength.

The cost of the production of work both dry and wet method is almost the same, so the choice of one of the ways to strengthen the surface will depend only on the directionality of the treated surface and your personal preferences.

Types of mixtures for hardening

Zheleznenie can be implemented using a variety of tools that can be easily purchased at any hardware store.

Polyurethane impregnation

The fixer of polyurethane type concrete in the process of applying penetrates into each pore on the surface, filling it, and thereby creating a durable bilge coating.

The advantages of this impregnation include:

• Ability to work at temperatures up to -25 degrees;
• Creating a coating that can repel moisture;
• Creating a coating that is protected from ultraviolet rays;
• A wide range of colors;
• Low cost.

Liquid glass

This substance is added to the cement mortar in order to impart moisture resistance to the surface and reduce dustiness. The price of realization of the ironing method using liquid glass can be quite high.

Portland Cement Blends

Reinforcement of concrete of this type is used in cases where the surface must be given strength.

The composition of this solution may include:

• Modified additives;
• Quartz sand;
• Basalt;
• Polymer fibers, etc.

Each such component performs its own role. So, for example, in order to ensure the composition penetration into the top layer of the coating and reliable adhesion with it, as well as for the purpose of additional reinforcement, polymer fibers are added to the composition.

Ironnage at home

The following instruction can be the answer to the question of how to make strong concrete.

To implement the dry ironing method, you must perform the following steps:

1. Apply the cement solution to the fresh concrete surface;
2. The next layer impose sifted cement with a thickness not more than 2 mm;
3. After the dry cement is soaked with moisture, produce smoothing with a trowel.

The result of the implementation of this method should be a solid, flat and durable concrete surface, which has excellent waterproofing performance.

If you decide to produce iron by wet method, then you need to act as follows:

1. Prepare a solution with the addition of sand;
2. Apply the prepared mass to the surface;
3. Using a trowel or a spatula, smooth out the created covering;
4. Dry the surface for 7 days;
5. Grind the surface;
6. Cover the created layer with a polymeric agent.

Council If you decide to use concrete impregnation, you should carefully prepare the surface of the substrate. The main thing in this process is to prevent the final hardening of the solution and carefully level it.

The technology of strengthening the surface of concrete with the help of impregnations is similar to the two previously described methods and involves the execution of the following work:

• Place the dry mix on the wet surface of the concrete;
• Spread it around the perimeter at a time;
• Perform grinding using a specialized distribution machine.

Council When implementing this method, particular attention should be paid to the quality of materials; the higher it is, the more durable the coating will be.

Finally

The uniqueness of this reinforcement technology lies in the fact that you can use it to strengthen only erected structures, and for already existing surfaces. Ironnage can help in the restoration of worn coatings and in strengthening the newly built.

Everyone, even a completely inexperienced builder, will be able to implement this method, the main thing is to follow the technology and acquire quality materials. A video in this article will allow you to learn even more about how you can strengthen the concrete monoliths.
