Issues related to the restoration of concrete structures are divided into several sections, the most important of which are periodic repairs, structural maintenance instructions and restoration of damaged concrete parts due to operating conditions. However, it is necessary to mention that despite the increase in the level of design, implementation and supervision standards in construction projects and improving the quality of concrete construction, execution and processing, some structures also need repair operations during construction or after.
According to these standards, the use of materials in the non-manufacturing category (R1 and R2) is usually limited to eliminating surface problems, surface preparation as well as seemingly work-related issues. Due to the applications mentioned in the design of this category of repair materials, features such as adhesion, appearance and durability are preferred to items such as mechanical resistors.

In this type of restoration, the use of cement repairers is usually recommended. Because epoxy-based repair materials, unlike cementitious materials, due to the difference in the coefficient of thermal expansion with concrete, if used in large volumes or thickness, it will face cracks or separation. Therefore, if special concrete repair materials meet the requirements of mechanical strength and adhesion in structures, they have a higher priority for repairing concrete sections.
Special concrete repair is one of the cement repair materials that is known as one of the most effective cement materials in this category. Special remover is a kind of ready-made powder mortar that due to the presence of polymer compounds in its structure, in addition to high adhesion to various surfaces and materials, especially concrete, also makes it possible to make the surface impermeable. This product also strengthens the structure. Concrete is used.
Due to the quality and composition of the restorative material, it is the first choice for creating smooth and uniform surfaces and initial sealing of concrete sections of projects. The soft and uniform texture of this product has a direct effect on the quality of the finished surface, and by consuming it, sealing costs are reduced by reducing and optimizing the amount of sealing coating used. Proper trowel, easy polishing and no shrinkage or shrinkage are the prominent features of this product. Another advantage of this product is that it provides the required requirements with the lowest cost, such as ease of implementation, quality of the finished surface, adhesion to the substrate, sealing, flexibility, durability and weather resistance.
This material can be used for general purposes and inside and outside the building, such as floor and wall substructures before installing various decorative materials, and is recommended for surface preparation before sealing operations. Other uses for this product include filling joints and non-structural cracks, cavities between bolts, and musculature in water tanks and structures. This material is used for leveling and repairing porous surfaces, repairing fractures of concrete or cemented sections, filling concrete unevenness and leveling unevenness caused by error in formwork.
Special concrete repair due to having quality polymer resins, increase the sealing coefficients of the structure and therefore, compared to other cement-based repair materials, has a very high adhesion to the substrate. This product also received an acceptable score in the concrete test. Another advantage of this product compared to other similar products is the superiority of this material in flexibility and ability to crack on cracks and greater resistance to environmental factors, which makes it a very suitable option for the outdoor environment.
How to use special concrete repair
Before applying the concrete repair mortar, make sure that the desired surface is free of any contamination, including dust, grease, oil and loose particles. If the surface is contaminated for any reason, you must first thoroughly wash and clean the surface with sandblasting or water pressure.
If there are weak points on the surface, it should be removed from the surface. Any contamination or weak points on the surface will prevent the surface from bonding properly with the repair mortar and will shorten the life of the special concrete repairer. Also, any grease on the surface will interfere with the adhesion of the concrete restorative mortar to the concrete surface, and after application, there is a possibility of scaling. To mix special concrete restorative powder and make concrete restorative mortar, choose a suitable container that has the capacity of powder and water after mixing. 4 to 4.5 liters of water is required for each 20 kg bag of concrete repair powder.
First, pour the water into the container and slowly add the repairing powder while the electric mixer (drill + blade) is on and continue until a homogeneous mixture is obtained. Note that before applying the concrete repair mortar on the surface, you must first moisten the surface. If the depth of the place to be applied is high, apply the repair mortar in several layers. Consumption of concrete repair mortar is obtained according to the volume of the desired location for execution, but normally about 2 kg of product is required for each square meter in a thickness of 1 mm.
Be sure to moisten the surfaces before applying the prepared mixture. Apply the prepared mortar on wet surfaces with a trowel or spatula.
Always mix the amount of powder with water to be used in less than 20 minutes at the most. After the mortar is half dry, keep all surfaces moist by spraying water for at least 24 hours. It is recommended to apply Extensive surface repair, chrome plating and leveling method using foam.
