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 thicknesses, they will face cracks or separation.
Therefore, if the cement-based repair materials meet the requirements of mechanical strength and adhesion in the structure, they will have a higher priority for repairing concrete sections. In this regard, various repair products have been designed and presented to the market in Abadgaran Building Knowledge-Based Chemical Company.
ABAREPAIR-F high strength concrete repairer
ABAREPAIR-F is one of the cement repair materials in the design of which polymer fibers have been used. The design of this material is such that in addition to high adhesion to a variety of surfaces and materials, especially concrete, it can be used to repair cement sections in large dimensions and up to 50 mm thick.
Due to the constituents, quality and ease of implementation of ABAREPAIR-F, this restorative material can be used in all projects and is also used for repair and reconstruction of concrete surfaces in large dimensions and high thicknesses.
Other advantages of ABAREPAIR-F
include adhesion to the substrate, sealing, concrete repair, flexibility, durability, resistance to weathering and thawing and freezing cycles, no shrinkage or shrinkage, and high mechanical strength.
ABAREPAIR-F high strength concrete repair applications
This material can be used in general applications, 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 of this product include filling non-structural joints and cracks, cavities between bolts and musculature in tanks and water structures. Also, due to the presence of strong materials in concrete restorative compounds, it can also be used to strengthen concrete structures. used.
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.
Compared to other restorative mortars, ABAREPAIR-F can be used in thicknesses up to 50 mm and for repairing structures of some damaged concrete sections. This product has more compressive strength compared to other cement repairers.
Method of Use
The surface should be clean, firm and free of grease, dust, paint, oil and loose particles.
Depending on the required performance and thickness of the implementation, it is recommended to add about 4.5 to 5 liters of water to each 25 kg bag. Mixing the powder with water should be done using an electric mixer (drill + blade). The bucket or container in which the powder and water are mixed should be proportional to the speed of work and the volume of mixing. Always add the powder slowly to the water and make sure that the electric mixer is on when the powder is added to the water and that the mixing process continues until a uniform and homogeneous mixture is obtained.
Be sure to moisten the underlying surfaces before applying the ABAREPAIR-F ready mix.
Apply the prepared mortar with a trowel or spatula on wet surfaces.
Depending on the amount of porosity and unevenness of the applied surfaces, about 2 kg of ABAREPAIR-F is required to cover one square meter with a thickness of 1 mm.
Always mix the amount of powder with water to be used in less than 20 minutes at most.
To achieve the desired strength, after all the mortar has semi-dried, keep all surfaces wet for at least 7 days by spraying water or using a wet sack.
