– Old and new concrete binder – Increasing the adhesive strength of concrete – Waterproofing of concrete structures – Use in flooring to increase wear resistance and prevent wear – Use in tiling and ceramic floor work (mixed with tile adhesive that increases the durability of the tile for years).
It is a type of ready-made powder mortar based on cement. According to any circumstances, the implementation of a half-finished concrete section may be abandoned and the concreting to complete and build the structure can be done in another period of time after the final setting of the concrete. These conditions will cause the weakness of the concrete in terms of strength and permeability at the place of concreting, which is due to the lack of connection between the new concrete and the old, so using concrete glue is a suitable option. Concrete glue is a thick, milky liquid that is used as an additive in cement base mortars and as a concrete binder. The strength concrete adhesive is based on a styrene emulsion polymer that is easily spread in concrete and increases the adhesion of mortar components to each other and as a result increases the internal strength and durability and flexibility of concrete or mortar. This product causes the formation of a polymer film in a plastic way. It is in the empty space between the aggregates. Concrete glue has the ability to dissolve in water before it dries, it will not dissolve in water after drying
Physical and chemical state:
Properties and benefits:
– Very high adhesion to the work surface – Resistant to cold and heat cycles – Resistant to structural stresses -Preventing from cracking or becoming damaged
It is supplied in 3.5, 9, 20, 200, 1100 kg bags. Note: The use of less and more than the permitted range of this additive or the simultaneous use of multiple concrete additives must be done with the permission of the experts of the technical department of Granabtan Chemical Industries Company
The exact amount of glue consumption depends on various parameters, including the level of surface roughness, the temperature of the environment, the type of cement, the amount of cement, the type of materials used. 9 percent of the weight of cement used to add to the repair mortar, 3 and 5 percent of the weight of cement used and to add to concrete to increase adhesion to old concrete and reduce permeability is 4 to 6 percent.
Method of Use:
The surface of the old concrete should be free from pollution, oil paint, grease and loose spots. Apply a thick layer of strength concrete adhesive product on the surface of the old concrete. Add 4 to 6% of the weight of cement used to the new concrete. Method of using strength concrete glue for sealing inside concrete: For this purpose, concrete glue can be mixed with a part of water or added to ready concrete. The method of using strength concrete adhesive for use in restoration works: Mix strength concrete glue with water at a ratio of 3 to 1 and apply it with a brush on the section where the repair is done. Or add 3 to 5 percent of cement to the repair mortar and apply it. Please note: In order to increase the efficiency and increase the adhesive strength, mineral thickeners such as talcum powder and carbonate are not used, it may have a drop of water due to being in the packaging container and being in a stationary state. It should be noted that for each cubic meter of concrete, at least one minute of mixing should be done. It is better to mix concrete glue with water at a ratio of 3 to 1 and then add it to the mixture.
