The definition of structural reinforcement derived from the fourth principle of EN 1504 standard is the use of systems and products that increase or restore the bearing capacity of concrete structures. In other words, based on calculations, design or conditions of use and use, the need to increase the thickness or reinforcement of various elements of a concrete structure (foundation, beam, column or shear walls) by establishing a connection between the existing concrete structure with layers or If the reinforced concrete elements are external, the use of chemical anchors is necessary.
ABABOND RA-500 rebar implant adhesive
In order to create a proper bond between concrete and rebar, rebar adhesives (rebar paste) with different properties can be used, which depending on the conditions of use and acceptance criteria, the highest technical and economic efficiency along with ease of implementation. Get. The definitive solution recommended by the specialists of Abadgaran Company is ABABOND RA-500 planting material ABABOND RA-500 is a two-component material based on highly effective modified epoxy resins for planting rebars and anchor bolts in concrete.
The special type of resin and hardener used in the structure of this adhesive makes it work long even at high temperatures. This adhesive has a high load bearing capacity and can be used in a variety of heavy engineering operations. ABABOND RA-500 has very high adhesion and mechanical resistance and the possibility of planting rebar in conventional and lightweight concrete and protecting them against corrosion and rust Provides.
Features of ABABOND RA-500 rebar implant adhesive
This material has very high load tolerance, excellent chemical resistance and fast and easy implementation. The type of packaging of this material is designed and made as a twin cartridge for ease of mixing components, precision and accuracy of execution. ABABOND RA-500 implant adhesive (rebar implant paste) for implanting rebars and anchor bolts, bonding metal sections to concrete and stone And bricks are used as well as installation and fixing of parts.
The nature of the chemical foundation of ABABOND RA-500 is such that in comparison with other common cases such as polyester and vinyl plaster, the highest adhesion and mechanical strength that leads to the reinforcement of the building is such that it is widely used in heavy engineering operations. In addition, the storage time of these materials is even longer at high temperatures and they are less dependent on the operating conditions. In other words, assuming defects during the application of implant adhesive, the use of epoxy foundation in comparison with the above will lead to better results.
After drilling according to the recommended sizes, the inside of the holes must first be cleaned with wind pressure. The inside of the hole is then thoroughly cleaned using a brush larger than the diameter of the hole to remove loose particles.
Clean the inside of the holes again with wind pressure. Make sure there is no dust, loose residue, water, ice, grease or other contaminants before applying. Lack of proper preparation will reduce the loading capacity.
Contamination such as oil in compressed air will reduce adhesion.
Do not use water to clean vertical holes.
They should be inside the dry hole when the adhesive is applied.
ABABOND RA-500 is supplied as a twin cartridge. The cap must be removed and replaced with a static mixer before use. The cartridge should then be inserted into the appropriate twin gun and the material should be injected by squeezing the trigger. To ensure that the unmixed glue does not enter the hole, after squeezing the trigger several times and removing the initial part of the material, the injection into the holes should be started. The adhesive should be injected evenly from the end of the hole so that air is not trapped inside.
If the length of the static mixer is not sufficient to inject into the holes, the desired length can be reached by using a thin hose and adding it to the mixing static outlet. The hole should be filled with glue about two-thirds of its length. After rusting by mechanical methods and removing any grease or contaminants, place the rebars inside the holes and make sure that the surfaces of the rebars are in full contact with the implant adhesive by turning.
Note: Do not move the rebar into the hole until the implant adhesive has reached its initial setting.
