Rebar planting glue is a chemical substance that is produced based on epoxy, polyester and vinyl ester resins. In addition to the polymer resins in its composition, the rebar planting glue in concrete also has concrete additives. These additives include softening materials to increase the flexibility of the rebar planting adhesive and reduce the glass transition temperature, fillers that reduce the shrinkage of the adhesive during setting and hardening and strengthen its mechanical properties. The most important feature of rebar planting adhesives, which should generally be present in all different types of these adhesives, includes appropriate viscosity during mixing and installation, appropriate consumption time, appropriate gelling time, appropriate storage time, density and saturation. It is accepted. In general, the resistance characteristics of rebar planting adhesive against static, dynamic and pseudo-dynamic loads are very important. Also, the issue of how adhesives perform in corrosive and acidic environments is a point of attention.

Volume rebar planting glue is usually two or three components. The -component solvent-free type is based on bisphenol A epoxy resin, hard concrete and polyamide, which is designed to plant reinforcement and bolts in reinforced concrete. Volumetric rebar planting adhesive creates very high adhesion on different concrete surfaces, and the high tensile and bending resistance it creates is usually noticed by engineers.

In the method of mechanical restraint, a hole with a diameter of mm larger than the rebar is created and the rebar is placed inside the cavity along with the mechanical restraint. By turning the armature screw, the fins at the end are opened and stick to the wall of the cavity. Although these blades can cause the wall to crumble, but in any case, they are very useful in static works, including the methods of planting bolts and planting reinforcement.

Cartridge planting adhesives are used for planting on concrete, wooden and stone surfaces. Cartridge rebar planting glue is also two-component and is based on epoxy resin or polyester or vinyl ester and the second component is polyamine hardener, which is used to install and plant reinforcement on concrete surfaces. The general belief is that among the three general types of rebar planting glue, the cartridge type is better than the others because it is easy to implement, its error is low, and it shows very high quality. Of course, it should also be mentioned that this glue has a higher price than the other two types.

Rebar planting is an operation that is done to increase the durability and strength of concrete. In fact, today one of the most widely used works to increase the strength of concrete structures is rebar planting. Among the conditions that compel engineers to use this method to strengthen concrete structures are changes in technical specifications and plans for the design and implementation of structures, changes in usage and operating conditions, ease of implementation and availability. Materials and equipment mentioned. The steps of the rebar planting method in concrete, in the order of making holes in the concrete by drilling or sanding on the concrete surfaces, washing and cleaning the concrete surfaces and inside the holes created by the blower and air suckers, injecting the rebar planting glue by means of special equipment at a sufficient depth and finally installing the rebar on the concrete structure.
