What is rebar implant adhesive or reinforcement implant?
Rebar and bolt implant adhesive is one of the most widely used goods in the construction industry, which is effective in all structures with a variety of uses. Since this rebar implant adhesive is made of chemical base adhesives, there will be no mechanical stress in the whole structure that leads to expansion, so it is a good option for use in holes with sharp corners and in any type of concrete with any type of compressive warp. Although there are various types of bolt and concrete planting adhesives on the market with a variety of uses (including capsule bolt adhesive, cartridge rebar adhesive and volumetric and kilogram rebar adhesive), they are all made from a base compound that is a type of resin. Epoxy rebar and bolt implant adhesive has different applications, some of the common application ideas of this adhesive are:
Rebar plate roll
Install the base plate
Hollow block connections
In addition, sometimes for reasons such as design and execution errors, connection of old concrete to new, change in use of the structure, operating conditions or strengthening and improvement of the structure is necessary to plant rebars or bolts; This is where rebar planting companies such as Afzir enter the field. Afzir IEATM two-component rebar planting adhesive with high mechanical and chemical stability is a very good option for planting rebars and anchor bolts in concrete and installing and stabilizing metal parts.
The resin and hardener used in the structure of IEA adhesive make this adhesive not shrink in size when hardened and has excellent adhesion to building materials (whether steel or concrete) and more importantly; By using it, the load on the structure in that part can be significantly increased.
Also, due to the excellent adhesion of IEATM rebar implant adhesive, the hole diameter and restraint length required for rebar implantation are smaller compared to cementitious base materials, thus making drilling operations easier.
What are the advantages of using rebar and bolt implant adhesive?
To plant rebar or bolt, we are required to dig a hole. But we all know that these drilled holes can sometimes be problematic. Rebar implant is a fluid chemical that flows completely through the hole at the very beginning. This adhesive fills the entire space of the hole as long as it completely connects the rebars to the main structure. In this way, the adhesive for planting rebar and bolt insulates air, moisture and water.
You can use mechanical anchorage to plant the rebar. Mechanical anchors are physical parts that are planted deep in concrete to connect a rebar or bolt. But mechanical anchors are limited in either length or diameter. They cannot provide the maximum load capacity of structures. But with rebar and bolt adhesive, you can work at an almost unlimited depth of concrete structure. You are allowed to make perfectly deep holes to plant the rebars as tightly as possible. This feature is one of the advantages of strengthening the structure by planting rebar, which you can increase the load bearing capacity of the structure by planting deeper rebars.
Other properties and advantages of epoxy rebar paste or adhesive compared to other adhesives include the ability to create thicker holes. This adhesive flows easily into the volume of the hole and completely clogs it. In this way, you have the ability to plant completely thick rebars with very high load bearing.
What type of cartridge with how much capacity do you need to inject the adhesive?
choosing the best rebar adhesive is one of the key points in the development of concrete structures. In any case, the structure of concrete buildings is different from each other. Therefore, the amount of rebar and bolt implant adhesive used in them has a specialized and functional calculation method. At Afzir Group, we have designed the product packaging capacity according to the resin mixing ratio and, of course, the full perspective of the market needs in public project and it has presented its product in the form of cartridge rebar implant adhesive in two types of packages.
Cartridge rebar implant adhesive package is suitable for low consumption and meeting the professional needs of small projects. In contrast, the bulky package offered with a significant percentage of rebar and bolt implant adhesive is offered in the form of kilogram packages, which is perfectly suitable for the professional activities of large construction projects.
At Afzir Company, we try to be able to provide a complete range of packages that have a sufficient volume of adhesive for various types of rebar planting in civil operations. For this purpose, various types of cartridge rebar implant adhesive packages are offered in the sizes of 300 ml, 345 ml, 420 ml and 600 ml.
Industrial grade with packaged bulk form for participating in industrial activities is a complete package of 15 or 30 kg. These bulky packages provide enough adhesive for a large number of large civil operations.

Method of calculating the amount of rebar adhesive used
Afzir Group has designed a comprehensive and completely accurate system for calculating the consumption of rebar and bolt implant adhesives. Using this system, you can easily estimate the amount of volume required for the project to be more careful in purchasing rebar adhesive.
In rebar planting operations, if you intend to use chemical inhibitors, you must calculate the amount of adhesive required by the project before any technical action. However, the amount of adhesive used is different for threaded and simple rebars. Calculating the amount needed for a project is a key strategy. Because if the glue for implanting the cartridge rebar is exhausted and the holes are not filled, you can easily use another cartridge that you have cleverly prepared in advance. Otherwise, there is a risk of drying of the low glue in the holes, which is definitely an unfinished and dangerous operation for the continuation of the project.
On the other hand, when you anticipate the amount of rebar adhesive to use, you will avoid buying extra glue. In this way, you will avoid more waste and higher costs. Afzir has cleverly designed an online calculator to support its customers. By entering simple but accurate information of this calculator, you can calculate the volume of glue you need by completely estimating and proposing the number of cartridges used.
To work with an online glue calculator, you need to define several parameters. These parameters include the following:
Introduce the bed in which the chemical inhibitor is to be installed. This bed, whether stone or concrete and even brick structures, have different conditions.
You should introduce the type of rebar, whether it is threaded rebars or simple rebars, and even the type of bolt rebar bases.
The diameter of the hole created
Depth of embedded rebars
Number of inhibitors
With this information, the online calculator quickly enters the calculation process and easily estimates the number of cartridges required by the project for the amount of rebar and bolt implant adhesive used. The criterion of the online calculator is to reach the number of cartridges required by the project based on the input parameters such as the size of the inhibitor, the type of inhibitor, the embedding depth and diameter and the number of holes. The method of calculating the depth of rebar and bolt planting is influential in the final results of this simple calculation. Finally, you are faced with the general information of the amount of cartridge rebar implant adhesive and you should prepare a sufficient amount with this simple calculation in mind.
What is the price of rebar adhesive?
Rebar and bolt implant adhesives are new ideas with a modern design approach to modern structures. Ideas that have been able to revolutionize the level of our construction. The use of rebar and bolt implants is now a new construction idea, and its global market is growing. The global market value of chemical inhibitors, such as market bolt implants, is estimated to be around $ 870 million by 2020. Of course, this market is growing and we expect the annual market value of chemical inhibitors to increase by 4.1% per year by 2028.
Currently, the demand for the use of chemical inhibitors is increasing. However, engineers are aware of the advantages of these chemical compounds over a variety of mechanical anchors. The growing construction market in the United States is a striking example of the level of acceptance. According to the annual report of the American Society of Civil Engineers (ASEC), some 231,000 of the 617,000 bridges in the country need major repairs. Certainly, this one review of existing structures is enough to predict the growing market level of the use of chemical anchors in the United States. However, the selection and use of chemical anchors versus mechanical ones depends on various factors such as the construction project space, installation environment, information and technical understanding of the consumer.
The price of rebar planting adhesive largely depends on the total volume of raw materials produced. In any case, these compounds are direct products of factories in which they supply raw materials at reasonable prices. The price of raw materials has a direct effect on the price of rebar and bolt implant adhesives. We should not overlook key factors such as access to resources, government policies for the supply of chemicals, transportation costs, and the impact on oil prices in all global markets for international transportation.

To start planting rebars, reinforcement and bolts, we must make a hole with a suitable depth in the concrete surface. The size of the hole created should be large enough to ensure that sufficient amount of rebar and bolt implant adhesive flows around the anchor. Note that the depth to the width of the hole created should have a small space for the free presence of glue flow. However, the raised wall of the rebars or bolts always prevents the adhesive from flowing.
If the holes drilled for rebar implantation are permeable, the rebar implant adhesive and the cast bolt will seep into the underlying layers. We definitely do not intend to fix the rebars in the underlying layers. In this case, we have lost a significant amount of rebar adhesive. This is more common in brick structures and less common in concrete.
Then, just before planting the rebar or bolt, you must pour enough glue into the drilled hole. By placing the rebar inside the hole, the planting operation is almost complete. At the end of the work, you have to wait for the glue to harden. The rebar and bolt implant adhesive penetrates completely into the space of the holes created and closes all these holes and will provide insulation against air and water.
bolt implantation methods using chemical inhibitors
Prepare the drilled hole
To make the hole, you must use special drills that can penetrate the concrete. Drill a hole with the required diameter and depth in the preliminary building plan drawings.
After digging, you must remove the dust from inside the hole. To do this, use compressed air for at least four seconds inside the drilled hole. Make sure that the compressed air used is oil-free and make sure that the air has reached the end of the drilled hole completely.
Clean the wall inside the cavity with a special nylon brush. The brush should hardly enter the cavity space. If the brush is moving smoothly or its size is not suitable or the brush is worn out and can no longer clean the cavity wall. Therefore, if the brush movement is smooth and without resistance, be sure to replace it with a new brush that has a suitable diameter.
For the second time, send compressed air into the cavity for at least four seconds. It is necessary that the compressed air nozzle has penetrated to the end of the cavity.
Insert the rebar and bolt adhesive cartridge into the special tool for uniform injection of the adhesive.
Remove some glue. Often the glue does not have a uniform volume at the beginning of the cartridge. Remove the glue from the cartridge until it is a good mixture with a uniform color. This removed adhesive, although small in volume, is not suitable for use. The cartridge is now ready for injection of rebar and bolt implant adhesive.
Fill the hole
Epoxy adhesive should be filled from the bottom of the holes. Fill the drilled hole approximately 1/4 the depth of the adhesive. Then gently pull out the nozzle.
Insert the rebars, which can be ordinary or ribbed, into the hole with epoxy. The surface of the rebar must be free of any dust, grease and any impurities.
After inserting the rebars, you have to wait for the glue to dry. During this period, no work should be done on the implanted rebars.
The duration of the work as well as the loading of the rebars until the rebar and bolt implant adhesive dries is available in the datasheet. Read the table and data in the datasheet to achieve the basic and professional results. Any installation defect will cause serious problems in the installation of heavy inhibitors. Poor installation of inhibitors will reduce the strength and safety factor of the structure, which will definitely break the inhibitors by increasing the load on the implanted rebars. In any case, it is necessary to observe the general steps in planting bolts and fittings. Because it is only in this case that we can have principled, strong and completely durable implanted rebars.
All inhibitors must be installed in accordance with the installation method prescribed by the manufacturer. Therefore, in the first step for planting rebars and bolts, you need to study and be fully acquainted with the official installation instructions. Of course, you will need to follow all of these instructions.
