Department of Civil Engineering, SCOE, Pune Department of Civil Engineering, SCOE, Pune ---------------------------------------------------------------------***--------------------------------------------------------------------Among the many structural strengthening techniques, the Abstract - Post-installed reinforcement is widely used in the 2Professor,
world because it is needed in rehabilitation and strengthening works. It helps contribute to the cost effectiveness of construction in general and offers a level of confidence in the structural integrity of civil engineering and civil engineering projects. Engineers must be certain of the performance of the adhesives to be used where the adhesives are used as a bond between steel reinforcing bars and concrete. Rebaring technique in reinforced concrete construction is a method for proper fabrication and placement of reinforcement bars as per the design and drawings for RCC works. The reinforcement bars are mainly patterned over its surface to facilitate proper bonding with the concrete. To determine the strength of the adhesive (Fischer Chemical), we will perform a comparative test between conventional cubes cast with 16mm rods inserted during the casting process and simultaneously casting the same type of conventional cubes and after curing by drilling an 18mm diameter hole to insert 16mm rods along with the chemical. After the curing period, various tests will be carried out including NDT tests, pull-out tests and split tensile test.
technique of planting reinforcing bars has unique technical characteristics.

(4) The process is easy and saves time.
(1) Flexible design and wide application. According to usage requirements, the number and specifications of reinforcements at each point of reinforced concrete structures can be designed according to structural stress characteristics. (2) Positioning is accurate and reliable. In general, reinforced concrete structures need to secure embedded parts when connecting to other structures, but the weak point is that it is difficult to adjust the position of the embedded parts. After adjusting the structure and functions, the position of the embedded parts is difficult to change, the planting pole is flexible, and the reliability is equivalent to that of the embedded parts. (3) Convenient construction.

2. NEED FOR STUDY
1. INTRODUCTION In recent years, new concrete technologies and materials have been widely used in engineering renovation and reinforcement. Chemical rebaring reinforcement technology is a new type of reinforcement and reconstruction technology for reinforced concrete structures. It not only has the characteristics of convenient construction, small working face and high working efficiency, but also has the advantages of strong adaptability, wide application range, good integrity of anchorage structure and low cost. Therefore, it is widely used in building reinforcement and concrete reinforcement projects.

3. AIM
Good bonding between steels by using chemical fixatives as adhesion promoters between steel and concrete only after drilling holes in the fixing area, eliminating the need to drill many holes for fixing reinforced concrete structures can be ensured. This not only damages the original component, but also reduces the effort of the reinforcement technique.
