Mahendra Kumar, and G. Chandradhara Abstract The performance of reinforced concrete primarily depends on the bond strength and is defined as resistance to slipping of the reinforcing steel bars from the concrete.

This slipping resistance is predominate mode of failure in predicting the mechanical performance of RCC, particularly to its failure mode and adhesion between steel reinforcement and concrete. In the present study an attempt is made to study the bond strength of structural grade concrete M35 with high strength steel Fe of 12, 16 and 20 mm Fe embedded in the core of concrete.

Also, attempt is made to evaluate the resistance for slippage, rupture behaviour and stress distribution are studied using finite element analysis tool. The study reveals that the bond strength improves the consideration of mineral admixture and also seems to improve with diameter of reinforcing bars for GGBFS binder-based concrete.

The microstructure SEM is also evident for the minimal voids and densification with addition of GGBFS as binder, which enhances the bond strength with a partial replacement of cement. The numerical study closely reviews the experimental investigation. Narasimhan et al. Prashanth et al. The tensile strength of concrete is about one in tenth times the compressive strength of concrete. This negative characteristic is remedied by placing steel reinforcing bars into the concrete to form reinforced concrete RC where steel can resist higher amount of tensile stress and concrete is designed to resist compressive stress.

The performance of RCC primarily depends on the interphase adhesion between concrete and the reinforcing steel which must have a sufficient stronger bond, so the tensile load can be transferred effectively to the reinforcement [1]. The high tensile strength of steel is able to withstand the tensile stresses upon failure of the concrete. In order to obtain complete composite behaviour between the reinforcing steel and the concrete, the tensile stresses must be fully transferred to the steel from the concrete.

This transfer of stresses is facilitated by an adequate bond between the steel reinforcing bars and concrete. The interphase bond strength primarily depends on strength of cement paste and also depends on the bonding surface area size of reinforcement [2]. Based on the literatures, pull-out test [3] is considered for the evaluation of bond strength; an attempt is made to address the contribution of GGBFS as binder for the bond strength improvement.

Binder The OPC 43 grade and finely ground blast farness slag from steel manufacturing industry is used as binding materials.

Fillers The commercially available M-Sand is used as fine aggregates, and 20 mm down size is considered as coarse aggregate. The physical properties are tabulated in Table 1. Reinforcement Fe structural grade steel is used as reinforcing bars with diameters 12 mm, 16 mm and 20 mm embedded centrally in the core of concrete. Varghese Prentice Hall of India.
