Abstract

The bond between concrete and reinforcement is very important to work as a composite behavior of Reinforced Concrete (RC). The several factors which influences the Bond stress in RC are embedment length, diameter of bar, cover, spacing of bars, transverse reinforcement, grade and confinement of concrete around the bars, type of aggregates used in concrete, type of bars and coating applied on bars, if any, for corrosion prevention. Adequate bonding between reinforcing bars and concrete is essential for the satisfactory performance of RC structures. This study primarily focuses to achieve best possible outcome for desired provision of development length in terms of strength and effect of development length on concrete structure for bond stress. The concrete cube design and casting for M20, M25 & M30 grade (7 days, 14 days, and 28 days) carried out and compressive strength is determined. In further study, concrete cube (150mmx150mm X150 mm) with constant embedded reinforcement length of different size diameter (6, 8, 10, 12, 16, mm) steel having variation in development length bar angle from 0, 45, 90, 135 and 180 degree were tested for pull out test on concrete and casting for M20, M25 & M30 grade (7 days, 14 days, and 28 days) carried bond strength results were obtained.
