Bond Performance in Concrete Structures: DE - Softcover

Inhaltsangabe

The bond between concrete and reinforcement is very important towork as a composite behavior of Reinforced Concrete (RC). The several factorswhich influences the Bond stress in RC are embedment length, diameter of bar,cover, spacing of bars, transverse reinforcement, grade and confinement ofconcrete around the bars, type of aggregates used in concrete, type of bars andcoating applied on bars, if any, for corrosion prevention. Adequate bondingbetween reinforcing bars and concrete is essential for the satisfactory performanceof RC structures. This study primarily focuses to achieve best possible outcome fordesired provision of development length in terms of strength and effect ofdevelopment length on concrete structure for bond stress.The concrete cube design and casting for M20, M25 & M30 grade (7days, 14 days, and 28 days) carried out and compressive strength is determined. Infurther study, concrete cube (150mmx150mm X150 mm) with constant embeddedreinforcement length of different size diameter (6, 8, 10, 12, 16, mm) steel havingvariation in development length bar angle from 0, 45, 90, 135 and 180 degree weretested for pull out test on concrete and casting for M20, M25 &M30 grade.
