【 摘 要 】

The investigation was carried out to know the effect of waste steel shavings on the bond resistance between concrete and steel reinforcement using 16mm and 20mm diameter high-yield reinforcing bars. Eighty (80) RILEM specimens, made up of forty (40) cubes each of 160mm x 160mm x 160mm and 200mm x 200mm x 200mm were cast and tested with varying percentages of waste steel shavings, (0%, 1%, 1.5%, and 2%, by weight of concrete) using pull out arrangement. The normal concrete (with no steel shavings) which are ten (10) in number were used as reference. Also, twelve (12) 150mm concrete cubes were cast to monitor the compressive strength of concrete. The results showed that bond strength increased with the addition of 2%, (by weight of concrete), of waste steel shavings.
