Abstract

Abstract: In construction of a Reinforced Cement Concrete (RCC) structure, as per the design requirements, the reinforcement mesh is made by tying the assembled re-bars at each crossing with the help of a tie wire. There are different types of tools for process the re-bar busting like – conventional hook, hand twister, twisting pliers, tying gun. Generally, in India, there is a deficiency of skilled labours and the usage of conventional hook is at most common in construction areas that indirectly disrupting the work efficiency and thereby increases the production cost as well as the work done time. It is very important to introduce a new method for re-bar busting process in Indian construction industry. This project deals with a new innovative method for tying the re-bar and comparison of this different method with ordinary methods based on time consumption on tying the knot, productivity range and health issues.
