Suitability of Steel as Reinforcing Material Many traditional materials such as bamboo and natural fibres have been tried as reinforcement in earlier times. But steel is found to be the most appropriate form of reinforcement. It is the most suitable reinforcing material in R.C.C. because of following reasons : 1. Steel is very strong in compression, tension, shear, and torsion. 2. Concrete develops a very good bond with steel. 3. Steel is ductile in behaviour. More ductility means more elongation of steel before failure. 4. The steel bars can be cut, lifted, and welded easily with commonly available tools and machines. 5. Steel has a longer life. 6. Steel is easily available. Steel reinforcement has various advantages as listed above, which make it a suitable reinforcing material. However, steel has a few disadvantages which are listed below. 1. The biggest disadvantage of steel reinforcement is rusting. If concrete is porous or if the cover to the reinforcement is not sufficient, stee...

14 Principles of Management BY Henri Fayol A principle refers to a fundamental truth. It establishes cause and effect relationships between two or more variables under a given situation. They serve as a guide to thought & actions. Therefore, management principles are the statements of fundamental truth based on logic which provides guidelines for managerial decision making and actions. These principles are derived: - On the basis of observation and analysis i.e. practical experience of managers. By conducting experimental studies. There are 14 Principles of Management described by Henri Fayol. Division of Labor Henri Fayol has stressed on the specialization of jobs. He recommended that work of all kinds must be divided & subdivided and allotted to various persons according to their expertise in a particular area. Subdivision of work makes it simpler and results in efficiency. It also helps the individual in acquiring speed, accuracy in his performance. Specialization leads to e...
