The reinforcement is a metal rod or rods cooked together, in nets or frames. The main use of reinforcement is the strengthening and strengthening of concrete. The construction uses two types of reinforcement, working and installation. The working reinforcement includes the reinforcement installed in the design, according to the calculation, and the installation reinforcement is used to form with working reinforcement of nets and frames. In most cases, flexible reinforcement is used, of steel that has the form of separate or welded in nets and frames, rods.
Also, in some cases, a rigid reinforcement can be used, which is a corner, rolling double -costs and channels. It should be mentioned that fiberglass, bamboo, as well as other materials can be used as reinforcement. For the production of reinforcement, special reinforcing steels are used that have various characteristics. The most common is the core reinforcement, which is divided into seven classes. Adding reinforcement to concrete ensures their clutch, along the entire area of contact. Clutch of concrete and reinforcement, primarily depends on the characteristics of concrete and the reinforcement itself. In the process of production of reinforcement, to improve its characteristics, the method of hardening and gluing is used, and physical and thermal processing is also done.
