Reinforced Cement Concrete
Reinforced concrete, or RCC, is concrete that contains embedded steel bars, plates, or fibers that strengthen the material. The capability to carry loads by these materials is magnified, and because of this RCC is used extensively in all construction. In fact, it has become the most commonly utilized construction material.
Advantages of Reinforced Concrete
1- Reinforced concrete has a high compressive strength compared to other building materials.
2- Due to the provided reinforcement, reinforced concrete can also withstand a good amount tensile stress.
3- Fire and weather resistance of reinforced concrete is fair.
4- The reinforced concrete building system is more durable than any other building system.
5- Reinforced concrete, as a fluid material, in the beginning, can be economically molded into a nearly limitless range of shapes.
6- The maintenance cost of reinforced concrete is very low.
7- In the structure like footings, dams, piers etc. Reinforced concrete is the most economical construction material.
8- It acts like a rigid member with minimum deflection.
9- As reinforced concrete can be molded to any shape required, it is widely used in precast structural components. It yields rigid members with minimum apparent deflection.
10- Compared to the use of steel in the structure, reinforced concrete requires less skilled labor for the erection of the structure.
Disadvantages of Reinforced Concrete
1- The tensile strength of reinforced concrete is about one-tenth of its compressive strength.
2- The main steps of using reinforced concrete are mixing, casting, and curing. All of this affects the final strength.
3- The cost of the forms used for casting is relatively higher.
4- For multi-storied building the RCC column section for is larger than steel section as the compressive strength is lower in the case of.
5- Shrinkage causes crack development and strength loss.
