Reinforced cement concrete is a composite material obtained by combining the basic two components of concrete viz. Cement and Aggregates with reinforcement (Steel). This reinforcement is used to increase the tensile strength of the structure.
Concrete is a brittle material which does not possess any tensile strength, but when reinforced with steel, it acquires tensile strength due to the interaction between the two materials. The percentage of steel in RCC may vary, however, it should be minimum 4% by weight of total concrete volume.
There are many other factors affecting the RCC design and construction such as types of cement, type and size of aggregate, mix proportions, placement methods, curing procedures etc.

Reinforced Cement Concrete (RCC) is a combination of concrete, cement and steel bars. The RCC is used for making buildings. The strength of the concrete is depends on the grade of concrete that we have used. The grade of concrete is decided by the ratio of Cement, Sand and Coarse aggregate in it.
The strength of the concrete increases with increase in cement content and sand-cement ratio.
We can measure the toughness of the material by checking its compressive strength. We use cubes for testing compressive strength. A 150mm cube is cast and then tested after 28 days with a Compression Testing Machine (CTM). If we want to know more about reinforced cement concrete, we can read more about this on this blog.
Reinforced cement concrete is a construction material made by mixing of cement, aggregate (generally sand and gravel or crushed stone), water and chemical admixtures in proper proportions. The following figure depicts the components of conventional concrete.
Concrete is an artificial stone-like material used for various structural purposes. It is made by mixing together cement and various aggregates like sand, pebbles, broken stones etc., with water, and allowing the mixture to harden by hydration. Cement acts as a binder that binds together the aggregates into a solid mass. Concrete is thus obtained by hydration of cement which results in the formation of a binding material in the presence of water. The performance of concrete depends upon its constituent materials, mix design and quality control during production and placement.

Reinforced cement concrete is a composite material composed of concrete and steel. The combination of materials provides better tensile strength than concrete alone. While, the reinforcement in concrete was first introduced by Joseph Monier in 1849, its use in structural engineering dates back to the late 19th century.
There are two reasons that reinforced cement concrete is an important material:
1) Concrete has high compressive strength but low tensile strength.
2) Reinforcement increases the tensile strength of concrete by several times, thus making it ideal for construction.
Reinforced Cement Concrete – RCC or Reinforced concrete or Reinforced cement concrete (RCC) is a composite material in which concrete’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets.
Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed (in tension), so as to improve the behaviour of the final structure under working loads.
In the United States, the most common methods of doing this are known as pre-tensioning and post-tensioning.
This article deals with standard reinforced concrete, where the reinforcement is embedded by casting the concrete around it.
It is obtained by mixing cement and fine aggregate with coarse aggregate, water and admixtures in required proportions. The mixture when placed in specific forms and allowed to cure for required time, produces concrete which is strong in compression and weak in tension. Hence to make the concrete strong in both compression as well as tension, steel is used inside the concrete. This composite material when properly proportioned and mixed and placed in forms and allowed to cure produces reinforced cement concrete (RCC).
The most important factor that makes RCC different from plain concrete is the provision of reinforcement. In reinforced concrete, we use not only steel but also a lot of other materials like aggregates (fine aggregate, coarse aggregate), cement, water, etc.
In reinforced cement concrete, steel is used as reinforcement. It is an important material in structural engineering and architecture. It is also called reinforced concrete or ferroconcrete.
It is a composite material that consists of two main components:
A binding matrix (usually cement paste)
Reinforcement (usually steel)
The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the concrete sets. Sometimes other forms of reinforcement such as fibers, beams and plates are also used. The reinforcement can also be placed passively around the concrete.
