The workability is very tough when using stones for building the structure. Before the modern era, many buildings were constructed using stones, and there is no concrete in the structure.
Moreover, small buildings are constructed by brickwork and random rubble foundations.
At present, many structures, even small buildings, are constructed by reinforced cement concrete.
In 1853, Francois Coignet was known as the first person to use iron-reinforced concrete. He used to build a four-storey building utilizing this technique at 72 rue Charles Michels in the suburbs of Paris.
Reinforced cement concrete is the composite of concrete and steel reinforcement that can resist different types of load such as compressive, tensile, and shear force. RCC having functional resistant capacity against fire.
The concrete can be sustainable against great compressive force, but it has low tensile strength and may fail due to tensile stress. So the reinforcement material, which is strong in the tensile, has been embedded in concrete to increase the tensile strength.
The primary purpose of using reinforcement in concrete is to make the concrete strong against tensile force.
Steel has a very high tensile strength compared with any other materials. Moreover, steel and concrete have very similar thermal expansion properties.
Below materials can be used in concrete instead of steel, but many quality and durability tests have to be conducted to ensure whether it is good or not.
The reinforcement material should contain the following characteristics.
We can not say the below points as disadvantages may we should take more care while working by RCC.
The following factors may affect the strength and durability of reinforced concrete.
