RCC BLOCK: LATEST CHOICE FOR A BUILDING CONSTRUCTIONS

Reinforce Cement Concrete block is a versatile building material which is strong in compression as well as tension. The use of reinforcement in concrete highly increases the strength and thus paves a great way for easy and strong construction. It possess steel cores, around which the cement concrete matrix is poured and is also called reinforced concrete or ferroconcrete. It is a composite material in which the inclusion of reinforcement having high tensile strength and ductility, compensates it from low tensile strength and ductility. RCC is used for paving in airports, roads, high traffic areas, tanks, bridges, etc. This can be established as an eminent and latest choice of building material in the construction arena.

REINFORCED CEMENT CONCRETE

In the case of plain cement, it posses a low level of tensile strength which is not so good in the case of buildings and here we need to add a supplement which can enhance the tensile strength and ductility of  the plain cement and thus reinforcement is used. This can take up the tensile stresses developed in the structure. The common type of reinforcement is in the form steel bars which are much stronger in tension.In this, fresh concrete is poured around after placing the reinforced steel and is called as Reinforced Concrete Cement, abbreviated as RCC. RCC is a concrete material, which is made up of concrete and steel enforcement. Generally, in steel reinforcement, the steel bars are placed in the tensile zone of the structure and take up the tensile stresses. It is a versatile construction material which not only increases the tension but also prevents shrinkages.

ACTION OF STEEL AND CONCRETE IN REINFORCEMENT

The composite action of steel and concrete in a reinforced concrete section is dependent on the following vital factors:

• The bond produced between steel and concrete.
• Prevention of corrosion of steel bars in the concrete.
• Equal thermal expansion of steel and concrete.

ADVANTAGES OF REINFORCED CEMENT CONCRETE

Following are the advantages of reinforced cement concrete:

• Strength: RCC possess high strength as well as compression.
• Durability: RCC structures are durable can last up to 100 years if it is laid properly.
• Mouldability: This can be given any shapes easily by properly designing the frame work.
• Ductility: The steel reinforcement imparts ductility to the structures made by RCC.
• Economy: It is cheaper compared to steel and pre-stressed concrete.
• Transportation: The raw materials available for RCC is easy available and facilitates transportation.
• Fire Resistance: These structures are fire resistant as compared to other building materials.
• Seismic resistant: They are highly resistant to earthquakes.

USES OF REINFORCED CEMENT CONCRETE

There are a number of uses by the RCC blocks in construction. Some of the construction sector are following:

• Airports.
• Roads and high traffic areas.
• Bridges and underwater structures.
• Towers and Multi-storeyed buildings.
• Chimneys and Retaining walls.
• Bunkers and Silos.
