CONCRETE VS RCC
by Omkar Kr
-: CONCRETE :-
Concrete is a composite material, which is made from a mixture
of cement, aggregate (sand or gravel), water and sometimes admixtures in
required proportions. It is one of the most important and useful materials for
construction work.
When all the ingredients (cement, aggregate, water) are mixed in
the required proportions, the cement and water start a reaction with each other
to bind themselves into a hardens mass. This hardens rock-like mass is known as
concrete.
ADVANTAGES OF CONCRETE:
1.
Concrete is economical than other building materials.
2.
The compressive strength of concrete is very high.
3.
Concrete is very strong in compression.
4.
Concrete can be cast easily into any desired shape.
5.
It possesses a minimum corrosive and weathering effects.
6.
Concrete made with steel reinforcement provides equal
coefficients of thermal expansion.
7.
Concrete can be pumped and sprayed in difficult positions.
8.
It is fire resistant.
9.
Concrete is durable, and have a little maintenance cost which
can be ignored.
REINFORCED CEMENT CONCRETE
Reinforced cement concrete is a combination of concrete and
steel bars(reinforcement bars) where they carry the compressive force and
tension of a structure simultaneously.
As we know that concrete is very strong in compression but weak
in tension and its resistance to tension is also low. That’s why plain concrete
can be used only where the member is in pure compression, but on the other
hand, steel is equally strong in compression and tension. So the combination of
steel and concrete works very well and they are used to take up all the
stresses. Such a combination of steel and concrete is called reinforcement
cement concrete.
ADVANTAGES OF
REINFORCED CEMENT CONCRETE:
1. Reinforced concrete has a high compressive strength.
2. It is economical in ultimate cost.
3. It can be produced easily at the construction site.
4. Reinforced concrete has monolithic characters which gives
much rigidity to the structure.
5. It is durable, fire resistant and almost impermeable to
moisture.
6. The materials used in reinforced concrete are easily
obtainable.
7. Maintenance cost of reinforced concrete structure is almost ignore-able.
8. Due to the flexibility and fluidity nature, reinforced
concrete can be moulded into any desired shape.
9. It is most useful and economical material in constructions
such as footings, piers, damp etc.
