Reinforced Cement Concrete (R.C.C
)
RCC is the most
integral component of 21st century civil engineering, reinforced cement
concrete. The RCC has elevated the world to a higher level.
According to the Oxford Dictionary, reinforced means "make it
strong." So we make concrete with steel strips.
What is cement ?
Cement is a well-known building material as a mandatory space occupied
in construction work.
China is currently India's second largest cement producer.
What is concrete ?
Inorganic materials, known as common concrete cement, are mixed with
water and combined with natural stone piles and natural stones that can be
boiled or crushed.
Why the combination of rust and material?
a)The co-efficiency of linear expansion of concrete and steel is almost
the same. Therefore no internal stress is established in the reinforced
concrete due to the change in temperature. ( Materials expand or contract when
subjected to change in temperature .... An average value for the co-efficient
of increase in light of concrete is about 10*10^-6/c, & steel for
7.2*10^-6/c. )
b) The coating of cement on the steel bars protects them from rust and
does not create adverse chemical effects.
c) The surface of the steel rod is set very quickly while gripping
concrete. Therefore, concrete can transfer stresses to the reinforcement that
cannot be resisted.
Advantages, Disadvantages and uses:
Advantages: Reinforced concrete has the following advantages:
1. It will not rot or rot and will not be attacked by termites.
2. It is economical in terms of cost.
3. Almost no moisture is passed.
4. Its constituents are easily available.
5.It can be easily molded into any shape.
6. It is durable.
7. The structural member can be made with any desired strength.
Cons: Cons of reinforced concrete-
1. High initial cost,
2. Heavier than steel construction,
3. Skilled supervision and workmanship required,
4. Involves additional cost of form-work,
Uses: Reinforced cement concrete is commonly used for the construction
of the following:
1. Slabs,
2. Lintels,
3. Beams,
4. Columns and their footings,
5. Foundations,
6. Precast or cast-in-situ concrete piles etc.
