REINFORCED CEMENT CONCRETE

REINFORCED CEMENT CONCRETE

      R.C.C is the combination of reinforcement, cement, aggregates and sand, in which reinforcement is provided for taking tensile stresses and combination of cement, aggregates and sand is provided for taking compressive stresses.
      Concrete is very weak in tension but it is strong in compression. Hence cement concrete is reinforced by embedding steel in tensile zone as well as in some cases in compression zone also. it is known as reinforced cement concrete. Reinforced concrete is thus a rational union of concrete and steel combined to act jointly. The joint action of steel and concrete in a reinforced concrete section is dependent on the following important factors-

1.  Bond between concrete and steel
2. Absence of corrosion of steel bars embedded in the concrete
3. Practically equal thermal expansion of both concrete and steel

Advantages of R.C.C

 Advantages of R.C.C

1.  Concrete can be moulded to any shape and hence any architectural shape may be given to the structure.
2. R.C.C. ingredients are easily available.
3.  Monolithic character of structure impart more rigidity to the structure.
4. It is economical in initial construction.
5. Its maintenance cost is partically nil.
6. It  is sufficiently water tight and impermeable if proper controls are exercised during mixing, proportioning, placing , consolidation and curing etc.
7. R.C.C. structures are completely fire resistant.
8. They are durable and not easily affected by atmospheric agencies.

Properties of R.C.C.

      Properties of R.C.C

1.  The co-efficient of linear expansion of concrete and steel are almost same. Therefore no internal stresses are developed in R.C.C due to change in temperature.
2.  The coating of cement on reinforcement protects it from corrosion.
3. Concrete transfers the stresses to steel, which it cannot resist itself.
4. IT provides monolithic and rigid joints.
5. It is not affected by termites and vermins etc.
6. These member can be made to any desired shape.
7. These member are economical than steel members.
8. R.C.C is a watertight material.
9. R.C.C is having less maintenance cost.

R.C.C USES

 Reinforcement cement concrete is commonly used to construct the following elements-

1.  Slabs
2. Lintels
3. Beams
4. Columns
5. Footings
6. piles
