Question

What is RCC? Write the advantages of it.

Answer 1

Plain concrete has good compressive strength, but less ability to withstand tensile stresses. In such cases, to impart tensile strength steel bars or rods and metal meshes are embedded in the concrete. This is called as RCC. Here the concrete bears the compressive strength and the steel rods bears the tensile strength.

APPLICATION:- Widely used in floor beams, girders, slabs, bridges, etc.

ADVANTAGES:-

1. RCC is easier to make and cast into any desired shapes, which can bear all types of loads.
2.  It possesses greater rigidity, moisture, and fire-resistances.
3. Steel reinforcement also tends to distribute the shrinkage cracks, thus preventing the formation of large cracks.
4.  Its maintenance cost is practically negligible .
