What is RCC & PCC?

Plain cement concrete (PCC) is simply concrete by definition. It is cement + water + fine aggregates + coarse aggregates. It is the ordinary concrete without any kind of reinforcement. Reinforced cement concrete (RCC) is PCC + reinforcement.

How do you make a RCC road?

The steps in the construction of cement concrete roads are the following:

  1. Preparation of subgrade/sub-base.
  2. Placing of formwork.
  3. Batching of materials. ADVERTISEMENTS:
  4. Proportioning of the mix.
  5. Preparation of the mix.
