How to Reduce Bleeding in Concrete?

The tendency of water to rise to the surface of freshly placed concrete is called bleeding. Bleeding causes the formation of a porous, weak and non-durable concrete layer at the top. It also increases the permeability of concrete.

Bleeding can be reduced by adopting the following measures:

  • Using pozzolanic materials.
  • Proper proportioning of ingredients and uniform & complete mixing.
  • Using air-entraining agents.
  • Using finer cement.
