HOW TO PREVENT BLEEDING AND LAITANCE IN CONCRETE?

Bleeding cannot be completely prevented as it is an inherent property of concrete. But it can be minimized if following precautions are taken.

Preventing Bleeding

• By proper proportioning of concrete mix.
• By mixing the concrete uniformly and completely.
• By using finely divided pozzolanic materials ( as it creates a longer path for the water to traverse and it has a high surface are)
• By using air entrain admixtures.
• By using finer cement or cement with low alkali content.
