INTRODUCTIONHydro = Water 

Phobic = against So ,hydrophobic cement has an additive which repells water. 

DEFINATION : Tending to repel and not absorb water; tending not to dissolve in or mix with or be wetted by water.

  Hydrophobic Portland Cement is manufactured on special requirement for high rainfall areas to improve the shelf life of the cement.

The cement particles are given a chemical coating during manufacturing which provides water repelling property and the cement is not affected due to high humidity and can be stored for a longer period .

This has to be obtained on special order from the cement manufactures.

USES In hydro technical construction. hydrophobic cement affect its heat release. Sewage disposal treatments works Water treatment plants Constructions which are expected to be attacked by dissolved chlorides and sulphate ions. hydraulic structures-dams, retaining walls Marine structures Mass concrete works- like bridge footings
