Hydrophobic cement is cement that has been treated with additives during manufacturing to make it water-repellent. This allows it to better resist moisture and have a longer shelf life. The cement particles are given a chemical coating that prevents water absorption. Hydrophobic cement is used in constructions exposed to water like dams, sewage treatment plants, and marine structures as it is not affected by high humidity. It also improves the durability of concrete in these wet applications.

Hydro = 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.

4. 4
 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
