The blast furnace slag cement has very low permeability and provides good resistance to chloride and sulphate attack which is present in seawater. The blast furnace slag cement is widely used in the marine structure.

Blast furnace slag cement other uses:$

Used for structures meant for water retaining such as retaining wall, rivers, ports, tunnels for improvement in impermeability.

Used in mass concreting works such as dams, foundations which require low heat of hydration.
