Define Waterproofing Cement:

Waterproofing cement is actually a Portland cement in which we added water-repellent agent. By grinding Portland cement clinker with a film forming substance like oleic acid which is use to reduce the rate of deterioration, by this process we obtaine hydrophobic acid. Unicorn is the best company which is providing portland cement .

Types of Portland / Water Cement:

By American society of testing and Materials there are five types of portland /waterproofing cement .

1- Ordinary Waterproofing Cement:

It is use for general r common purposes
Used for general construction
Used in making of precast cement
Used for prestressed concrete which is not in contact with soils and ground water.

2- Modified Waterproofing Cement:

It produce less heat during hydration
It will be a resister to moderate sulfate
It usually come to same cost as ordinary waterproofing cement cost
Used for prestressed concrete which is in contact with soils and ground water
more efficient for higher sulfur content soils

3- High early strength Waterproofing Cement:

It is called rapid hardening
It is ground finer
Its 3 days compressive strength equal to 7 days compressive strength of type 1 and 2 portland cement
It is use for manufacturing of precast concrete
Used for emergency constructions and repairs
Used for construction of machine base and gate installations

4- Low heat Portland Cement:

Low heat hydration cement
Used where the rate of heat generate to be minimize
Used where the amount of heat generate to be minimize
Used to develop strength at slower rate
Uses in massive concrete construction structures
To build a large gravity dams
To compress the rise temp during curing process where heat is generate at large scale
Pozzolans and slags are examples of this type to control cement temperature
