TYPES OF CEMENT
Name of structure
|
Name of cement
|
Why
|
Construction and masonary work
|
Ordinay Portland cement
|
As it consists of silicates of alumina and calcium carbonates
|
Marine structures and dam construction
|
Portland pozzalana cement
|
It consists of gypsum and pozzalanic materials which gives it power
of hydrating cement
|
Construction of pavement
|
Rapid hardening cement
|
It has high strength because of the presence of Tri-calcium silicates
in high amount in OPC.its initial setting time is 30 minutes and final 600 minutes so used for rapid
construction projects
|
Underwater construction and construction in rainy seasons
|
Quick setting cement
|
It consists of clinker and aluminium silicate which increases the
hydration power of silicate.its initial setting time is 5 minutes and final
30 minutes
|
Construction of chemical plants and wind turbine plinths
|
Low heat cement
|
It produces low heat during setting time and it has reduced heat of
hydration.
|
Effluent treatment plans , chimney , water storage , cooling towers
|
Sulphate resisting cement
|
As it reduces sulphet attacks in concrete
|
Seawater construction
|
Blast furnance cement
|
As it is highly sulphate resistant
|
Construction of workshops
|
High alumina cement
|
It contains high amounts of alumina and lime and can be subjected to
high temperatures
|
Construction of traffic barriers and swimming pools
|
White cement
|
As it has good colour
|
Tunnel and submerged construction
|
Hydrophobic cent
|
As it contains clinkers with water repellent film substances and so
it resists hydration process.these chemicals form a layer on the cement
particles and do not allow water to mix andstart the hydration process.
