Precast concrete one of the major technological advancement in building construction Industry. To know more go through https://blog.builtify.in/2019/10/adavantages-and-disadvantages-of-precast-concrete-builtify.html

2. What is precast concrete?
• Precast concrete or concrete slab are casted concrete in a controlled environment within a factory. Then it is taken to
the construction site and fitted. It really saves a lot a time.
• Precast concrete are prepaired by pouring concete mixtures into wooden or steel moulds with wire mesh or rebar
and then dried. Then the mould is removed and the desired stucture is obtained.
• As it is done in through moulds you can get any designs upon these concrete stuctures.
• Those days are gone when people use concrete only for their functional purpose. Now in lifestyle focussing society
people are more eager to design their houses. So people are interested to have some designs upon the concrete slabs
or structures.

4. • These precast concretes are reinforced with wire reinforcement or fiber reinforcement when made for building
construction, but reinforced with steel cables when made for bridges .
• These wires and rebars give strength to concrete by providing it required tension.
• One of the benefit of precast concrete is that you have not to cure after it is installed. As the manufacturing is
done within the factory curing is also done within that. so the time for curing also can be saved from the
construction schedule.

5. Uses of Precast Concrete?
Precast concrete has a lot of requirements , that's why they have greater popularity. They can be used in buildings
bridges or any small extensions.
Precast concrete are used for making slabs which is used for making walls, roofs, facades.
• colonial housing:-When more no and similar types of house is constructed at a time for any resdential project then
thses precast concrete slabs are very good . They makes the works faster by saving time and making sure the quality
of each room made is equal.
• Hospital building:- In hospitals we have seen many room sections are required for different purpose. So the
contractors need to construct a lot of walls which is very time taking, for this type of construction precast concrete
slabs are great to reduce the construction time.
• Small retail shopping buildings:-With increase in income people are moving towards retail concept. So the retail
shopping buildings are booming like anything. Many investors invest in constructing these shopping buildings to get
rental benefits. But with these precast concrete these retail buildings can be easily made with less time and also
they are good resistant to fires.

6. Advantages of Precast Concrete
Quality as per Industry Standard:-
As it is fabricated within the factory it’s quality is always maintained. If it is done outside then the quantity of water
cement ratio changes varying it’s quality. Also when the concrete is poured sometime the gravel and and liquid get
separated reducing the quality of concrete.

7. Cost effective:-
When you are constructing large structures of concrete a huge amount of labour is required. And labour cost itself
constitutes a huge part of construction cost. If instead of that precast concrete is used then then it will be more cost
effective.

8. Durability:-
As there quality is maintained while manufacturing they are more durable than the in-situ constructed concrete
structures. Here rod quality cement quality is maintained and the concrete is manufactured according to the industry
standards which gives better durability to concrete structures.

9. Aesthetics:-
These days are gone when people just want a wall and roof or only safety purpose. But with the increase in income
people are focusing on aesthetics of their house. Aesthetics in precast concrete can be well achieved through precast
slab. We can pre-order what designs we want in that slab. In in-situ construction it is difficult to achieve aesthetic look.

10. Sustainability:-
Precast concrete are more sustainable that the in site concrete construction. As it is made within the controlled
environment every perspect of manufacturing can be controlled.
In site the condition of labours are very harsh, but in manufacturing unit their condition can be maintained well. Debris
is one of the major issue at construction site . In precast slabs there is minimal chance of creation of debris which leads
to cost reduction and sustainability.
