Precast Technology:

Technology

Overview



The

process

involves

manufacturing

concrete

elements,

stutural

and

non
-
structural

,

either

in

a

factory

or

at

site

but

not

at

its

final

location
.



In

Brief
:

This

technology

has

a

‘product

centric

approach’

against

the

‘process

centric

approach’

of

conventional

construction
.


Advantages



Faster

Construction

&

Reduced

Labor

Minimal

Wastage

of

Transportation

Costly

as weight is

Lesser weight

makes the

transportation cost lower with
respect to solid slabs

Low weight / volume
, the
transport costs to the
construction sites are lower
than for solid slabs.

Technology: Equipment for Production
-

Walls

Battery Mold


Consists
of
vertically

arranged, adjustable shuttering
panels


Vertical
shuttering system facilitates the manufacturing of wall elements of
varying

wall
thicknesses


Appropriate
wall thickness is defined by the wall profile system, which is inserted
between the two adjacent
shuttering

panels

Description

Usage


Used for producing
Identical

designed Solid walls, Sandwich walls & Enclosure
Walls: Walls w/o openings or standard openings


Faster

Mode of production

Advancements


Heating system
, integrated
in the shuttering panels, using hot
water


Quicker Concrete Curing Process


Leads to larger production capacity
