This presentation discusses U-Boot Beton technology, which uses recycled polypropylene formwork for construction. It allows for lighter and more economical building designs through large span slabs and foundations. The key components of U-Boot Beton include spacer joints, connection bridges, and closing plates. Installation involves placing reinforcement, then setting up the interconnected U-Boot formwork before pouring concrete. U-Boot Beton provides benefits like reduced material costs, increased seismic resistance, and more flexible architectural designs. It has various applications in buildings like hospitals, parking structures, and hotels.

3. INTRODUCTION
 It is the recycled polypropylene (plastic polymer) formwork technology used
for construction purposes.
 It creates lighter economical design for
structure.
 This is used to construct Two way slab,
large span slab , mushroom slab and
raft foundation in RCC structure.
 It is suitable for high rise building, hospitals and parking management
residential and industrial building.

4. PARTS OF U-BETON
 There are main three parts of u-beton,
I. Spacer joint.
 It is used to fix the position of u-boot
during construction.
 to maintain the rigid interconnection
that ensure perfect geometric compliance
with design as well as bearing capacity of
formwork.

II. Closing plate.

6. Types of u-beton
 Generally two type of u-boot beton ,
I. single u-beton:-it have only upper u-beton with foot and spacer.
where,
H = height of up U-Boot.
P = height of foot.
S = Spacer height.
 Single U-Beton is available of various up beton height and foot height of base
dimension (52 cm x 52 cm).

7. II. Double u-beton-It’s having both upper and lower part of u-boot with foot
and spacer.
 This is also available in various size of up u-boot,down
down u-boot and foot height.
where,
P= foot height.
H= Total height of upper u-boot and lower
u-boot.
 The working dimension of double u-beton is (52cm×52cm).

8. Installation Process
 The installation process for the u-boot is showing below as step wise,
 Step-I:-place lower reinforment
above the formwork.
 Step-II:-Now place the u-boot above
the lower reinforecement at the
specified intervals provided by the
horizontal link connectors.

9.  Step-III:-Now complete the upper
reinforcement which above the u-beton.
 Step-IV:-Now pouring of concrete is
being done.

reinforcement.

10.  Step-V:-Now concrete is poured and
slab is ready.
Now after setting of the concrete we
We will un-propped the formwork.
 The final slab is looking below as
image given.

11. Applications
 It is used to create large concrete span which having great bearing capacity.
 It’s increases the spacing of columns which gives major benefits.
 It is used in High Rise Building , Commercial building , Hospitals , Parking Lot
etc.

12.  It can be is also used in raft foundation due
to the following reason,
I. To increase the bearing capacity where
soils having low bearing capacity.
II. Can make heavy construction above this
foundation.
III. Concrete saving as compare to making
general raft foundation.
IV. Provide great bearing capacity with lower
thickness of slab.

13. Advantages
I. Economical Advantage.
 Reduction in cost of slab.
 Reduction of Concrete consumption.
 Reduction of Steel consumption.
II. Technical Advantage.
 Fire resistance.
 Reduces effective mass of slab.
 Reduces no. of column.
 No beams b/w pillers.
 Possibility to remove beams
between columns.

14.  Extreme earthquake resistance.
 Control vibration.
III. Architectural Advantage.
 Provide larger space.
 Freedom of architectural design.

15. Conclusion
 By using this technology we can save more concrete and steel by that structure is
more economical for us.
 Less use of iron in the slabs, pillars and foundation up to a total of 15% .
 There are anti-seismic advantages connected to reduced building weight slimmer
pillars and foundations, there are low chance of seismic effect on the buildings.
