1 Introduction
The technology of U-Boot Beton is inspired from Human Bone structure to create the voided
slab using cement concrete and steel.
U-Boot Beton is a recycled polypropylene formwork that was designed to create two
way voided slabs and rafts foundation. U-Boot Beton is used to create slabs with large span
or that are able to support large loads without beams.
A lightweight, cellular concrete made by infusing an unhardened concrete mixture with
prepared foam or by generating gases within the mixture. advantages compared with tradition
play on cement systems those and light weight training or fully faceted to win slabs the
traditional clay cement or polystyrene floor slab.

The traditional clay cement or polystyrene floor slabs normally consists of mono directional
beings that discharge stresses on to the main beings from these two pillars and finally the
foundations the full plate floor slabs instead are made from monolithic reinforced concrete
casts in which the structure is able to bi-directionally transmit loads directly to the by using
U-boot and lighter slab structure is obtained capable of splitting the stresses in any direction
transferring them directly to the penance to simplify the concept we could imagine a series
of double teams of alongside the other and arranged as a premise all stresses will be
concentrated close to pillars where the suitable full section gets left in this way floor slabs
with mushroom like files for the repose in modern people specificity being that the
mushroom is embedded in the floor.

to keep the specific distributed limitations as well as reducing their number benefiting for more

beams structures would need to be avoided typically slab solution is sort together with
savings in those concrete and weak the U-boot beton building system is particularly suitable
for the construction of high-rise village hospitals commercial centres school buildings parking
management residential and industrial buildings.
In case of raft foundations having a greater inertia U-boot makes it possible to implement
sweaters with a better performance given the same concrete used the grounds are found to
have a low carrying capacity furthermore be possible to eliminate or reduce complex and
costly foundation pockets. Laying of avoided two-way elements is swift and simple the
reinforcement and Uboot elements are laid out on top of the decade according to design
specifications ready to receive the concrete casting the layout does not require specialised
personal the correct distance between the elements is assured by a spacer jumped equipped
with a graduated scale by means of which the widths the o beams being formed with the
casting can be rapidly determined at the top this joint gets inserted in specific looking for
difference provided on the upper surface of the Uboot the entire operation is precise handy
and rapid once the concrete is poured avoided structure is permanently embedded providing
the structure with the desired shape on the technical timing for the setting having last the
backing will be dismantled the intros service will prove to be completely smooth formwork
can alsobe used in combination with predominate facing the voided load directly on te plains
and completing the finishing casting.
1.1 Parts of U-Beton
The U-Boot beton is named of the whole element which is used in the slab,but they have
some parts which is used to connect two consecutive U-Beton structure while installing the U-
beton.
There are mainly three parts, of U-Beton system
I. Spacer:-Spacer is used to connect two consecutive U-Beton while installing the
Beton ,Which helps to fix the position of U-Beton.
The rigid interconnection ensures perfect geometric compliance with the
design as well as with the bearing capacity of the formworks when of the operators
casting under the pressure of the concrete, the weight of the operators and equipment.

2 Installation process
The installation process of u-boot system is mention below as.
Step:1- The entire slab surface is covered on a mold surface with wood cover (or similar
systems).
Now place the lower reinforcement over the formwork .
Fig:12-reinforcement done over formwork.
Fig:11-formwork ready with lowerreinforcement

22. Dept. Of Civil Engineering,CIEM 22 |
P a g e
Step:2- Now the place the U-boot system above the lower reinforcement at the specified
interval provided by the horizontal lik connector or by spacer.
Be assured that beton system is connected by spacer, which held he position of beton system
is fix that helps to distribute the stress equally over whole span.
Fig:13-Placing ofbeton systemdone over lower reinforcement.
Fig:12-placedu-beton over lowerreinforcement

23. Dept. Of Civil Engineering,CIEM 23 |
P a g e
Step:3-Now complete the process to place the lower reinforcement over the beton system.
The reinforcement make over perpendicular to each other in the direction
.

24. Dept. Of Civil Engineering,CIEM 24 |
P a g e
Step:4-Now pouring concrete of will be done.
Pouring of concrete should be done in two steps, and the thickness of the roof is drained
vertically to avoid the floating of the u-boots.
The first stage of concreting is done using the super-lubricant. The concentration of concrete
is to the extent that it covers the entire bottom layer, and in the second stage, after the initial
fixation of the bottom concrete, the upper layer is concreted.
Fig:15- pouring concrete done.
At the completion of the concreting process, the u-boot is completely buried in this space and
the upper surface is delivered in a traditional, polished way.

3 Applications
This technology is used to create the slab of high Rise Building, Commercial Building,
hospitals, Multilevel parking building and etc.
This is also used in the construction of Raft Foundation,where the soil have low bearing
capacity. By using this in raft foundation it’s gave great bearing capacity over which can do
heavy construction .

3.1 In Raft Foundation:- Among the various foundation types, rafts are one of
the most well known . They are used above all in ground conditions with little
bearing capacity, or with poor quality soil, large thicknesses must be used which
increases the construction cost.
in raft foundation we can use this technology to increase the
bearing capacity of soil over which can do heavy construction.
It is 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.

4. Advantages
1. INCREASED NUMBER OF FLOORS
Possibility to gain floors at the same building height (towers) and building volume.
2. LARGE SPAN AND GREAT ARCHITECTURAL FREEDOM
Larger spaces.
3. REDUCED SLAB THICKNESS
Thinner slabs but with equal loads and clearances, or bigger clearances with an equal thickness.
4. NO BEAMS BETWEEN PILLARS
Flat soffit for greater flexibility when installing systems.
5. REDUCTION IN THE NUMBER OF PILLARS – OPTIMISATION OF THE SECTION OF
PILLARS
Facilitated use reallocation. Wider bays.
6. REDUCTION IN THE OVERALL LOAD OF THE STRUCTURE WEIGHING ON THE
PILLARS AND THE FOUNDATION.
7. REDUCED FOUNDATIONS – LESS DEEP FOUNDATION EXCAVATION
Lower costs for foundation excavations. Less excavation.
8. IMPROVED ACOUSTIC BEHAVIOUR
Less acoustic transmittance.
systemboot-utheofbenefitsEconomic4.1
 Reduce the consumption of concrete and fittings compared to alternative systems
 Optimal use of indoor space by reducing the number of columns.
 Possibility to provide additional parking lots to remove additional columns
 Less cost-less formatting than other torpedo systems for removing the pendant beams in high
openings
 The flatness of the lower level of the slab, which leads to ease and reduces the cost of
plumbing and cutting under the ceiling.
 No need for a false ceiling and reduce the cost of installing a false ceiling if necessary.
Systemtboo-utheofAdvantagesTechnical4.2
 Possibility to remove beams between columns or use hollow beams that provide optimal column
layout
 Reduce the number of columns.
 Improved design of the reverse plan for the removal of intermediate beams.

29. Dept. Of Civil Engineering,CIEM 29 |
P a g e
 The significant increase in the hardness of the roof slab with its slight weight gain makes it
easier to control the ceiling, allowing the spacing of the columns and the implementation of
large span structures.
 Improved roof performance in terms of sound insulation and plate vibration.
 Reducing loads on the soil (if used in the foundation of the U-boot ) and the possibility of
removing or reducing the number and dimensions of the piles in loose soil
Benefits of the architecture of the u-boot system
 Provide larger spaces Freedom to act more in architectural design.
 Possibility to change user spaces after design and construction.
