Betonbloc - Sedpa

GENERAL POINTS
Aerated concrete
BETONBLOC® , a building material particularly
designed for carcassing and light finishing work,
has exceptional properties and qualities which
make it a product completely suited to
modern building methods.
Composed of millions of miniscule closed cells
filled with air, BETONBLOC® is
distinguished by:
Lightness (density of 400 to 700kg/m3).
Compressive strength (CS):
average values measured on
25 to 50Kgf/cm blocks
A remarkable level of thermal insulation.
Exceptional thermal inertia (thermal comfort)
Excellent burning behaviour.
Easy shaping.
Due to its density, it is classified as a light-weight or extra-lightweight concrete.

USE
Aerated concrete blocks are used for
the construction of internal and external
bearing and non-bearing walls.
They are recommended for all types
of construction: houses, apartments, offices,
garages, shops, schools, hospitals,
industrial and agricultural buildings, etc.
4

Installed vertically, these components can
be used as bearing walls.
BETONBLOC® is generally used for
its excellent thermal insulation:
particularly recommended for keeping buildings
cool during the summer.
As aerated concrete is easier and quicker
to work with than traditional materials,
it greatly reduces construction costs.

PROPERTIES
DENSITY
The dry density of BETONBLOC® SEDPA
is between 400 and 700kg/m3.
The equilibrium moisture content of the aerated cement
must be maintained +/-3% during working.
For construction work, the following densities
must be adhered to:
Cement walls: from 400 to 700kg/m 3
Brick walls: from 530 to 700kg/m 3 .
The European standard EN NF 771-4
qualitatively classifies aerated concrete
according to dry density and
compressive strength.

MANUFACTURE
Manufacturing the blocks
The raw materials are stored in different silos.
The sand has previously been finely ground either
after drying or by humidification (adding water).
The raw materials are pumped from the silos
and are accurately proportioned before being mixed,
with water, in a mixer.
After mixing, the mixture is poured into moulds,
filling them half full.
The lime/aluminium powder chemical reaction releases
hydrogen, which creates a large number of cells and
greatly increases the density.
The miniscule hydrogen bubbles (cells) are quickly
replaced by air. All the cells, totally independent
from one another (closed cells) are encased in
the concrete, hence the name aerated concrete.
Raw materials
Only mineral matter:
- Pure white sand
- Lime
- Cement
- Aluminium powder
Once the lime/aluminium powder reaction has
finished, the concrete mixture has enough
consistency to be removed without losing
its shape.
The concrete mass, at the start of the hardening process,
is cut to the required dimensions with a steel wire.
BETONBLOC® SEDPA is then processed in an autoclave
at 180 C. During this process, mainly calcium hydrosilicates
are released, giving the product its final stability.
Following the autoclaving, of between 8 to 12 hours,
the concrete items have acquired their resistance, their final
properties, and are ready to be used.

Manufacturing reinforced products
A reinforced mattress composed of anti-rust
cold drawn steel bars is incorporated into the
liquid concrete mix when it is poured into the
moulds.
Texture
BETONBLOC® SEDPA, white mineral product, chemically
stable, is free from organic matter: it is therefore completely
rot-proof. The texture is formed by millions of miniscule
closed cells, encased in concrete.

ADVANCED FEATURES
• Mechanical strength
• Earthquake-proof
• Thermal insulation
• Thermal comfort
• Sound insulation
• Fire resistant
• Fixing
• Economical
• Environmentally friendly
• Mechanical strength
BETONBLOC® SEDPA has a mechanical strength 30%
greater than some traditional carcassing materials.
Its assets are guaranteed solidity, stability and long life.
• Earth-quake proof
BETONBLOC® SEDPA is ideal for building work carried out
in earthquake zones, due mainly to the lightness of the
materials and its thin cement layer installation system.
However, for a good installation, it is recommended to use
the same materials from the cellar to the loft for a
homogeneous construction, remembering to follow the
current regulations in force in earthquake zones.

• Thermal insulation
BETONBLOC® SEDPA provides your building with
exceptional thermal insulation, without the need for
any additional insulating material. It is energy-saving
thanks to its perfect insulation, allowing you to save money.
• Thermal comfort
The structure of BETONBLOC® SEDPA used for all
building work (doors, floors, roofs) allows you to
eliminate thermal bridges, thus guaranteeing you
exceptional comfort. In summer as in winter, the
inside temperature remains healthy and pleasant.
• Sound insulation
BETONBLOC® SEDPA meets the requirements of the
new sound regulations currently in force, giving perfect
sound insulation for both internal and external noises.
• Fire resistant
BETONBLOC® SEDPA: guaranteed fire safety.
Due to its natural mineral matter, it is non-combustible
and acts as a fire stop for between 1 and 6 hours
depending on its thickness.
It guarantees an exceptional protection against fire for
industrial buildings as well as houses. A1 classification.
• Tools
BETONBLOC® SEDPA's large range
of tools guarantees
an extremely easy installation,
whilst allowing highquality
precision and
finishing work (shaping,
installing, drilling, grooving).
11

ADVANCED FEATURES
• Economical
BETONBLOC® SEDPA allows you to make savings, particularly of
time, by reducing the duration of the building work thanks to its design.
Its sound and thermal insulation properties will allow you to cut
your energy consumption.
The durability of the SEDPA concrete block building system means
you will not have to carry out any renovation work (unlike other
building systems).
• Environmentally friendly
BETONBLOC® SEDPA is environmentally friendly.
It does not contain toxic materials or radioactive elements.
It is environmentally friendly, from its production through to its use
in construction work.
Thanks to its thermal non-conductivity, BETONBLOC® SEDPA saves
energy and does not pollute the atmosphere, unlike other building
materials.
Few raw materials are required for its manufacture, thus protecting
natural resources: it therefore protects the environment.
