quality precast aer-
ity of 1500 Villas per year (300m2 average area per villa), and a total investment
of 100 Million Dirham.
With the most advanced PAC technology in the Middle East, BENA started produc-
tion in January 2009.
BENA is the first to introduce a load bearing system using PAC material; we design
and produce a complete building “Skeleton” using the highest quality concrete in
the construction industry. Our system is characterized by the speed in installation
and its cost-effectiveness.
We produce Reinforced Vertical PAC Panels or load-bearing PAC blocks for
walling along with PAC Slabs for flooring to continue an alternate Superstruc-
ture System that is one-third the weight of Conventional Concrete while provid-
ing superior sound, fire and thermal insulation.
This environmentally sustainable product has a very low embodied CO level and
creates energy efficient homes.
At BENA, we are more than simply suppliers of Precast Aerated Concrete
units. We are partner with our customers, our employees, and our investors,
providing high quality building structure, a stable and productive workplace,
and strong shareholder value. BENA recognizes that in order to survive and
grow in today›s challenging marketplace, true commitment in meeting cus-
tomer needs through communication, planning and continuous process im-
provement activities is the key.

2. 1.Mixing
Precast Aerated Concrete (PAC) is a
mixture of sand, cement, lime, gyp-
sum and water. The fine silica sand
is ground to a powder in a ball mill,
so all the ingredients have a similar
particle size. Computer controlled
density meters and mixing equipment
ensures the exact proportions are
used every time.
2.Casting
Mixing the raw materials will form
slurry which will be casted in a 6 me-
ter long steel mould.
3.Rising
The casted mould will be driven in to
the fermentation area for a period of
3-4 hours until the cake gets its initial
setting and pre-curing.

3. 4.Cutting
The cake is released from the
mould, ready to be sliced into
blocks and panels. Fine steel wires
are used to slice through the soft
concrete. Computer monitored
pneumatic tensioners keep the
wires tight and straight for the per-
fect cuts. All the side trimming and
waste off-cuts fall into the channel
below and are pumped back into
the mixing system for recycling.
5.Curing
To make the PAC strong and hard, it is fused under heat and pressure in steam
autoclaves. These 40 meter long pressure cylinders take 21 cakes at a time and
cook them at temperatures of up to 190 degrees Centigrade and pressures of 12
bars.
6.Packing
After a series of thorough inspections
and quality control, the PAC products
are now ready for dispatch.

7. Noise Resistant
• Sound insulation value of 7db (per sq. ft. of surface area)
greater than other materials of the same weight
Economical
• Fast installation – quicker customer payback
• No furring, insulation or drywall needed
• experienced four man team with crane
can install panels at 4-6 minutes per panel
Long Life
• Excellent for hot to very cold climates
• Approved for use in hurricane prone areas
Enveronment Friendly
• PAC is made from sand, lime, cement, water
and a rising agent
• Generates no pollutants/hazardous wastes
Breathable
• Air molecules allow transfer of moisture vapor from cook-
ing, washing and cothes drying.
• PAC walls allow the building to equalize pressure between
the outside and inside atmosphere.
