Compozite cement; is a common term that describes slabs produced from
fiber-reinforced cement and is generally used all over the world. The
common feature of fibercement sheets is that they are produced with
organic or inorganic fibers, as reinforcing element, and cement, as
binding element. Compozite cement sheets are covered by EN 12476
Standard. Two different methods are used in the production of composite
cement sheets: Curing and Autoclave. According to the purpose of use, in
order to provide improvement the properties of fcomposite cement panels
such as heat insulation, electrical resistance, fire resistance etc. different
additives may be added to their composition during production of
panels.In recent years, composite cement sheets that are the most
preferred cladding material on exterior façades; have a different place
from other cladding materials in terms of both aesthetics and strength.
Composite cement panels can be used as both interior and exterior
cladding material. It protects the exterior façade from adverse weather
conditions and provides an aesthetic contribution to the façade as a
cladding or surface coating material.There are two types of cement-based
fiber cement sheets produced by pressing at high density; colour through
panels and surface coated panels.Colour-through fomposite cement
panels are produced by mixing the desired dye pigments into the dough
homogeneously during production. Production of surface coated
composite cement panels is carried out by processing colour or pattern
with artificial resin on high density pressed plate and by coating UV
protection filter on the surface. The density of composite cement sheets is
about 1300-1400 kg/m3. That is, approximately 10 kg load per square
meter.Composite cement sheets with an average thickness of 10 mm are
used in facade claddings.If the plaster is applied to the façade, instead of
composite cement façade cladding, approximately 30-40mm thick plaster
should be applied. The density of the plaster is 2000 kg / m3. Accordingly,
the composite cement façade cladding is lighter than the plaster. Two layers
of plaster are made also in the sheathing process which is made with the
purpose of thermal insulation only and ultimately, the load on the façade is
more than the composite cement cladding. In summary, an additional risk in
terms of earthquake is not added to buildings covered with composite cement
cladding. Production of surface coated composite cement panels is carried
out by processing colour or pattern with artificial resin on high density
pressed plate and by coating UV protection filter on the surface. The density
of composite cement sheets is about 1300-1400 kg/m3. That is,
approximately 10 kg load per square meter.Composite cement boards with
an average thickness of 10 mm are used in facade claddings.If the plaster is
applied to the façade, instead of composite cement façade cladding,
approximately 30-40mm thick plaster should be applied. The density of the
plaster is 2000 kg / m3. Accordingly, the composite cement façade cladding
is lighter than the plaster. Two layers of plaster are made also in the
sheathing process which is made with the purpose of thermal insulation only
and ultimately, the load on the façade is more than the composite cement
cladding. In summary, an additional risk in terms of earthquake is not added
to buildings covered with composite cement cladding. Composite cement
boards can be safely used in all kinds of buildings and building types,
especially in public housing, public buildings, commercial buildings, factories
and villa projects. Skyscrapers / Universities / Dormitory buildings / Hospitals
/ Metro and Tunnels / Shopping centers / Residential restorations /
Businesses and villas / Prefabricated buildings are some of them.
WHAT IS COMPOSITE CEMENT?
WHY COMPOSITE CEMENT?
Composite cement boards, which are preferred due to their technical
advantages and decorative appearance, prevent the building façade from
being deformed and damaged from external factors when used on the
exterior façade.They have positive effects on heat and sound insulation
with the effect of the fixing method. Being resistant to fire and flaming and
being suitable for all season conditions are some of the technical
advantages of the boards. Being anti bacterial and waterproof, being not
containing and producing any substance harmful, to human health and the
environment, no discoloration due to sun and heat, no fading and no
swelling on the surfaces of the panels are the main reasons why panels
are preferred.Composite cement boards, which are a human and
environmentally friendly material, do not have any gas emissions to the
environment in time or due to atmospheric conditions or during a possible
fire. Maintenance free, composite cement boards have very long life; there
is no predicted life expectancy for both cement and silica, their lifetime is
theoretically infinite when appropriate protection measures are
taken.Composite cement boards are extremely durable because they are
produced under high temperature and pressure and show high resistance
against impact. It is very resistant to atmospheric conditions depending on
raw materials in its structure and production procedure.
Composite cement panels are not affected by ultraviolet rays.It is also
highly resistant to animal waste and chemicals (especially alkalis), except
for descalers.Other features that differentiate composite cement façade
cladding from other façade cladding materials; composite cement boards
are not affected by water and sea water.
They're waterproof. Water absorption rate of the panels is lower than that
of reinforced concrete buildings. The panels do not swell in water, do not
mold and are not affected by moisture.They can be used safely in humid
climates, the volumetric changes in water are very low (maximum 0.5 mm /
m when left in water for 24 hours).
Since they are not affected by sea water moisture, they can be used safely
on the exterior walls of buildings in coastal areas.Composite cement boards,
although not an isolation material alone, has extremely good heat
values.When the panels are used with materials with high insulation value,
very good heat and sound insulation can be obtained.Since the panels
adhere very well to various insulation materials (polystyrene foam, etc.),
they can also be used as sandwich panels for various purposes.Composite
cement boards are compared with equivalent materials; the coefficients of
expansion are very low, with the correct joint application, no problems are
seen in the joints of the panels.They can be easily processed with suitable
hand tools, they are quick and easy to assemble and disassemble.They
saves time and labor since they remove fine plaster workmanship in
buildings. Since composite cement is a breathable material it allows the
building to breathe.Composite cement boards are lightweight and easily
transportable (weight of an 8mm thick sheet is approximately 11 kg/m2
depending on the humidity of the environment). They are frost resistant and
can be used safely even in the coldest climates.Composite cement panels
can be painted with acrylic exterior paint and plastic interior paint due to the
cement in their structures.The panels are odorless, insect free and do not
rot.
