air pollution. There are no
thermal bridges, gaps for
things like studs where Rvalues drop, as there are in
standard construction. AAC is
easily routed for utilities
although electricians and
plumbers may not carry
routers with them or be used to
that technique. There have
been natural disasters where
AAC structures are the only
surviving buildings. Insurance
costs are lower. They are
popular in hotel buildings
because
of
their
soundproofing capability. All
building
waste
can
be
reprocessed.
First advantage is the blocks
are very uniform in shape and
are normally equal to six to ten
numbers of normal modular
brick of 4x4x8 inches. This
translated into uniformity in
brickwork, in both inside and
outside faces of wall. Plus the
added advantage of fast
masonry. One can achieve up
to five times fast progress with
ACC/
CLC
blocks
in
comparison to normal bricks.
The uniform shape requires
very thin mortar layer between
blocks, the joinery mortar is as
all know is a fairly costly
material being 1:4 mix of
cement and sand. The even
surfaced wall also requires
very thin plaster on both sides
which is also a very cement
intensive material and thus lot
of cost saving is done. Many
builders
are
nowadays
preferring "Gypsum Plaster"
directly over blocks wall, thus
plaster, putty is done in a single
activity one needs to just get
on with painting and finish the
unit.
The long term benefit of using
AAC/ CLC blocks one obtains
is by virtue of its being very
good thermal insulator. If the
outside temperature is say 36
degrees then the normal brick
wall will maintain around 32
degrees in room, whereas the
AAC/ CLC made room will have
temperature around
27 degrees, the cooling heating cost is one of the
major cost component in
monthly
maintenance
expenses if any building.
Saving on cooling/ heating in
entire lifetime of building will
be tremendously beneficial.
In buildings adjoining to traffic
areas like shops/ offices in city
center where noise pollution is
huge, or in office blocks of
industries where sound is
unavoidable AAC/ CLC blocks
can cut the noise off very
efficiently.
Any construction engineer
knows what’s happens to
normal brick walls when
groves are cut in masonry for
electric
and
plumbing
conduits. The wall almost rips
off leaving lot of cracks behind.
The hand chiseling or machine
cutting destroys the bond
between the already weak clay
bricks, as a result after the
plaster is done many a times
cracks appear above conduit
lines. The scene with AAC/ CLC
blocks is entirely different. The
blocks get cut very easily and
the joinery does not gets
disturbed at all.
Normal burnt clay bricks are
very disastrous to environment
not only the fertile top soil is
depleted but lot of carbon
mono oxide is released in
environment.
The
brick
industry is told to be the third
most coal consuming industry
after power and steel. The
Supreme Court has given
directives for phasing out of
burnt clay bricks.
So finally it’s just matter of
understanding and estimating
the benefits that AAC/ CLC
blocks offer. I am sure the
blocks will rule the world in
coming years.
