ULTRA BRICKS
ULTRA
BRICKS are Cement Concrete
Bricks (closed cavity), manufactured in accordance with IS IS 2185 (Part1-1979, re-approved in 2003). As it is load bearing it is substitute for the conventional
bricks (clay).
ULTRA BRICKS are in different sizes and grades as mentioned below: |
| The
different grades
are, |
| ULTRA
A - 50 kg / cm2 |
| ULTRA
B - 35 kg /
cm2 |
| ULTRA
C - 20 kg / cm2 |

What
is the difference between
Conventional Cement Concrete Hollow
Bricks and ULTRA BRICKS?
There
are lot of differences ... |
|
ULTRA BRICKS
Ingredients
- 12
mm metal, 6mm
metal, M-sand &
cement
- Designed
mix for minimum
voids &
maximum density, as
such the bricks
will take more
loads.
Shape
- Designed
in such a way that
the cross walls of
successive layers
will come just one
above the other so
that the web will
also take the
load. There for it
will have more
area per brick to
take the vertical
load.
- As there is no
notch vertical
joints can be
filled properly.
- Vertical
reinforcement can
be provided to
make the wall
ductile as
envisaged in IS
4326 :1993
|
Are
there advantages over
conventional brick (clay)
work?
Yes,
there are: |
|
|
Conventional
Hollow Blocks
Ingredients
- Generally
6 mm metal &
crusher dust.
- Not
Designed mixed, as
such voids are
more and not
suitable for load
baring walls.
Shape
- Cross
walls (web) will
not take the load
(only the long
walls will take
the load) hence
less area per
brick to take the
vertical load. As
there is notch
vertical joints
has to be filled
from the top, and
filling will be
laborious and will
not be proper.
- Vertical
reinforcement
cannot be
provided.
|
 |
|
|
- Five
sizes (Ultra 22, 20, 19, 16 and
Ultra 10) and three grades (A-
50 kg / cm2, B - 35 kg / cm2, C-
20 kg / cm2) to choose for
different types of works.
- Vertical
reinforcement can be provided as
envisaged in IS 2185 (Part1-1979, re-approved in 2003)
to
make the wall ductile and EARTH
QUAKE RESISTANT with out
additional work expense and
expert labor force.
- As
joints (both horizontal &
vertical) are less compared to
the conventional bricks, ULTRA
BRICK work will take more loads
and the consumption of cement
and sand are also low.
- As
the unit weight is less compared
to the conventional brick work,
the structural design will be
cheap.
- About
6 % more carpet area will get
for the same plinth area.
- Wiring
can be done with out chasing the
brick work.
- Inside
room temperature will be less by
about 4 to 5 degree C.
- Brick
sizes are suitable for adopting
Vasthu Sasthra.
