Benefits:
-
Water absorption capacity is only 6
to 7% (in bricks15 to 20%)
-
Reduce the cost in
-
wall up to15 to 25% separately &
-
total construction cost up to 20%
Usage:
- Easy to
electrification and plumbing
- On account of
its regular, uniform and large size
- block laying &
plastering (if needed) are easier
- thickness of
plaster is 6mm instead of 12mm on brick wall
- Reduce
construction time & labor cost than conventional
system
- On account of
large size of concrete blocks, the number of
joints in a work are lesser and hence there is
saving of mortar (60%)
- On account of
good properties of concrete, the protective
covering is not mandatory for block work as is
necessary in case of brick work.
- Wall can be
painted directly if required
Stength:
-
Hollow block: ~ 5 Mpa
(specification, 4 to 7 Mpa)
-
Clay bricks: 17 MPa (Tested from
HBRI)
Scope:
-
This sector is potential in
Bangladesh that can replace the Conventional Clay
Bricks
-
Government has plan to stop brick
field in 2010
-
This should increase cement demand
substantially
