BRICK MASTER
Bricks are manufactured out of red-mud, coal dust and salt, Good quality red mud or black cotton soil is best raw material for Brick manufacturing. Chunkhadi or Calcium-carbonate percentage should be bare minimum. Fine Carbonate dust does not create problem, but coaser grits above 1mm in size , tend to burst at kiln temperature, leading to breakages & weak bricks.
Mud
is mixed
with water, coal dust & salt. Salt is added to neutratise calcium
carbonate grits (chun khadi) and
is found to redden the bricks after firing. To this water is added and
allowed to soak
by ponding over night. Next
day it is kneaded till fine consistency uniform & workable paste is
obtained. If the kneading is insufficient brekages occur.
This
doughty material
is now filled into metal
moulds & tamped, it is demoulded & placed to dry in sun for 6-7 days,
where after it is placed in the klin for firing.
In
case of
open klins
, the bricks are stacked & every 3/4th layer is
spread with coal dust & salt. The
klins are
open & heat to bricks can be effected by strong winds & rain,
& seasonal temperature changes.
It is imperative that
adequate time & heat be
given to bricks for it to develop high
strength. If
the bricks
are fired
in fabricated
kilns , adverse
effects of wind temperature &
rain are
nullified. Brick
Master is
specifically developed for manufacture of bricks from conventional mud
& open kilns & fabricated kilns.
Use
of Brick Master gives following advantages:
1)
Increase tolerance limits for Calcium Carbonate
grits (chun khadi). Brick Master dissolves chun khadi
& hence reduces breakages in bricks due to presence of chun khadi.The
over night soaking
& subsequent
kneading is
to ensure
that Calcium
Carbonate grits are broken down
, & mud
is completely
wetted with
Brick Master
the wetting
of mud is complete. The
kneading operation
is easy , smooth, uniform
consistency paste is easily obtained, Since the mud is soft
& easy to work with Brick Master. Brick finish is improved.
2)
Since
the mud
is soft
due to Brick
Master , tamping into moulds is easier & fine- clean surface finish
greens are obtained.
3)
When
the bricks
are moulded
& allowed
to dry
to develop strength
in sun. Due
to Brick Master better-faster strength is obtained. The breakages is
eliminated.
4)
After
the bricks
are placed
in kiln
& fired ,
faster strength
is developed, the effect of chunkhadi
is minimised.
Whilst lifting
bricks from
kiln &
loading no
breakages are
observed if Brick Master is used.
5)
Due to Brick
Master the brick colour is red & firm high strength bricks are assured.
It
is observed that in 1,00,000 bricks
kiln , about 20,000
to 25,000
bricks can
break. With Brick Master this breakages is eliminated.
It
is recommended
that initial few trials
should be taken without changing coal, dust content. After
few trials
Coal dust
may be
reduced upto
5% - 10% maximum.
However this reduction must be
done carefully. Keeping in
mind climatic conditions & temperature drops, winds, etc., due to seasonal
variations.
METHOD OF USE:
Prepare
mixture for 1000-1200 bricks , using usual quantity of mud, coal dust, salt,
water. Add 1 ltr Brick Master to 20 ltrs of water, mix well & spread this
over the mud-mix. Mix well. Allow it to stand overnight & knead as usual. No
other change in procedure.
Coal
dust content
in bricks
can be reduced, however this reduction must be attemped after few trials
only.
