Fire
test
A brick which
is used for construction should not flammable in open flame, so this test was
carried out for the bricks. This test was carried out only for fibrous concrete
bricks not for padobe brick. Because padobe brick was already heated in kiln at
high temperature so, it won’t burn. The following are the steps involved in this test,
o
First, the brick was wiped with cloths and all
the foreign matters were removed.
o
Then the flammable sticks were fired. After
that, the bricks were held on the flame for five minutes.
o
After five minutes fixing was stopped and the
bricks were observed.
From
the above test, it was observed that the fibrous concrete bricks did not burn
with an open flame. They smoldered like charcoal. But these brick would be
reduced to ashes after burning several hours. If the interior plaster and
exterior stucco is provided on the fibrous concrete bricks, the bricks won’t
burn. The only weak point is inside the block, near electrical outlets,
switches and other places where wires gives through walls, into boxes etc.,.
Properly wired places never cause fire. If we apply the plaster without any
hole or leakage on the bricks, it won’t burn or smolder inside. Because there
will be lack of oxygen for burning
