Huge number of sand-workers is engaged in lifting and
carrying sand from the sand-lands emerged in river of
Durgapur, Netrokona district. These are the superior
grade sands containing both fine and coarse gravels
coming down from the hills of India. Researcher as President
of Sand-Workers felt that this high quality sand could
be used for making concrete bricks. Sand-based concrete
bricks will be environment friendly and less costly
than the conventional fire-burnt bricks. The present
research is aimed at (i) developing a technology for
making sand-based concrete bricks and (ii) developing
a prototype semi-automatic machine for making such bricks.
Cost of making such bricks should be less compared to
conventional bricks. The technology expected to be developed
should be standardised and recommended by the concerned
authorities. A group of scientists from BCSIR and experienced
civil engineers will do the job. The technology and
the machine expected to be developed will be used by
the sand-workers for their increased employment as well
as empowerment.
