Sand Lime brick introduction

Sand lime bricks are manufactured by mixing sand, fly ash and lime in desired
proportion that may be followed by chemical accelerator during wet mixing. This mixture
is moulded under pressure. 
bricks. These bricks are suitable for use in masonry just like common
burnt clay bricks.

These bricks have the following advantages over the clay bricks:

1. Possess adequate crushing strength as a load-bearing member.

2. Have cement colour in appearance, are uniform in shape and smooth in finish

and require no plastering for building work.

3. They are lighter in weight than ordinary clay bricks.

Production Procedure of Sand Lime Bricks: 
 The process of manufacture of sand lime bricks involves the preparation of the
raw material viz., the sand and the quick lime, mixing them in the right proportion with
specified quality of water and allowing the mixture to react for a specified period. The
reacted material is once again taken and the moisture content suitably readjusted and
thoroughly missed again before it is passed on to the press hopper. This properly
prepared mixture is compressed under high hydraulic pressure to form the required size
of bricks/ blocks. These green bricks are autoclaved for a specified time at specified
temperature and pressure to harden the green bricks. This process of hardening gives
the required strength to the green brick. After this process of hardening, the brick is
ready for use immediately. If coloured bricks are to be manufactured suitable pigments
will be added at the time of remixing after reaction
