Fly
Ash Bricks Introduction
Fly ash blocks are a building material, specifically masonry units, containing
class C or class F fly ash and water. Compressed at 28 MPa and cured for 24
hours in a 66 °C steam bath, then toughened with an air entrainment agent, the
bricks last for more than 100 freeze-thaw cycles.
In other

The Best Raw Material Ratio for Fly Ash Bricks
Supertech Creations going to describe what is the best raw material mixing
ratio for produce good quality of Fly Ash bricks.
The ratio
of raw material for Fly Ash bricks is depends on the process and the
ingredients.
1. Mixing Proportion
for Fly Ash Bricks
·
Fly ash – 57 to 65%
·
River Sand or Stone dust –
18 to 27%
·
Hydrated Lime – 9 to 12
%Gypsum – 5%
This is
the widely practiced mix proportion to make quality fly ash bricks. Hydrated
lime is easily available and this is the most common method followed by many
successful brick makers.
2.
Mix Proportion For
Bricks Manufacturing Using
·
Fly Ash (major part) – 55
to 60%
·
River Sand or Stone dust –
20 to 25%
·
Sludge Lime –15 to 22%
·
Gypsum – 5%
Sludge lime is a waste material and hence it costs less
than hydrated lime. Sludge lime is normally wet and has lumps; however, it can
be used to make quality fly ash bricks.
3.Mix Proportion for Fly Ash Bricks Manufacturing Using Cement Instead of Gypsum and Lime
·
Fly Ash – 50 to 60%
·
River Sand or Stone Dust –
30 to 40%
·
Cement – 8 to 12%
In this Mix design, cement is used instead of gypsum and
lime.
Cement is
more expensive than Gypsum and Lime; hence this formula is useful only during
non-availability of gypsum and lime.
