Fly ash Bricks | An alternative Building Material
Fly ash bricks are masonry units that are used in the construction of buildings. They are considered to be a part of good and affordable building materials. They contain Class C fly ash and water.
Fly ash bricks are made by compressing Class C fly ash and water at 4000psi and then curing is carried on for 24 hours at a temperature of 66 degrees Celsius steam bath. Air entrainment agent is used to toughen the bricks.
Fly ash Bricks
Since the concentration of calcium oxide is very high in class C fly ash, the brick is described as self cementing.
It is considered to be a good alternative to traditional mud bricks since the method of manufacture of fly ash is energy efficient that is it helps save energy, brings about reduction of mercury pollution and plus it is cost effective.
Raw materials used for the manufacture of Fly ash Bricks:
- Fly ash – which is the primary ingredient
- Sand or Stone dust – as fine aggregate
- Lime – source of calcium carbonate which results in the bricks being called “Self-cementing bricks”.
- Gypsum – to enhance the fineness of the shape of the bricks
- Cement – to increase bonding and strength

Bonds in Brickwork | Building Construction
In our previous articles, we discussed “what is a bond?” and “Rules for good Bonding”. Let us start our further discussion on types of bonds.
Different types of bonds are:
- Stretcher bond
- Header bond
- Facing bond
- English bond
- Flemish bond
- Dutch bond
- English cross bond
- Brick on edge bond
- Raking bond
- Zigzag bond
- Garden wall bond
Now we will proceed with our in depth discussion on “Stretcher bond” and “Header bond”.
What is a Stretcher Bond?
As the name itself suggests, stretcher bond is formed by laying bricks horizontally as stretchers on the faces of walls. The length of the bricks is along the horizontal direction of the wall.

Stretcher bond is used when walls of half brick thickness are to be constructed. The average size of the brick is 9cmx9cmx18cm. If the wall of thickness 9cm is to be constructed, then stretcher bond can be used.
Various types of wall constructions are done using this type of bond.
- Sleeper walls
- Partition walls
- Division walls (internal dividers)
- Chimney stacks

Changing trends in the choice of Building materials
Nowadays, people are gaining more knowledge about eco-friendly lifestyle. They are realizing that eco-friendly materials are much better and safer as compared to the synthetic and energy intensive materials. Though use of synthetic materials give a very stylish and trendy look to the place, they are not eco-friendly. The trend is definitely away from the older classical looks, associated with bygone grandeur and towards more contemporary styling. Fabric is more textured and interesting, with graphics, florals and interesting weaves and patterns to the fore.
Fabric used as a material for covering the furniture
The palette is lighter and brighter than before, in keeping with the move away from the traditonal to the contemporary, also following what is seen as international, stylish and sophisticated. Instead of saying ‘the look has changed’, I would rather say the look and feel of traditional interiors has evolved. New design languages generated by new materials and new uses of existing materials have resulted in a truly matured genre of beautiful and amazing interiors.
