bricks and blocks are alternative building materials to the
traditional burnt clay bricks and are substitutes to the
traditional burnt bricks used for construction.
- Fly ash is
mixed with lime & gypsum. Chemical accelerator may or may not be
added to it. This mix is moulded under pressure. Air / sun
drying may be done. Then this green brick is water cured.
technology adopted for making fly ash bricks is eco-friendly. It
does not require steaming or auto calving as the bricks are
cured by water only. Since the firing process is avoided,
there are no emissions and no effluent is discharged. On the
other hand, it solves the problem of fly ash disposal.
process of FaL-G bricks and blocks does not involve sintering
and thus completely eliminates the burning of fossil fuels as
required in the clay brick production, ultimately contributing
to the reduction of greenhouse gas emissions.
materials required for manufacturing of bricks are Flyash, lime
gypsum and sand(optional) .
manufacturing process s of bricks broadly consists of three
operations viz. mixing the ingredients ,pressing the mix in
machine and curing the bricks for stipulated period.
excellent engineering property and durability of fly ash brick
enlarges its scope for application in building construction and
development of infrastructure, construction of pavements, dams,
tanks, under water works, canal lining and irrigation work etc.
Construction provides the direct means for the development,
expansion, improvement and maintenance of human settlements is
particular and economic growth in general.
