FLY ASH BRICKS (CAP: 6000 NOS. PER DAY)

[EIRI/EDPR/4641] J.C.: 2858XL

Bricks may be made from a  no. of  different  kinds  of material,  but  they  must usually possess  (can  be  capable  of developing)   a certain amount of plasticity.  fly ash is one  of them.   Fly-ash is an industrial waste of thermal power  stations using  pulverised coal.  it is finely divided residue,  resulting from  the combustion of pulverised coal in the boiler,  which  is transported by the flue gases and subsequently collected by means of electrical or mechanical precipitators.

There are about 40 major thermal power plants in India which produces about 15 million tones of fly ash every year. Such enormous quantities  need  huge  dumping  grounds,  and   create pollution problems.

Fly ash being a puzzolanie material forms cementations products in conjunction with time and thus find  use  in  civil Engineering  Works.  In advanced countries fly ash has been  used in  variety of product during the last 2-3 decades.   Whereas  in this  country  a  very limited use of fly ash has  been  made  in hydraulic structures.  However, very little has been done on  the diversified  use of lips fly ash viz. in road  construction  soil slabbing precast block etc.

Even though research and development and suprimental construction has shown that fly-ash can be used with considerable advantages in building construction, the construction industry has still not taken to the use of fly ash to any large extent. The reasons asisigned for this may be.
