COMPARISION OF FLYASH AND CLAY BRICK AVAILABLE IN PRAYAGRAJ MARKET

Abstract

In today’s world development of new building materials and Processing & utilization of industrial waste is given the high priority in the construction of buildings. Its important for achieving maximum disposal of wastes and conservation of renewable resources. The bricks produced were about 29% lighter than clay bricks. The compressive strength of bricks manufactured from fly ash possessed higher than 20 MPa. This exceeds the load carrying capacity of clay bricks available by more than 25% and is several times better than acceptable than commercially available common clay bricks. Other important characteristics of the fly ash bricks have been evaluated in the thesis. The values of these characteristics of fly ash bricks are good and have exceeded to those pertaining to clay bricks. The new bricks and process have been studied. This dissertation studies the results of testing and the advantages gained by this type of fly ash bricks over conventional clay bricks. In the present scenerio, the effects of fly ash on the properties of bricks are studied and the behaviour of fly ash bricks is compared with conventional clay bricks. The various properties of fly ash bricks with conventional clay bricks were tested. The properties studied were water absorption, hardness, efflorescence, soundness, shape and size, crushing strength and basic compressive strength.
