Processing and utilization of industrial waste and the development of new building materials is being given the top priority in the program of building research all over the world. This is important for achieving maximum disposal of wastes and conservation of scarce resources and materials. The non conventional bricks produced were about 29% lighter than conventional clay bricks. The non conventional bricks manufactured possessed compressive strength higher than clay bricks. This exceeds the best of load carrying clay bricks available and is several times better than acceptable commercially available common clay bricks. Other important characteristics of the non conventional bricks have been evaluated too. The values of these characteristics for non conventional bricks are excellent and have exceeded those pertaining to clay bricks. Moreover, non conventional bricks have been produced with a naturally occurring reddish colour similar to that of normal clay bricks. The new bricks and process have been patented. This paper presents the results of testing and the advantages gained by this type of bricks over conventional clay bricks. In this study, the effects of nonconventional material on the properties of bricks are studied and the behaviour of nonconventional bricks is compared with conventional burnt clay bricks. Generally bricks are made by top fertile agricultural soil but by using nonconventional material, 26 % of top fertile agricultural soil is saved.The various properties of nonconventional bricks like absorption, hardness, efflorescence, soundness, shape and size, crushing strength and basic compressive strength of the prism using different mortar mixes normally 1 : 3, 1 : 4 and 1 : 5 cement-sand mortar were studied.
