Experimental study on hollow interlocking FaL-G bricks

Abstract

Thermal power industries produce a large amount of fly ash, a waste product. Lime is a material used in many companies in chemical processes and deposited as waste. A by-product of the fertiliser business is phosphogypsum. In our country the proper disposal of the industrial waste is a big issue. To find remedial measure for disposal of the industrial waste, in this study an attempt is made to check whether it is possible to create hollow interlocking bricks out of all these waste materials. The present study reveals that all these materials can be effectively used to produce an alternative to conventional burnt clay bricks. If such bricks are used in construction activities, it will help to check the land pollution which is there due to use of good agricultural clay for the manufacturing of bricks as well as avoid the air pollution due to burning of bricks. The bricks manufactured using fly ash, gypsum and lime (Fal-G) require air drying no burning is required hence avoid air pollution as well.
