<p>The main intention of the present invention is the manufacture of brick from waste material of steel industry, fly ash, Brahmaputra river sand, and cement as binder. Lime mud, a waste material produced from paper industry is also used to replace the partial quantity of cement to make it more economical. This invention will help to reduce the disposal problem, environmental effects of this waste and manufacture a new building material. As mentioned, the materials used for brick making in this study are steel sludge, the waste of steel industry, flyash, Brahmaputra sand, lime mud, the waste of paper industry and cement. The characterization of materials was done on the basis of its chemical and geotechnical properties. Then the experiments were conducted on hand moulded bricks of above mix in various proportions to determine the optimum mix. The moulded bricks were 'allowed to dry for two days and protected from direct sun light. .Since cement was used in all the bricks, curing was done using moist jute bags for 28 days. All bricks were tested after 28 days for compressive strength and water absorption as per the provisions of IS: 3495 (Part 1 & 2)-1992, respectively.</p> |
