Clay Bricks & Tiles

• A fully indigenous brick making machine has been developed which brings in semi mechanisation within the reach of a common brick manufacturer. Within the reach of a common brick manufacturer. With the use of this extrusion machine, a small scale unit can produce 2,500 wire cut bricks of 225* 112.5* 75 mm size in an hr. It can also produce other forms of clay units useful for flooring and roofing purpose. An automatic reel type cutter and a high draught brick kiln is used in conjunction with this machine.
• Redmud improves the quality of bricks made from inferior soils deficient in clay content. Red mud compositions give bricks of pale brown, orange or golden yellowcolour depending upon composition of raw material and firing temperature. They have therefore good architectural value as facing bricks. The presence of 4-5 % of alkali in redmud provides a fluxing action resulting into good plasticity and a better bond in the bricks. These can be used for all types of construction.
• Although the basic principles of manufacture are fairly uniform, individual manufacturing plants tailor their production to fit their particular raw materials and operation. Essentially, brick are produced by mixing ground clay with water, forming the clay into the desired shape, and drying and firing. In ancient times, all molding was performed by hand. The manufacturing process has six general phases: 1) mining and storage of raw materials, 2) preparing raw materials, 3) forming the brick, 4) drying, 5) firing and cooling and 6) de-hacking and storing finished products.
• The demand for bricks is expected to be about 100 billion per year by the turn of the century. Even if only 50% of the estimated demand of 100 billion bricks per year, is met from fly ash for productive use saving alternate resources, and reducing environmental hazard to that extent. In addition, it would save thousands of hectares of land from being used as ponding area.
