Building Brick Dealers in Kalighat, Kolkata

These bricks are manufactured by the sawdust process using selected grades of china clay and kyanite for hot face as well as back up applications. Particularly notable is the HFK brick, which is one of the most economical insulations in its classification temperature. Rajhans also manufactures high CCS insulation tiles, RHR HSI for glass melter bottom and can supply the same in any size. This range of bricks has been entirely developed through indigenous research and is formed by the vibro-casting method. Vibro-casting ensures extremely low thermal conductivity and proportionately high strength. These bricks are engineered for cold face as well as hot face applications and can withstand temperatures of upto 1500°C. Tailor made solutions for kilns and furnaces based on vibro-cast bricks can be forwarded with cost benefit analysis in terms of energy savings.High Alumina insulationsThis range of insulation bricks have alumina content extending upto 95% alumina and are mostly use for applications starting from 1500°C.These products are distinguished by their pure chemistry, high hot strength and excellent volume stability in service. Especially notable are bubble alumina based bricks.

Over the years, as the construction industry evolved, there grew a need for an innovative solution that would replace traditional building inputs like clay bricks & also save cost and time. Fly-Ash bricks represents one such break-through innovation that has totally changed the face of modern construction. The product conforms to specifications for Concrete Masonry Units as laid out in India Standards IS: 12894: 2002. And to top it all, it is a Green and Environment-friendly product. These bricks are not affected by environmental conditions and remainstatic thus ensuring longer life of the building. Pulverized fuel ash commonly known as fly-ash is a useful by-product from thermal power stations using pulverized coal as fuel and has considerable pozzolonic activity. This national resource has been gainfully utilized for manufacture of pulverized fuel ash-lime bricks as a supplement to common burnt clay buildings bricks leading to conservation of natural resources and improvement in environment quality.
