 Wood Substitute

Industrial wastes such as redmud, flyash, jarosite, marble slurry dust, copper tailings, and natural fibres like sisal and jute have been used as fillers for developing a variety of polymer composites. The materials have been subjected to a  characterization  such as resistance to weathering and fire, mechanical, chemical, wear etc.  A comparison of features shows higher strength, greater resistance to corrosion and weathering for the developed materials than that of the conventional ones (wood). They are also insensitive to attack by termite, rodent, rot etc unlike wood. Display of their self extinguishing nature helps to reduce the severity of damage to the residents and buildings in the event of fire hazards. Also, their less maintenance and basic costs than wood make them further attractive. Products like door shutters, roofing sheets, panels etc. for building applications, as well as furniture. etc.  TThe developed door shutters were thoroughly tested by the Central Public Works Department (CPWD), Bharat Heavy Electricals Limited (BHEL) and Central Building Research Institute (CBRI) and finally approved by CPWD for public use
