An Experimental Study on Properties of Burnt Clay Bricks using Industrial Waste

There is over million tons of industrial wastes are being produced by mining industrial process per annual in India. The problem is to dispose these waste materials which are arising from continuous technological and industrial development. If some of these waste materials produced by industrial processes are found suitable and utilized in construction field, then the disposal of such waste materials can be achieved and thereby cost of construction can also be cut down. Kaolin waste (china clay waste) is one of such materials which is being generated by industries abundantly. Since kaolin gains strength on heating, an attempt is made in this investigation to utilize the kaolin waste in burnt clay bricks and results are studied. In the present work, burnt clay bricks are prepared with kaolin waste as a replacement of traditional clay in different proportions i.e. 5%, 10%, 15%, 20% and 25%. These bricks are tested for its basic properties and the results are compared with conventional burnt clay bricks. Masonry compressive strength test and flexural strength tests had been conducted on the masonry samples of optimum percentage. Finally it is concluded that industrial waste replaced burnt clay bricks can be successfully used in construction field since it has achieved more strength than traditional clay bricks and hence in turn disposal of some industrial waste found suitable way of utilization.
