UTILIZATION OF MARBLE AND GRANITE WASTES IN BRICK PRODUCTS
Marble and granite sawing powder wastes is one of the major worldwide environmental problems. As a consequence of environmental and financial considerations, there is a growing demand for wastes to be re-used or recycled. Therefore, this work intends to discuss the possibilities of using marble and granite sawing wastes as alternative raw materials in the production of bricks. Samples of marble and granite wastes were collected from companies located in Madurai District. Clay mixture and fired industrial bricks were collected from a brick chamber located in Ramanathapuram District, Tamilnadu, India. Results obtained through chemical and mineralogical analysis (XRF and XRD), Liquid and plasticity limit and plasticity index, particle size analysis compressive strength, flexural rupture strength, water absorption, apparent porosity, apparent density and Bulk density, show that marble and granite sawing wastes can be added to the Ramanathapuram clay mixture upto 50 wt.% with no detrimental effect on the properties of the sintered brick products.
