Reusing and Recycling of Granite Slurry in Construction Industry

The waste generated in the stone processing industry is directly related to the production and processing of various types of stones that have drastically increased every year. Marble industry brings out the amount of waste that has grown nearly three times in last ten years. The processing and polishing waste alone is 20% from mined out reserves. Only insignificant quantities have been utilized, and the rest has been dumped unscrupulously resulting in environmental problems and health issues. The results of the studies, on characteristics of waste generated from stone refrain many factories and reutilize the desolation, for making brick in combination with clay and preparing concrete with replacement of sand/cement has been conferred. Field studies assessed distinctive of waste generated in stone refrain manufactories, the impact of current disposal practices and waste recycling potential. Both physical and chemical characteristics of waste are compared with sand and cement. The environmental concern because of the waste disposal included on ambient air quality was pinpointed at disposal sites, respectively. The results reveal that the waste can be used to replace about 60% of sand and 10% of cement in concrete. Similarly, the waste can replace 40% of clay in clay bricks without compromising the conventional compressive strength.
