Abstract
Considerable amounts of wastes are generated as a result of the production and processingoperations in the natural stone sector. These wastes cause some environmental problems(topography change, surface/underground water pollution, air/visual pollution and so on). In thisstudy, potential use of the granite wastes (coarse and fine size) as abrasive in natural stone cuttingwith abrasive waterjet (AWJ) are investigated. The limestone samples used in the tests are cutlongitudinally. The cutting parameters are kept constant during the tests and the cutting depth isconsidered for assessing the cutting performance. The study results show that granite wastesmeet the requirements as abrasive in terms of reaction with water, hardness, toughness andshape. Besides, it is determined that a great majority (96% of waste slurry) of the fine materialsderived from the waste sludge doesn’t have required size for natural stone cutting with the AWJ.Additionally, it is concluded that materials obtained from the coarse granite wastes by crushing,grinding and sieving could be used as abrasive.
