Granitic rocks are sometimes ground for different purposes. Predicting the mean particle size (d50) is useful for planning and cost estimation of purposes. In order to investigate the possibility of predicting the d50 of ground rock from the physico-mechanical rock properties, six different granites were tested in the laboratory. First, the d50 values were correlated with the corresponding physico-mechanical properties. The simple regression analysis showed that there were no good correlations between the d50 and the physico-mechanical properties. Then, the multiple regression analysis was carried out and strong prediction equations were developed. It was also shown that the dominant parameter in grinding was the abrasive mineral content of rock. It is concluded that the d50 of granites can be predicted from the derived multiple regression equations especially for preliminary investigations. The developed estimation equations including index test values are especially useful since they are easy to use.

Bottom ash is an industrial waste produced by the combustion of coal in industrial plants. These wastes are still under discussion as an environmental issue because of the very restricted field of use. Therefore, numerous studies have been getting performed to reduce the amount of wastes and to reuse the current residues produced by the coal-powered plants. It is a known fact that, there are hopeful developments on usability of industrial wastes in construction technology. In this study, use of bottom ash-obtained at Bor Sugar Factory as by-product, Niğde-Turkey, which contains unburned carbon by about 20% in production of brick as an additive was investigated. The results showed that bottom ash could be used as an additive in producing bricks and this process was found to be a good alternative for recycling such wastes.
