Cement and chemical additives which are among the biggest cost items in the price of concrete vary depending on the impurity (clay content) and quality of concrete aggregates. In quarries that produce aggregates for ready-mixed concrete plants, the quality (clay content and dirtiness) of the aggregate is generally determined by the blue methylene (MB) value and it is tried to be kept under quality control according to the MB value. In order to reduce concrete costs, while trying to keep the quality under control in the quarries producing aggregates for ready-mixed concrete plants, the mineable reserve, investment and production costs of the aggregate quarry are generally neglected. In this study, it is aimed to minimize the concrete costs and to ensure that the aggregate quarries are operated with the greatest profitability with the least loss of resources throughout the production life by developing a cutoff MB optimization algorithm in quarries producing aggregates for ready-mixed concrete plants. With the developed optimization algorithm, an application study was carried out by using the data of an aggregate quarry producing aggregate for the ready mixed concrete plant. In the application study, when the optimization is performed by considering the statistical distribution and economic parameters of the MB value of the aggregate quarry materials, the optimum limit MB value is found to be 3.00 and the profitability index increases from 11.1% to 44.9%. As a result of this study, it has been determined that quarry and crushing-screening plant can be used effectively without much loss of resources by taking into account not only the minimization of concrete costs, but also the optimum cutoff MB value.
