Studies of Utilization of Technogenic Raw Materials in the Synthesis of Cement Clinker from It and Further Production of Portland Cement

Four series of experiments were carried out to study the possibility replacing clay and an iron-containing component with tefritobasalt lead slag as part initial charge for Portland cement. The at atmospheric pressure a temperature 1350 °C. It was shown that replacement in cement industry will decrease by 100 °C technological scheme production reduction energy consumption, since theoretical specific consumption raw materials is 1.481 t/t clinker, which approximately 70 kg lower than traditional mixtures. content non-traditional components total 24.69%. In addition, tefritobasalts improved clinker formation processes, contributed firing temperature, intensified process. A small amount (5.06%) introduced into mixture changed structure process mineral while also improving roasting reducing anthropogenic impact on environment through disposal man-made waste. strength experimental composite cements tested after 7 28 days samples measuring 2 × cm. physicomechanical characteristics studied.
