Research on clay raw materials for manufacturing of clinker bricks

Abstract

We developed a basic approach for determining the possibility of using clay raw materials for the manufacturing of ceramic clinker bricks. A complex of properties is given that allow establishing rational technological parameters of forming, drying and firing of ceramic products. Composite charges were prepared based on clays of different mineralogical types from the Druzhkiv, Siver and Ozeryan deposits (Ukraine). It was established that on the basis of experimental materials by means of plastic forming and firing at temperatures of 1100–11200C it is possible to obtain ceramic clinker bricks with a water absorption of 4–5% and a mechanical strength of 29.8–30.0 MPa, which meets the requirements for clinker bricks. The obtained characteristics of previously unexplored clay raw materials open the possibility of their wide application in the construction industry.
