Sustainable production of cement and quicklime: Thermochemical raw materials properties

PhD project Cement and quicklime are used in a variety of industrial applications: steel and paper production, glass manufacturing, housing construction. Limestone is the main raw material in the production of quicklime and cement. To ensure high quicklime and cement quality, more knowledge is needed on the thermochemical properties of the limestone.

Project description

The project focuses on the thermochemical properties of raw materials limestone and dolomite for cement and quicklime production. During the calcination (heating) process in a kiln (industrial furnace), limestone (CaCo3) under high temperature decomposes into quicklime (CaO) and carbon dioxide (CO2). The project aims to increase the quality of the final product and to reduce the environmental impact, throughout the investigation of the thermal behavior of limestone.

The project involves developing and evaluating knowledge concerning currently used methods for the characterization of raw materials. The first stage of the project focuses on investigating the thermal decrepitation of limestone. The project is conducted within the Center for Sustainable Production of Cement and Quicklime.
