One of the directions intensively investigated in the field of milling is high-energy milling (HEM). One type of HEM is high-speed grinding in high-speed disintegrators. This type of mill is particularly suitable for the grinding and activation of fi

The decomposition of limestone during the firing process is mainly based on the decarbonation of CaCO3. In the case of crystalline limestone, it is the decomposition of calcite crystals. In this study, different limestone properties on the course of

Lime reactivity is the most used identification parameter for lime quality. The reaction may vary in its rate and maximum reached temperature. In this study, the influence of the properties of limestone on the course of the reaction is studied. The s

Limestone is used in the flue gas desulphurization process due to its ability to form sulfur compounds. Different qualities of limestone absorbents can be used in the process and it is therefore important to measure the reactivity of these materials.

In the current construction industry, great importance is given to the usage of thermally insulating building materials. One of the many such materials can be a cement foam or foam concrete, a mixture of cement mortar and technical foam. This materia

Thermal treatment of materials involves phase transformations. In the case of conventional laboratory furnace or in an industrial process, the samples are analysed after cooling. In this way, these phases can be monitored. A possible solution is non-

The replacement of primary raw materials in cement production is a relevant topic today. One potentially usable raw material is recycled glass. The disadvantage of glass is its tendency towards aggregation. Due to this phenomenon fine glass incement

Important part of research of properties of limestones during firing process is knowledge of all characteristics of used samples. One of the many characteristic is the residual CO 2 after firing. This parameter can be determined by various methods, h

Depending on nature of calcination process, we expect to get lime with specific features, for example fast or slow reactivity, certain grain size or lime that provides hydrated lime with high specific surface area. However, reality is often completel
