"Behavior of concrete mass during hydration - exothermic process with hardening of the concrete structure";
Talk: workshop "Training and Research Needs in the field of Heat technical properties of High Performance Concrete", Kosice, Slovakei (invited); 2007-10-29 - 2007-10-30.

Thermal technical properties and also physical properties of hardening concrete are changing during of hydration process. These changes are simultaneously accompanied by the changes of the thermal conductivity coefficient, heat capacity and strong exothermic process of hydration heat. Change of thermal technical properties and high heat generation is the cause of the volume changes in the concrete microstructure and the formed tensile stress. In the previous years this fact was neglected and massive reinforced concrete structures were designed and implemented without a regards to heat-technical balance. This resulted in changes in the concrete microstructure and the formed tensile stress caused formation of cracks.It is necessary to carry out heat technical calculations even in the case of structures which are not directly defined as massive but also towards structures which increased qualitative demands.
