Abstract
Presented are the results of the research on the impact of such factors as temperature conditions and cement phase composition on the effectiveness of hardening accelerators for concrete and other cement systems. The evaluation of the modifying elements effect has been performed by using the isothermal calorimetry method. This research revealed the selectivity of the admixtures impact when used together with different cement brands, as well as the possibility of increase setting time for cement systems in lower temperature conditions with the addition of Lithium carbonate based accelerator.
