Invetion reffers to liquid accelerator for setting and hardening of Portland cement systems, which is alkali low or alkali free and chloride free. The liquid accelerator exhibits very fast setting of cement systems and fast compressive strenght gain and high final compressive strenght. The liquid accelerator is charactarized by simple synthesis.

Invetion reffers to liquid accelerator for setting and hardening of Portland cement systems based on cryolite bath, which is alkali low or alkali free and chloride free. The liquid accelerator exhibits very fast setting of cement systems and fast compressive strenght gain and high final compressive strenght. The liquid accelerator is charactarized by simple synthesis and low price of the final product.

Compressive strength evolution of concrete and mortar depends on cement hydration rate. The most important parameters that influence the hydration rate are temperature, type of cement, water - cement ratio, chemical and mineral admixtures, and in case of polycarboxylates an architecture of polymer. Hydration rate of several paste and mortars was measured by isothermal calorimeter. Experimental results, isothermal heat flux and hydration heat, were correlated by compressive strength of mortar. Influences of polymer architecture and reaction temperature on cement hydration were studied as well.
