Název v původním jazyce
Electrical Conductivity of Cement Mortars and Pastes at Early Stages of Setting and Hardening
Popis výsledku v původním jazyce
In this work we present preliminary results of electrical conductivity measurements in cement pastes and mortars at a first stages of phase transition. Using a newly developed equipment, the dependence of electrical conductivity on temperature, resp. onvarious w/c ratios is determined both for cement pastes and mortars. It is shown that due to nucleation process the concentration of Ca2+ ions, resp. of OHhydroxyl groups is lowered within solidifying system resulting in decrease of total electrical conductivity.
