ABSTRACT:
A method for the determination of the setting process in an inorganic aqueous binder system, in that the electrical conductivity is constantly measured in the binder system, in that the variation of the electrical conductivity is differentiated according to time, in that the variation of the first derivative of the conductivity is monitored, and in that the temperature in the binder system is continously measured and the temperature dependence of the electrical conductivity is eliminated by means of the measured temperature values.
