METHOD AND APPARATUS FOR THE DETERMINATION OFKINETICS OF STRUCTURE FORMATION IN A BINDERAbstract of the DisclosureA method for the determination of kinetics of struc-ture formation in binders comprises applying a voltage toa product made of a binder and recording the electricalconductivity of the product during the process of itsstructure formation.An apparatus for the determination of kinetics ofstructure formation in binders comprises an a-c voltagegenerator connected through a coupling device to the pro-duct made of a binder for acting thereupon and to a devicefor recording the response of the product to this action.The coupling device comprises a pick-up for measuring theelectrical conductivity which is installed in the productand connected to the a-c voltage generator and, via aseries circuit including a differential inductive bridgecircuit, a voltage amplifier, and a phase detector, tothe device for recording the response of the product tothe action by the generator.
