Title:
METHOD FOR CHECKING THE CONSISTENCY OF A SUPPLIED CONCRETE OR A SUPPLIED CHARGE OF A CONCRETE
Document Type and Number:
WIPO Patent Application WO/2019/129521
Kind Code:
A3
Abstract:
The invention relates to a method for checking the consistency of a supplied concrete (1) or supplied charge of a concrete (1) in relation to an ordered concrete (1) having a consistency of a defined formula, by means of a TDR measuring probe (3) wherein the TDR measuring probe (3) is mounted in such a way that it is in direct or indirect contact with the concrete (1) and determines, during the running time of high-frequency measurement signals which are guided along a conductive probe element (4) of the TDR measurement probe (3), the conductivity or humidity of the supplied concrete (1) or supplied charge of the concrete (1). Said method comprises the following method steps: the concrete (1) or the charge of the concrete (1) is filled in or poured into a formwork (2), actual measured values of the TDR measuring probe are detected over a predetermined time range, the detected actual measured values are compared to the corresponding stored desired measured values of the ordered concrete (1), a signal warning that the supplied concrete (1) or the charge of the supplied concrete (1) has a consistency different from the ordered concrete (1) is generated if the time plot of the recorded actual measured values of the supplied concrete or charge of the supplied concrete (1) is outside a predetermined tolerance to the time plot of the known desired measured values of the ordered concrete (1).
