Abstract
There is disclosed a computer-implemented method for determining a density value of a fresh concrete sample using an acoustic probe assembly. The acoustic probe assembly has an acoustic path, an acoustic emitter configured to emit an acoustic signal along the acoustic path, and an acoustic receiver configured to receive the acoustic signal after propagation along the acoustic path. The acoustic probe assembly is configured and adapted to generate an electromagnetic signal indicative of a duration of time taken by the acoustic signal to travel from the acoustic emitter to the acoustic receiver across the fresh concrete sample. The method generally has a step of determining the duration of time based on the electromagnetic signal, a step of matching the duration to a density value using reference data, and a step of displaying the density value.
