Abstract

A method and an apparatus for characterizing composite materials (2) is disclosed. According to invention acoustic waves are transmitted through a composite material (2) and an oscillogram of the acoustic signal is measured and analyzed in order to determine structural and/or mechanical parameters of the composite material (2). The invention is particularly useful to examine concrete (2), mortar or gypsum and in particular Roller Compacted Concrete (RCC). In preferred embodiments an acoustic energy E and optionally other acoustic variables, such as frequency, amplitude, intensity or signal attenuation of the acoustic wave are derived from the oscillogram and are correlated to elasticity, density, strength, internal tension, imperfections, discontinuities, phase changes (gaseous, liquid, solid) and/or setting time of the concrete (2). The invention can be used to monitor the setting and hardening process of concretes (2) such as RCC.
