Abstract
The invention relates to the determination of the dynamic elastic modulus of a material, such as a material comprising a mineral binder like cement, or gypsum, or the like, or a polymer, or ceramic, preferably mortar or concrete, in particular shotcrete, using sound, preferably ultrasound waves which penetrate the material and are continuously measured and analyzed. In particular, the invention relates to an apparatus, to a measuring device, and to a method for determining the dynamic elastic modulus of a material using the apparatus.
