Abstract
An experimental device enabling to study the rheological behaviour of setting heterogeneous materials is first presented. Measurements are achieved by means of vibration tests using acoustic waves at low frequency (100 Hz–1 kHz). The results are presented for different mixtures of water-granulates-binders and gas bubbles: mortar and cellular concrete (different formulations). From the measurements of celerity and damping coefficients, various analyses led to quantify the evolution of the complex œdometric modulus of the material and the viscoelastic modulus of the interbubble matrix.
