This article focuses on the computation of the sound velocity through slurries and hardened products. The purpose is to use the sound velocity to quantify the composition of the fresh slurry as well as the hardening and hardened - porous - material. Therefore the volumetric models for hydration of calcium sulphates given by Brouwers /1/ is integrated with sound velocity equations found in literature. Furthermore the derived model is compared with experimental data. This shows that the model of Robeyst et al. /2/ gives good results for the computation of sound velocity through slurries, while the model of Ye /3/ give good results for the computation of sound velocity through hardened porous material
