Claim:
1. A method for determining mechanical parameters of a cement system of initial composition C 0 and of fineness Φ, as a function of time, and as a function of fineness of the cement system, pressure and temperature, comprising the following steps: (A) determining a degree of hydration of the cement system as a function of time α(t) from a velocity of a compression waves as a function of time V (B) determining the degree of hydration α(t) as a function of desired values of fineness Φ (C) determining a composition of the cement system as a function of time C(t) and as a function of desired values of fineness Φ (D) determining at least one mechanical parameter of the cement system as a function of time, and as a function of the desired values of fineness Φ
