ABSTRACT:
A system for non-destructively measuring the strength of a cement slurry sample includes an elongate sample container for receiving a cement slurry sample. The elongate sample container has a mass mounted at its first end. A transducer mounted at a second end of the elongate sample container vibrates the elongate sample container and mass. The elongate sample container, mass and transducer have a known resonance. The system calculates the strength of a tested cement slurry within the elongate sample container as a function of variation in resonance of the elongate sample container, mass and transducer.
