Abstract
An apparatus for determining an initiation point of cement curing, with a vessel for containing at least a portion of freshly mixed cement, means for passing an electric signal through the cement, means for detecting an abrupt change in a dielectric or electric property of the cement as a result of the electric signal and a display unit for displaying the initiation point of polymerization of the cement from the abrupt change in the dielectric or electric property detected, the change in the dielectric or electric property being a phase shift in the electric signal passed through the cement or a change in capacitive properties of the cement or a change in resistivity of the cement.
