✦ Synopsis
Fresh cement slurries typical of those used in the oil industry during drilling operations are assessed for the growth of structure in the first few hours after mixing by the use of shear modulus and ultrasonic pulse velocity measurements. It is shown that during the first two hours, the shear modulus technique is a much more sensitive measure of the developing physical structures but after initial set the ultrasonic pulse velocity is an effective method of differentiating between different mix formulations.
