ABSTRACT:
A device for sampling cement and determining the cement-to-water ratio includes an elongated, hollow probe for insertion into a batch of cement mix. The probe has an aggregate separator at one end and a chamber at the other end. A manually actuated piston subjects the chamber to a vacuum to draw the cement mix through the aggregate separator and through a sand collector into the chamber. A hydrophilic cement filter surrounds the chamber with a hygroscopic filter surrounding the hydrophilic filter. As the sample is drawn into the chamber, it passes through the hydrophilic filter into the hydroscopic filter until the latter is saturated. The combined weight of the hydrophilic filter and the cement deposited thereon is measured and the weight of the filter is subtracted to determine the weight of the collected cement.
