ABSTRACT:
A method for sampling cement and determining the cement-to-water ratio includes use of a device having 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 hydroscopic filter surrounding the hydrophilic filter. As the sample is drawn into the chamber, it passes through the hydrophilic filter into the hydroscopic filter. The weights of the collected cement and water are then determined after taking into account the original weight of the filters.
