A method for testing compressive strength of multiple molds filled with a liquid settable grout wherein samples of the liquid settable grout are taken at selected filling intervals and poured into a container, and the container is sealed and the time, date and location information regarding the mold then being filled is recorded on the container. The sample container is then left in the same environment as the mold being sampled. A curve is generated which projects a final compressive strength based on compressive strengths at various cure times. The sample is removed from its container after a selected cure time and subjected to a series of Schmidt hammer tests, and these compressive strength readings are used to determine the projected final compressive strengths of the sample based on the cure time from the established curve. |
