Sample submission

The test results and recommendations reflected in a Colas slurry design are based on, and are representative of, the aggregate sample(s) submitted for evaluation. It is therefore of utmost importance that submitted aggregate samples are representative of the stockpile/aggregate source intended for use.

No more than 15kg of aggregate is required in order to perform a slurry design. Should clients intend to use water from a potable source and ordinary Portland cement in their slurry mixture(s), samples of these constituents are not required.
