The Sarjeant Company is the only local ready mix producer with a concrete lab in Simcoe County. We offer a variety of testing services to ensure your project meets specifications.
See below for a list of services our Quality Control department provides. Please contact us for further information.
Testing procedures have been provided, with permission, by the RMCAO. Testing must be conducted by a certified technician* and in accordance with CSA A23.1/.2**
*Field Testing Certified Technician
To comply to CSA A23.1/.2, all field testing personnel shall be certified. A CSA or ACI certificate clearly stating name of individual, certified company of employment, date of expiry, and the tests for which the individual is certified shall identify all field test personnel.
**IMPORTANT NOTE
Concrete tests not sampled, made, cured and handled in accordance to CSA A23.1/.2 shall not be considered valid and will not be accepted by the Ready Mixed Concrete Producer.
If there are any questions, or any occurrences of improper field testing of concrete, please contact your Concrete Supplier or the Ready Mixed Concrete Producer.

A concrete slump test is a test for determining the consistency/workability of concrete by measurement of the spreading of a specified volume of concrete over a flat plate.
The slump test result is essentially a measure of the behaviour of a self compacted cone of concrete under the influence of gravity, which is directly proportional to the workability or dampness of the concrete. It is typically used in the field to determine the workability of a single batch as well as the consistency between multiple batches.
The air content test determines the air content of plastic concrete using pressure in a vacuum, and is based on the pressure-to-volume relationship of Boyle's Law.
Pressure is applied to a sample of concrete using an aparatus similar to the one to the right, which compresses the entrained air in the pores. The apparatus uses the change in the known volume of air to calculate the air content of the concrete mix.

Compressive strength is the capacity of a material to withstand axially directed pushing forces. The concrete compressive strength test determines if the mix meets the specified strength by subjective cast cylinder samples to crushing loads.
Sarjeants offers a range of other tests, including:
- Concrete Yield Test
- Rapid Chloride Permeability Test (“Coulomb Test”)
- Alkali-Silica Reactivity Test (ASR)
