Sarjeants and Custom Concrete Northern are centrally located to deliver the best services for urban or remote projects throughout Ontario.
Concrete Products & Services
The Sarjeant Company Ltd. and Custom Concrete Northern have been producing, and delivering ready-mix concrete since 1956 and 1976 respectively. Over that time we have fulfilled the requirements of countless projects with both our commercial and residential customers. Sarjeants offers a wide range of concrete mixes for a variety of applications.
Customization of any mix is available and with a knowledgeable sales team backing our fleet you can be assured that your project will be provided with the correct mix to maximize your investment.
We offer a variety of testing services to ensure your project meets specifications. RMCAO certified Quality Control Technicians are kept on staff to ensure consistency throughout product delivery.
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.
AIR CONTENT TEST
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. Air is put into concrete to allow for moisture to absorb into the air bubbles during the freezing and thawing cycles, this avoids potential cracking or spalding.
Pressure is applied to a sample of concrete using an apparatus 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 Test
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 crushing subjective cast cylinder samples.
