Both of our laboratories are certified by CCIL (Category 0) for concrete. Field concrete tests include the measurement of slump, entrained air content and concrete temperature. A standard of three cylinders are cast for determination of compressive strength, typically one cylinder at 7 days and two cylinders at 28 days. Certain concrete mix designs require 56 days compressive strength as well. Cast cylinders are cured in a temperature controlled curing tank until the test date. Cylinders are then measured to ensure CSA compliances and to ensure quality, and broken to determine maximum compressive strength.
Our laboratories have the capability to end-cap cylinders with a high strength sulphur compound or grind cylinders to prepare them for compressive testing.
