Video: Concrete Cylinder Testing
Superior Walls promises each precast concrete foundation wall meets or exceeds 5000psi in strength.
To make sure we adhere to this strict promise, we evaluate each batch of concrete delivered to our Beausejour, Manitoba plant.
Our evaluation methods are simple and effective. We form samples into cylinders from each batch of concrete. The cylinders are made to be the approximate size of a bread box. Samples are tested at different time intervals by a certified technician to ensure concrete strength is up to our standards. The one-day break must exceed 2600psi and the 28-day break must be a minimum of 5000psi.
See our 28-day high pressure test in the video below.
The cylinder breaks at 12,5465lbs of pressure. With conversion, this works out to be just over 9,900psi. (video has no sound)
