The Automation Revolution: Concrete Compression Machines
A typical compressive strength test for a concrete cylinder takes only a few minutes, but much of that time is spent watching the compression machine and guiding it through the test procedure. The test method permits the application of the first half of the estimated peak load at a higher speed before completing the test at the specified rate.
