Determining Required Concrete Cylinder Size Acceptable Methods for Permitting the Use of 4-in. x 8-in. Cylinders for Aggregate Grades 2 and 3 When conducting compressive strength testing, numerous studies have looked at the effects of deviating from the requirement to
Are the days of the 6x12 concrete cylinder for compressive strength testing coming to an end? Newer data has shown little difference between measured strength for 4x8 concrete cylinders compared to 6x12s, so what's holding up this change?
