Cylinder Tests will be performed in association with each bid unit. Concrete sampling and testing
shall be performed in accordance with applicable ACI and ASTM standards.
• After proper curing time, cylinder testing will include cylinder breaks. One 7-day break, three 28-
day breaks, and 1 hold cylinder. The hold cylinder may be disposed of once 28-day results have
