- Test cylinders placed as near to the product that it represents as possible (field cured as per ACI standards)
- Test cylinders allowed 20 hours of cure time before testing
- Test cylinders broke on hydraulic cylinder press, following PCI standards, and compressive strengths were recorded as follows
