Test Method Title
Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens
Reference Number
ASTM C39
Material
Concrete
Test Property
Compressive strength
Description of Test
Cylinders cast and cured in the field are transported to the laboratory within 24-to-48 hours of production. Cylinders are then cured in water (or high-humidity chamber) for the specified curing period (e.g., 7-days, 28-days, etc.). On the date the cylinder has cured for the specified period of time, the cylinder is removed from the water tank and tested in compression with strength and failure mode reported.
Number of Test Specimens
1 but typically several specimens per set of cylinders
Test Specimen Size
Typically 4" x 8" or 6" x 12" cylinders
Keywords
