ASTM C42 is the test method for obtaining, preparing, and testing drilled cores from concrete for length, compressive strength, and splitting tensile strength. To match this to your program, talk with our team.
What ASTM C42 Covers
It provides direct measured strength from cores taken out of an existing structure or precast element, used when in-place concrete performance must be verified.
How the Test Is Run
A drilled core is trimmed, its ends prepared, and it is loaded in compression or split diametrically, and the strength is calculated from the failure load and dimensions.
Why It Matters
Core strength verifies in-place concrete when cylinder data is unavailable or disputed; high-force compression capacity and correct end preparation are essential.
