Test on Hardened Concrete The Concrete Network

Core diameters should be a minimum of two times the maximum aggregate size. The preferred core diameter for a compressive strength specimen is three times the maximum aggregate size of the concrete (see section 7 of ASTM C 42). Lengthtodiameter ratios are ideally 2:1, but this test method provides correction factors for ratios as low as 1:1.
