on determination of compressive strength on HSC cubes of different edge sizes will be presented. The concrete mix tested is called HSC (not HPC), because no properties other than compressive strength were measured. The composition of concrete was intentionally modified to decrease the compressive strength of some specimens under 160 MPa.

Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc'. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

However, if the designed concrete strength is 100MPa, under the same force (about 2,000kN) supplied by the machine, the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube. Therefore, 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cubes. Sales Online
