Most pavement PCC has a compressive strength between 20.68 and 34.47 MPa (3000 and 5000 psi) (ACPA, 2001). High-strength PCC (usually defined as PCC with a compressive strength of at least 41.37 MPa (6000 psi)) has been designed for compressive strengths of over 137.90 MPa (20,000 psi) for use in building applications. Test Procedures
Free online knowledge for the paving industry. Flexural strength (sometimes called the modulus of rupture) is actually a measure of tensile strength in bending. PCC flexural strength testing is carried out on a 40 x 40 x 160 mm (1.57-inch x 1.57-inch x 6.30-inch) cement mortar beam. The beam is then loaded at its center point until failure.
