Mechanical properties


Generally, the compressive strength is the property which is first discussed with regard to High Performance Concretes, but while this property is certainly impressive for CRC, the ductility, durability and strength in bending are often considered more spectacular.

Properties are dependent on the type of aggregate, the amount of main reinforcement and fibre reinforcement, but a typical range of properties is shown in the table below.

Compressive strength

140-400 MPa
Bending strength 30-200 MPa
Young's modulus 40-80 GPa
Density 2600-3000 kg/m3
Durability Absolutely frost resistant, no corrosion in reinforcing bars observed in any of the tests carried out since the development of CRC in 1986
