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
