CRC i2® application cases - The potentials of our concrete

Aug 30, 2017  Firstly, to produce elements with comparable performance, say 10 m² of balcony, much less CRC i2® is needed because of the strength and ductility. Therefore, even though UHPC’s including CRC i2® contains more cement pr. m³ than conventional concrete (cement is the main source of CO 2 emissions from concrete), the net result is that more ...

CRC - basic properties - The potentials of our concrete

Mar 07, 2017  CRC – the type of concrete used by Hi-Con – typically has a compressive strength measured on 100×100 mm cubes of 150 MPa, but as our design strength relates to compressive strength measured on 150×300 mm cylinders, we use a characteristic strength of 110 MPa. Using the same type of cementitious matrix we could also achieve 300 MPa, but ...

World leaders in UHPC? - The potentials of our concrete

Mar 09, 2017  CRC – short for Compact reinforced Composite – is the special type of UHPFRC used at Hi-Con. It was developed (and patented) at Aalborg Portland by Hans Henrik Bache in 1986 as the first UHPC, combining a compressive strength of more than 150 MPa with high tensile strength and ductility – due to a high content of steel fibres – and ...
