Applications

In 2002 CRC was used in Denmark for more than 500 balcony slabs on a number of different projects, for staircases of all types and for beams and slender columns (120x120 mm cross section).

The development of CRC was based on the experience obtained from working with the so-called DSP-materials, developed by Aalborg Portland in 1978.

These High Performance Concretes (150-300 MPa compressive strength) have been extensively used for floors, abrasion resistant linings, corrosion protection and in the security industry by Densit A/S. The CRC concept, marketed by CRC Technology, is well suited for structual applications due to the large fibre contents which provide ductility and tensile strength.

CRC has often been used for problem-solving, where a solution in steel or concrete has not been quite satisfactory. Examples of this have been the replacement of cast iron drain covers in the Great Belt Link or repairs.

As CRC is becoming known in the building industry, it is now more and more common that CRC is also considered in the early stages of design, and utilised to achieve slender and elegant structures or for small and simple connections with CRC JointCast which makes it possible to combine the advantages of pre-cast production and the properties of an in-situ cast structure.

In Denmark CRC elements are produced by the pre-cast producers Beton-Tegl A/S and PL Beton A/S. Hi-Con Aps has recently started production as well, and intend to have CRC elements as their main product.
