Pre-cast
custom designed elements -staircases offer light and
slender structures, excellent quality and very smooth
surface finish. Eliminate complex on-site shuttering and
the delays that arise with site poured concrete. Speed
construction work and provide safe, immediate routes
between floors under construction. Once they have been
hoisted into place and suitably protected, they are
available for use.
Competitiveness
and innovation in building is largely driven by
development of innovative building products and systems.
With the increasing challenges of more sustainable,
durable and adaptable buildings.
Introduction
CRC, where ductility is achieved through incorporation of
a large content of short, stiff and strong fibres. This
ductility combined with high strength (150-400 MPa) and
exceptional durability makes it possible to utilise a
large amount of reinforcement, thus giving new structural
possibilities compared to conventional concrete.
The
possibility of having another alternative to steel and
concrete provides designers and builders with more
freedom in design, giving better and more cost effective
solutions.
CRC was
developed in 1986 by Aalborg Portland, but has only been
commercially available for 7-8 years. The first
applications have been for in-situ cast joints and tunnel
linings..
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 Joint-Cast which makes it possible
to combine the advantages of pre-cast production and the
properties of an in-situ cast structure.
