properties of carbon cast concrete

The use of carbon fiber grid over conventional reinforcement yields a number of unique properties to CarbonCast components: [7]

Lower weight - When carbon fiber grid replaces steel mesh in the face of concrete products, manufacturers can use less concrete cover to protect the mesh from corrosive elements. Non-corrosive carbon fiber eliminates the need for extra concrete Improved thermal performance - The relatively low thermal conductivity of carbon fiber permits CarbonCast components to provide higher R-values than conventional precast concrete Improved strength - Carbon fiber is four times stronger than steel by weight providing better surface crack control when used as secondary reinforcing and 100% composite action when used as a truss in insulated wall panel Comparable cost - Many applications receive savings in foundation and super structure (reduced weight), energy costs (insulation) and maintenance (reduced corrosion

T30 building china

30-storey prefab tower constructed in
15 days
On the 18th January China’s latest impressive
structure will open for business. This is no
‘iconic’ or ‘landmark’ tower, glistening
commercial building or tallest spire. What sets
this structure apart is its breakneck construction
speed - the entire 30-storey building was
erected in just 15 days.
The T30 Hotel is the latest project of Zhang Yue
of the Broad Group - a Chinese construction
company specialising in sustainable building
design - and features quadruple-glazed windows
and 15cm-thick glass curtain wall insulation. The
prefabricated tower has been designed to be
highly sustainable both in construction and day-
to-day running, with a heat recovery system
and energy-saving lights throughout.
Zhang explains: “We need to speed up our
environmental thinking. We need buildings like
this all over China. In 2013 we will build 20
buildings a month and by 2014, we’ll be up to
50 buildings. China is 20-40 times more
polluted than Europe and that’s hurting our
health and will offset economic benefits of our
growth.”
Built by 200 construction workers in just 360
hours, the 17,000 sq m hotel has been tested
by the China Academy of Building Research and
can resist a magnitude nine earthquake. A six
minute time lapse video of the building’s
staggering construction speed has amassed over
two million hits on YouTube and spawned
countless blog posts, and Twitter is abuzz with
links to the film.
