The
Cement & Concrete Association of New Zealand (CCANZ)
and Concrete3 have produced a short film
that demonstrates how concrete meets the current global
imperative of operating in a sustainable manner.
By
using the medium of film to highlight innovations
and efficiencies in concrete's manufacture, along
with its attributes in a range of applications, Concrete
for a Sustainable World seeks to motivate an
informed understanding of concrete's contribution
to sustainable building solutions.
The
ten-minute film offers an insight into the benefits
afforded by building with concrete, and will be of
interest to architects, engineers, contractors and
their clients, as well as anyone involved in the design,
construction or operation of buildings and infrastructure.
Updated CCANZ Position on
Public Policy Issues - June 2009
As
there are a number of significant policy issues currently
affecting the New Zealand building and construction
sector, CCANZ has updated the document - New
Zealand Concrete Industry Position on Public Policy
Issues.
By summarising the Government’s policy platform relating to a number of key sector issues such as housing affordability, infrastructure investment, emissions trading and building regulation, and presenting the industry’s position on them, the document seeks to inform further discussion and associated policy development.
CCANZ
receives numerous calls asking about the appropriate
time to overlay concrete slabs with moisture sensitive
flooring materials. To provide guidance to designers,
specifiers and contractors, CCANZ has developed IB91
Applying Moisture-sensitive
Floor Coverings and Adhesives to Concrete Slabs.
The
IB outlines how moisture in concrete slabs can cause
problems to moisture-sensitive floor coverings and
adhesives. The IB also stresses the importance of
understanding the sources of moisture in a concrete
slab, the correct design of slabs, the Building Code
and Specification requirements, and the measurement
and testing methods.
Media Release : A Concrete National Cycleway Will Save Jobs
The
concrete sector has welcomed the Government's commitment
to a national cycleway, and believes that concrete
must be considered as a suitable construction material.
Media Release
: Concrete Sector Welcomes New Government Infrastructure
Package
The
Cement & Concrete Association of New Zealand (CCANZ)
Chief Executive, Rob Gaimster, has praised the Government’s
fast-tracking of $500 million worth of infrastructure
projects recently announced.

– Concrete Pavements for Roundabouts &
Intersections
Pavements within turning areas such as intersections
and roundabouts are subject to very high shear
forces from the tyres of vehicles, especially
trucks.
Horizontal
loads from the outer tyre imparted on the pavement
during a tight turning movement are as much
as 80% of the static load. This turning load
causes surfacing and base shear failures in
thin surfaced granular pavements. As a result,
intersections and roundabouts of traditional
granular pavement construction need regular
reconstruction.
Concrete
pavements at intersections and roundabouts will
prevent surface and base failures, as well-designed
and constructed concrete pavements will last
at least 40 years without needing reconstruction.
Consequently the life cycle costs of concrete
pavements are lower than traditional granular
pavement.
This IB
describes the benefits and use of concrete for
roundabouts and intersections. Download.

– Cement Stabilisation
Over the last ten years heavy vehicle traffic
in New Zealand has doubled, putting increasing
demands on our road pavements. As a result,
more pavements now fail before they reach the
end of their design life. Cement stabilisation
is one method to prevent these failures.
Cement
stabilisation is an ideal method to enhance
the properties of marginal materials so that
they can be used instead of premium quality
aggregates even in the highest stressed areas
of a pavement.
Although
cement stabilisation has been used for over
60 years in New Zealand, improvements in stabilising
equipment have led to a recent resurgence of
interest.
In response, specifications are changing to
acknowledge and allow innovative uses of alternative
materials and plant to produce cement stabilised
mixes that are suitable for highly trafficked
roads.
This IB
outlines the principles of cement stabilisation,
including in-situ and plant mix processes, modified
and bound materials, and the principles of designing
stabilised pavements. Download.
Research
Demonstrates Importance of Cement & Concrete to NZ
Economy
Research into
the importance of the cement and concrete industry
to New Zealand’s economy has found it contributes
nearly $3 billion towards GDP.
A New Zealand
Institute of Economic Research (NZIER) report shows
that for the year ending March 2006, the value of
the industry’s output was $7.4 billion. This activity
supported 24,000 jobs and created a value add of $2.8
billion – about 2% of New Zealand’s GDP.
CCANZ chief
executive Patrick McGuire believes the research illustrates
just how significant the cement and concrete industry
is to the nation’s economy. “A primary aim for us
is to ensure that cement and concrete are truly sustainable
– environmentally, socially and economically. The
NZIER research proves the industry is more than meeting
the economic part of this objective,” Mr McGuire said.
CCANZ Chief Executive,
Patrick McGuire, recently outlined the advantages
of concrete road safety barriers over the currently
preferred wire rope option, in New Zealand two most
widely circulated daily newspapers:
Wire-rope barriers -

Concrete Masonry : Compliance
with Clause H1 – Energy Efficiency
The New Zealand
Building Code (NZBC) Clause H1 has as its objective
the efficient use of energy in buildings. The performance
requirements as they relate to housing and amended
on the 13 August 2007 are, ‘Buildings must be constructed
to ensure that their Building Performance index (BPI)
does not exceed 1.55’.
