IB88 – 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 during stage 1 Harbour Link project , Mt Maunganui

IB89 – 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.

A trade exhibition with more than 80 exhibitors from around the globe will showcase the latest developments in concrete, concrete products and precast concrete industry.

As an introduction to the conference program, two technical courses on the production and application of self-compacting concrete, and the design and production of precast concrete will be held on March 30.

The ICCX Dinner Party, held on March 31 aboard a boat cruising Sydney Harbour, will offer plenty of opportunity for networking and socialising.

On April 2, following the two-day conference and exhibition, delegates are offered the chance to tour a range of precast plants across Sydney to view modern production techniques and practices.

Anyone who is involved in the concrete industry should take this unique opportunity to learn more about the latest developments in concrete technology worldwide. This is a must-attend event. As such, CCANZ has arranged for members to receive a 10% discount on exhibition stands and registration.

November Issue of Grey Matters

This month's issue of Grey Matters includes information on the following:

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.

Safer Roads	Absorbs CO2	Recyclability

The Concrete³ series of print advertisements has been expanded to include the above three attributes of concrete.

Brewery Project Takes Out First Ever Cement & Concrete Industry Sustainability Award

A unique building project using considerable quantities of recycled waste glass won the inaugural 2008 Concrete³ Sustainability Award in Rotorua on the evening of Friday 3 October.

Project Century, a brewery currently under construction in South Auckland, is a joint submission by Holcim (New Zealand) Ltd and Mainzeal Property & Construction Ltd for Lion Nathan. The project will use recycled waste glass as aggregate in the building’s concrete structures, and is due to open in 2010.

The award, which is part of the Concrete³ initiative launched last year by the Cement and Concrete Association of New Zealand (CCANZ), acknowledges companies whose product, programme or initiative demonstrates excellence in environmental, economic and societal sustainability.

The runner-up in the Concrete³ Sustainability Award was Wilco Precast Ltd, for Sinclair House in Whitianga – an energy-efficient holiday home understood to be the first house in New Zealand built entirely from lightweight precast pumice concrete.

Concrete³ Advertising Campaign Launched

Fire Resistance	Flood Protection	Thermal Mass

Using the proposition "Concrete - The Responsible Choice", a series of print advertisements demonstrating the sustainable properties of concrete began appearing in selected trade publications in February 2008.

The three samples above will soon be accompanied by advertisements that demonstrate concrete’s recyclability, CO₂ absorption capabilities and contribution to safer roads. Visit the Concrete³ website.

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’.

CCANZ voices regular opinion in New Zealand Construction News magazine

Since early 2007 CCANZ Chief Executive, Patrick McGuire, has commented on topical issues in the national trade publication New Zealand Construction News.

CCANZ release Key Government Issues paper

There are a number of significant policy issues affecting the New Zealand building and construction industry. CCANZ recently distributed a briefing paper to all Members of Parliament and select government departments and agencies, which presents CCANZ’s response to the Government’s policy platform on these key industry issues.

By discussing issues in areas such as sustainability, building legislation, infrastructure, standards and education, the briefing paper seeks to inform further debate and associated policy development. View the paper:
