Project case studies

Our cements feature prominently in many landmarks, including some of our most recent projects below. These projects showcase the versatility of our products and the variety of projects we have undertaken.

Chinderah Freeway

The new Yelgun to Chinderah freeway in Northern NSW will save travelling time and lives. Construction of the 28.5 km, 4-lane freeway and 54 bridges required consistent high volume supply capabilities to produce over 230,000 cubic metres of concrete. The concrete incorporated 54,000 tonnes of cement and 22,000 tonnes of fly ash and was mixed on-site in two batch plants. A special Ash-Lime-Slag blend and General Purpose cement were also supplied for in situ stabilisation on the project. Cement was transported by road to the site from Brisbane and fly ash efficiently transported by road and rail from Eraring, NSW. The provision of four 150 tonne capacity mobile super tankers saved the construction company from investing in additional storage and ensured timely product supply.

Bolte Bridge

The striking six-lane Bolte Bridge connects the Tullamarine and Westgate Freeways in iconic Melbourne fashion. The bridge was ‘incrementally launched’ to meet pre-cast segments of elevated freeway. Over 50,000 tonnes of Goliath Cement was used for the bridge, the submerged foundation island and the 3,600 precast freeway segments. Ship loads of cement were delivered without any delays from Railton to Port Melbourne by the MV Goliath. From there it was distributed by cement tanker to the various concrete plants required for the large project. Consistent product quality was imperative in the production of the many pre-cast segments to ensure that they quickly reached the specified strength.

The $280 million redevelopment of Brisbane’s Suncorp Stadium has created the first true ‘coliseum’ rugby ground in Australia. The structure consists of four concrete elements which are each 45 metres square and seven stories high. These are connected by way of a steel column and beam and concrete plank system. 40,000 cubic metres of concrete was used in this construction. The majority of concrete incorporates cement from Bulwer Island and fly ash from Tarong, delivered to the premix concrete plants by Cement Australia’s pneumatic tanker fleet. The huge project includes over 25,000 square metres of pre-cast concrete planks and 5,600 square metres of pre-cast façade.

Green Park

The Sydney Airport Link Rail Tunnel from Tempe to Green Park was the first pre-cast concrete tunnel of this type in Australia. Innovative engineering solutions were employed to bore through soft clays and shale using an 80 metre long tunnel boring machine (TBM) weighing 1,700 tonnes. The 11 metre diameter tunnel lining of pre-cast concrete segments was constructed behind the TBM as it moved forward. 30,000 tonnes of Ocean Cement, a slag-cement blend, was manufactured at Newcastle and transported by road to the pre-casting plant at Tempe. State-of-the-art blending facilities, stringent quality control and availability of large storage silos ensured a quality product and continuity of supply throughout the project.
