Loeriesfontein Wind Farm

The Department of Science and Technology has certified this project as groundbreaking with significant tax relief on the application of the materials technology.

Standard concrete uses up to 95% cement replacement.
Significant reduction of the carbon footprint of concrete (in excess of 70%).
The first high fatigue structure in the world will be constructed with 100% cement replacement.

Case Study

Case Study: Loeriesfontein Wind Farm

With using ARC technology, Murray & Roberts were able to use water with high sulphates and nitrates as mixing water for the concrete. This water would have been considered inadequate as it is not potable and the water would have to have been transported from approximately 100km away from the site, Loeriesfontein is in the desert.

Over the 18 months of construction, approximately 15 730 kilolitres of water would have been transported via tanker which equates to 4 loads of 10 ton water bowsers per working day travelling 200km for the 18 month period.

Based on 35%: 65% ratio of PFA: Portland cement at Noupoort Wind Farm also designed through ARC technology:

Reduction of 30.5% of carbon footprint related to all materials for concrete.
On award, an estimated concrete material CO2 equivalent of 2 472 324 kg, based on 35%:65% ratio of PFA: Portland cement at Noupoort Wind Farm also designed by ARC technology.
On as-built, through application of ARC technology, final estimated concrete material CO2 equivalence of 1 717 948 kg.
Total saving of 754 376 kg of CO2.
Economical saving of R4.8M, Increase of profit of 7.4%.
Total concrete 65 000m³.
