Transurban use Holcim's ViroDecs EcoMax-70 to reduce embodied carbon on new cycleway in Greenways Esplanade Park
In collaboration with Transurban, Holcim developed ViroDecs EcoMax – 70, an innovative lower carbon ready-mix concrete mix, designed specifically for the construction of the Greenways Esplanade Park cycleway in Parkinson, south of Brisbane.
The mix design replaces 70% of the cement content with supplementary cementitious materials (SCM), reducing emissions by over 50% in comparison to the Australian average1.
“The concrete mix developed for the project has the lowest level of General Portland cement that has ever been used in a wearing course pavement application supplied by Holcim in Australia. Its use is made possible by collaboration with the placers, contractors, councils and all key stakeholders” says Paul Rocker, National Materials Technology Manager for Holcim.
Holcim developed this specific concrete mix to meet the sustainability objectives of the project and align with Transurban’s long term goals to reduce the greenhouse gas emissions of their construction materials.
“The team has been very happy with the results. Being able to achieve such a high level of SCM replacement and reduction in embodied emissions is very exciting. We’ll be considering how we can use this product on future projects,” says Jessica Cairns, Senior Sustainability Advisor for Transurban.
