We take our role as an industry leading builder seriously. We actively invest in initiatives with our clients to improve construction sustainability and associated waste management on our projects.
Most recently, we partnered with the Elvin Group to deliver a Green Star recognised Concrete Mix for the Aunty Agnes Shea High School (named after the late senior Ngunnawal Elder) in the ACT.
A total of 837 tonnes of CO2-e were eliminated in the binder formulation processes – with an overall reduction in cement consumption of 31%.
We caught up with Njoud Willans, Technical Engineer at The Elvin Group to find out more.
“Designing concrete for sustainability involves several parameters that reduce the environmental impact while maintaining performance.” said Njoud.
“The key design parameters used in our Green Star concrete mixes are, use of Supplementary Cementitious Materials (SCMs): Incorporate SCMs to replace a portion of Portland cement which reduces the carbon footprint associated with cement production, use of manufactured sand: Using manufactured sand in concrete offers several environmental benefits, such as protection of natural sand resources, minimising waste, and reduction in transportation emissions, and use of recycled water in concrete production.”
Jemma Butt, Hindmarsh Project Manager said, “The team have been fascinated by the process employed by the Elvin Group to improve the sustainability of a very historic building material. The use of ‘concrete’ in construction can arguably be dated back to a time before even the pyramids were built. It is amazing to witness its evolution as a construction material to provide a greener solution for future generations.”
