This paper evaluates the performance of steel furnace slag (SFS) coarse aggregate in blended slag and low calcium fly ash geopolymer concrete (GPC). The geopolymer binder is composed of 90% of low calcium fly ash and 10% of ground granulated blast furnace slag (GGBFS). Mechanical and physical properties, shrinkage, and detailed microstructure analysis were carried out.
This research explores the carbon impact of current Value Engineering (VE) practices in Australia. To accomplish this goal, a complex mixed-use building in Sydney was modelled to determine the capital material costs and initial embodied carbon emissions before and after the VE process.
The Carbon Value Engineering project aims to maximise the reduction of embodied carbon in the built environment. Rather than proposing a new process for these reductions, it adapts the industry-standard practice of value engineering (VE) for integrated carbon and cost minimisation. The project set out to answer two research questions:
