Concerns about climate change have heightened interest in sustainable construction materials. Ground granulated blastfurnace slag offers civil engineers a highquality, environmentallyfriendly material, which can replace much of the Portland cement used in concrete. This article looks at its manufacture and environmental impact and gives examples of its use.
Embodied Carbon (aka Embodied Energy) EPDs
Embodied carbon normally encompasses both CO2 and other greenhouse gases, and includes emissions from all the extraction, transport and manufacturing processes required before products are ready at the factory for delivery to the customer – such an assessment is known as "cradle to gate".
