Online CPD: Cementing Environmental Improvements

Available until 19th May 2021

Concrete is the most widely used man-made material in existence second only to water as the most-consumed resource on the planet. The key ingredient, cement, is estimated to produce about 8% of the world’s carbon dioxide emissions and as we grapple with a climate emergency it’s vital we consider options which are more environmentally friendly.

RSUA organised this one and a half hour seminar in partnership with Ecocem Ireland to provide insight into the current challenges and possible opportunities to achieve more sustainable construction. This seminar set out the challenges around concrete/cement and its carbon impacts followed by an explanation of the role partial cement replacements such as Ground Granulated Blast Furnace Slag can play in delivering a lower carbon footprint and achieving more sustainable buildings.

Course content

This seminar covered the following topics:
