EU: Cembureau has responded to the European standardisation organisation Cenelec’s CEN/TC 350 ‘sustainability of construction works’ rules by amending its European Environmental Product Declarations (EPDs) for CEM I, CEM II and CEM III, corresponding to Portland cement, Portland-composite cement and blast furnace cement respectively. It says the update brings the three main cement types into ‘full alignment with the EU Commission strategy for a sustainable built environment.’

UK: Aggregate Industries has launched its Lafarge Endure SR, a CEM II blended cement product that uses fly ash. It says that the product has a lower embodied CO₂, has improved plastic and hardened properties when used in concrete and has enhanced suitability for all ground types. Lafarge Endure SR is resistant to sulphates, allowing contractors and suppliers to scope a wider variety of projects. It also uses 10% less water than CEM I products to reach a workable consistency and offers improved pumpability and mixing efficiency.

“As its name suggests, Lafarge Endure SR is designed to dramatically increase the longevity of the concrete it forms a part of. It is a great solution for contractors that want to reduce the environmental impact of their build while simultaneously improving its life span,” said Steve Curley, Commercial Director at Aggregate Industries.
