Lafarge Cement – part of Aggregate Industries (AI) – has launched Lafarge Endure SR; a high performance, low carbon, CEM II blend cement.
Steve Curley, commercial director at AI, says: “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.”
AI says Lafarge Endure SR blends fly ash with clinker, which results in a lower embodied carbon dioxide (CO2) as well as improved plastic and hardened properties when used in concrete.
Lafarge Ensure SR’s resistance to sulphates allows contractors and suppliers to scope a wider variety of projects including those that may have previously been hindered by ground type, AI adds.
Once hardened, Lafarge Endure SR can be used to DC-4 durability standard and can help increase the life of the structure due to its resistance to carbonisation and chloride and sulphate attack.
According to AI, this makes it ideal for practically any situation, from producing ready-mixed and precast concrete, to marine, grouting and tunnelling applications.
“In addition to its lower embodied CO2, Lafarge Endure SR uses 10% less water than CEM I to reach workable consistency and offers improve pumpability and mixing efficiency. Each of these benefits adds up to a cement that is truly forward-thinking,” Curley adds.
