A new low carbon cement solution has been launched by Aggregate Industries business Lafarge Cement. Lafarge Endure SR is a high performance, low carbon, CEM II blend cement. It blends Portland fly ash (PFA) with clinker, which results in a lower embodied CO2, as well as improved plastic and hardened properties when used in concrete.
Unlike a CEM I blend, Lafarge Endure SR is suitable for all ground types. Sulphates in the ground can negatively impact CEM I blends. However, Lafarge Endure SR is resistant to sulphates, allowing contractors and suppliers to scope a wider variety of projects including those that may have previously been hindered by ground type.
Once hardened, Lafarge Endure SR can be used to DC-4 durability standard and can help increase the life of the structure thanks to its resistance to carbonation and chloride and sulphate attack. This makes it ideal for practically any situation, from producing ready-mixed and precast concrete, to marine, grouting and tunnelling applications.
“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.
“In addition to its lower embodied CO2, Lafarge Endure SR uses 10 percent 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,” he added.
