Lafarge Cement, which is part of Aggregate Industries, launched Lafarge Endure SR – a high-performance, low-carbon CEM II blend cement.
While traditional CEM I blends use virgin clinker to produce the finished cement, Lafarge Endure SR blends fly ash with clinker, which results in a lower embodied CO2, as well as improved plastic and hardened properties when used in concrete.
“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.
Curley continued, “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.”
Another benefit is its suitability for all ground types. Sulfates in the ground can negatively impact CEM I blends. However, Lafarge Endure SR is resistant to sulfates, allowing for use in 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 sulfate attack.
This makes it ideal for almost any situation, from producing ready-mixed and precast concrete to marine, grouting and tunneling applications.
