Lafarge Cement, part of Aggregate Industries, has launched Lafarge Endure SR. This is 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 portland flyash with clinker, which results in a lower embodied CO2, as well as improved plastic and hardened properties when used in concrete.
A benefit of using this new blend over a CEM 1 blend is that it is suitable for various ground types. Sulfates in the ground can negatively impact CEM I blends. However, Lafarge Endure SR is resistant to sulfates, allowing contractors and suppliers to scope a wider variety of projects, including those that may have previously been hindered by the 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 suited for a variety of situations, from producing ready-mixed and precast concrete, to marine, grouting, and tunnelling applications.
“As its name suggests, Lafarge Endure SR is designed to increase the longevity of the concrete it forms a part of,” said Steve Curley, Commercial Director at Aggregate Industries. “It is a great solution for contractors that want to reduce the environmental impact of their building while simultaneously improving its life span.
“In addition to its lower embodied CO2, the blend uses 10% less water than CEM I to reach a workable consistency, and offers improved pumpability and mixing efficiency. Each of these benefits adds up to a cement that is forward-thinking.”
