NewCem® Slag Cement

Lafarge NewCem® slag cement is a finely ground, hydraulic cement produced from granulated blast furnace slag, a product of the iron-making process. NewCem helps achieve low permeability, resistance to chlorides, high sulfate resistance, resistance to alkali silica reaction, greater strength potential, lower temperatures for mass concrete, and improved workability. Concrete made with NewCem can be expected to be light in color.


Resistance to sulfate attack may vary according to the chemistry of the cement and the slag cement used.  Any combination of these materials should be tested to assure that desired sulfate resistance levels are achieved.  Consult a Lafarge Cement technical representative before using NewCem slag cement in applications that will be exposed to sulfate conditions.


NewCem provides a significant contribution to sustainable construction. The use of this material in concrete production consumes less energy and offers improved efficiency and building performance.  NewCem can be used to achieve LEED (Leadership in Energy and Environmental Design) points.
