Cemex USA is offering CemSlag, an eco-friendly cement solution which it claims improves the quality of concrete and reduces greenhouse gas emissions.
The company says CemSlag – a hydraulic cementitious material – is created when blast-surface slag is finely ground to a size to produce a binder suited for concrete. The material is expected to offer permeability for increased resistance to chemical attack, reduced heat of hydration thereby reducing thermal cracking.
Francisco Rivera, Cemex USA vice president cement sales—West Region, says: “The fine particles of CemSlag help create a fluid paste, allowing for easier and improved finishing properties. Concrete produced from CemSlag is also lighter in colour, which makes concrete structures built with this cement more effective in reflecting light, and therefore heat – structures become more energy efficient.”
CemSlag is currently CalTrans approved and available in bulk from Cemx for immediate use in California.
