NewCem® Plus

The Perfect Mix

Lafarge Canada's NewCem® Plus is a controlled interblend of Lafarge fly ash and ground granulated blast furnace slag (GGBFS) that allows for more efficient and cost-effective concrete applications.

NewCem® Plus meets or exceeds all of the requirements of CSA A3000 and ASTM C1697 for a blend of supplementary cementitious materials and can often be selected as an alternative SCM where fly ash is specified.



  • Superior performance
  • Suitability for use in virtually all concrete and concrete product applications such as ready-mix, cast-in-place, pre-cast, pre-tensioned members, post-tensioned members and tilt-up construction solutions
  • Compatibility with a wide range of additives and admixtures
  • Typical replacement rates of NewCem® Plus are higher than those achievable when using fly ash as an SCM, and later age strengths are higher
  • Can allow for more economic mix design development

The NewCem® Plus Advantage in Concrete

When Portland or Portland limestone cement is mixed with water, most of the cement forms an insoluble gel known as calcium-silicate-hydrate (C-S-H) as well as calcium hydroxide (Ca(OH)2). When NewCem® Plus is introduced into concrete, it reacts with the Ca(OH)2 to form additional C-S-H gel.

The power of NewCem® Plus enhances various concrete properties, including:

  • Workability and consolidation
  • Flexural and compressive strengths
  • Pumpability
  • Reduced permeability
