NewCem Plus


Lafarge 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 when correctly proportioned, can often be selected as an alternative SCM where fly ash is specified.


NewCem® Plus Advantage

When portland or portland limestone cement is mixed with water, most of the cement forms insoluble Calcium-Silicate-Hydrate (C-S-H) gel; Calcium Hydroxide - Ca(OH)2 is also formed as part of this reaction. When NewCem® Plus is introduced into concrete, it reacts with the Ca(OH)2 to form additional C-S-H gel. In a properly proportioned mix, NewCem® Plus can improve many of the properties of concrete, including workability and consolidation, flexural and compressive strengths, pumpability, and decreased permeability.

Lafarge NewCem® Plus has:

  • 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. These factors can allow for more economic mix design development.

NewCem® Plus provides a significant contribution to sustainable construction due to the high replacement rates possible. Its use in concrete production consumes less energy and offers improved efficiency and building performance. NewCem® Plus can contribute to the achievement of LEED (Leadership in Energy and Environmental Design) points.
