Cemfree Ultra-Low Carbon Concrete

Zero-cement, alkali-activated cementitious material (AACM) binder, of which 95% is ground granulated furnace slag (GGBS) and 5% is the activator. Designed to activate pozzolanic materials to create a cement free binder which can replace a variety of cement types and produce an ultra-low carbon alternative to concrete mix designs that traditionally use Portland cement.

Similar in structure to autoclaved aerated concrete (AAC) materials, where a cement gains its strength and other properties via a chemical reaction between a source of alkali (soluble base activator) and aluminate-rich materials.

Features and benefits:

• Reduced CO2 emissions – a carbon reduction of up to 90% is achievable.

• Reduced heat evolution.

• Has all of the structural characteristics of traditional concrete.

• Sustainable.

• No need to invest in new equipment or working practices.

• Reduced chloride diffusion coefficient.

• Enhanced chemical resistance to sulphate and acid, with improved resistance to chloride ingress.

• Enhanced fire resistance.

• Reduced shrinkage ensures a reduction the number of joints overall in a structure is possible.

• Provides a potential reduction in the crack-control steel required for a project.

• Safe and easy to handle.

• Lighter in appearance to conventional concrete.

• Manufactured in accordance with PAS 8820: 2016.

Applications:

• Capping beams.

• Retaining walls.

• Piling.

• Strip foundations.

• Reinforced foundations.

• Raft slabs.

• Walls.

• Mass concrete fill.

• Over-site applications.

• Floors.

• Pre-cast elements.

Should not be exposed to rain water or moisture.
