Cemfree is a proprietary Alkali-Activated Cementitious Material (AACM) that activates pozzolanic materials such as Ground Granulated Blast-furnace Slag (GGBS) and Pulverised Fly Ash (PFA) to create a Cemfree Binder which can replace a variety of cement types to create Cemfree Concrete. The reaction between GGBS and Cemfree Binder forms a solid material comparable to OPC, making it an ideal replacement.

Replacing 100% of the OPC with a Cemfree binder results in an embodied CO2 that is up to 80% lower than OPC-based concretes. Similar to OPC, Cemfree-based binder is a safe, easy to handle, dry powder product that allows the use of existing plant infrastructure.

Cemfree Applications

The use of Cemfree materials are becoming increasingly common in a wide variety of structures including capping beams, retaining walls, piling, blinding, strip foundations, raft slabs, walls, mass fill, oversites, floors and pre-cast elements.

Cemfree Benefits & Characteristics

  • Achieves CO2 savings of up to 88%
  • Comparable strengths achieved with conventional Concrete
  • Low level of heat during curing, causing improved chemical reaction
  • Tailored for various mechanical and engineering properties
  • Batched delivered in the same way as OPC based Concrete
