Cemfree – The Product

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.
