Cemfree : low carbon cement-free binder

Cemfree technology is a revolutionary alternative to Ordinary Portland Cement (OPC)

Cemfree cement-free activating technology is a proprietary Alkali-Activated Cementitious Material (AACM) that activates pozzolanic materials to create concrete that performs similarly to Ordinary Portland Cement (OPC). By utilising these pozzolanic materials, Cemfree technology provides the desired strength and durability required for various construction applications, making it a versatile and effective alternative to traditional cement.

The materials react with Cemfree Binder to form a solid mass comparable to OPC, making it an ideal green, environmentally friendly alternative. Replacing 100% of the OPC with Cemfree results in an embodied CO2 reduction of up to 85% compared to OPC-based concretes. This makes it a sustainable choice, utilising traditional substitute cementitious materials (SCMs) and alternative by-products.

We offer flexible solutions to meet your needs, including liquid or powder activators that can be added to onsite materials to produce cement-free concrete or provide an all-in-one bespoke binder. Cemfree materials are available in large bulk or small bagging to ensure seamless integration with your batching infrastructure. Our tailored technology allows us to modify performance and cost to suit your production and product requirements.

WE help reduce concrete’s carbon emissions with game-changing technology and dedicated R&D

Reduces the embodied carbon

The innovative concrete formulation significantly reduces the embodied carbon associated with its production, thereby supporting the circular economy by minimising the need for raw materials and limiting waste sent to landfill.

Reduction in water footprint

It achieves a remarkable reduction in the water footprint, ranging from 40 to 60%, and features a low heat of hydration, which enhances its stability. This concrete also boasts improved chemical resistance and performance in aggressive ground conditions, along with excellent flow and self-compacting characteristics due to its low water-to-binder ratio.

Increased aesthetic appeal

Cemfree binders offer an increased aesthetic appeal, presenting a whiter appearance compared to ordinary Portland cement (OPC).

Mixing instructions
