✽ Cold-activated Clay Cement CCC®
A patented and truly disruptive technology platform
All Materrup cements integrate the patented CCC® technology (Cold-Activated Clay Cement) developed by Materrup, an industrial innovation designed to durably transform the construction industry.
A process with no kiln, no calcination, no emissions.
CCC® technology is based on a proprietary mechano-chemical cold activation process for clay. Unlike traditional cement processes or calcined clay technologies, this process operates without firing, without calcination and without thermal flash.
Waste valorisation and resource preservation
This approach valorises raw, local clays — often considered waste — by transforming them into high-performing, reliable cements suited for structural concrete applications.
Raw material flexibility: kaolinitic, illitic, muscovitic and mixed clay waste — with no minimum or maximum composition limit.
Protected by more than 100 international patents
Protected by more than 100 international patents, CCC® technology represents a stable and proven industrial alternative to conventional cements. It is already industrialised and validated across more than 500 construction projects, demonstrating its robustness, reproducibility and reliability under real conditions.
Cold mechano-chemical activation
a unique, lean and proven process
reinvents cement and clay activation by eliminating thermal treatment. CCC® technology activates clay at ambient temperature through a mechano-chemical process, without calcination. Clay is made reactive by combining grinding (fine and controlled mechano-chemical activation) with the action of an organic agent to form a hybrid organo-mineral material.
Mechanical activation places non-calcined clay minerals within the broad field of "natural pozzolanic materials" activated by physical means: controlled grinding transfers energy to the material, promotes delamination of layered structures and reduces particle size, induces structural disorder and lattice defects — thereby increasing the effective reactive surface area. In an alkaline environment, these transformations facilitate the dissolution of Si and Al species, contributing to the pozzolanic reaction.
The introduction of an organic agent acts at particle interfaces to enhance surface reactivity and promote the formation of mineral–organic–mineral complexes.
This mechano-organic coupling maximises activation efficiency within an optimised processing window and confers on the clay a reactivity equivalent to calcined clay — without any thermal step. .

A technology already proven in the field
Our solutions have been tested and validated on over 1000 construction sites, demonstrating their robustness, reproducibility, and reliability under real conditions. Because what matters on site is being able to strike the formwork after 16 hours, we have designed our cements and mortars to match construction schedules, with no compromise on performance or implementation.
Uncompromising performance.
Our products offer certified mechanical and environmental performance, with full transparency. Designed for real-world conditions, they integrate seamlessly into your existing practices, with no constraints or adaptations required Browse the documentation
We will not decarbonise concrete by incrementally optimising what already exists. We need to reinvent the material itself.
We made that radical choice: activating clay cold, without kilns, without calcination, without fossil fuels. Using what is discarded on construction sites and in quarries. What others call waste, we call cement.
Over 100 patents. Over 1,000 construction sites. A competitive price. Not a laboratory promise — a robust industrial and technological reality.
This is not an improvement.
It is a revolution for an entire industry.
From your waste to your cement: take control! Produce without intermediaries. Without dependency.
