Abstract :
[en] Brick waste is produced in large quantities by the civil engineering sector without any real valorization. A way of valorization of this material consists of an incorporation of the brick fines in cement by substituting clinker to produce an alternative hydraulic binder. Blended cement based on brick fines would present the advantage to enhance cement environmental impact by reducing CO2 emission. Therefore, the aim of this paper is to study the impact of brick fines incorporation with three different particle sizes on fresh and hardened cement paste properties. Potential pozzolanic activity of the three brick fines was investigated as well as their impact on the microstructure and strength of these binders on cement paste samples. The results showed that it was possible to make blended cement based on brick fines. Incorporation rates up to 20% gave good performance compared to the reference cement. The incorporation of brick particle size close to a cement powder seemed the most appropriate. In addition, the brick fines contributed hydraulic performance by their pozzolanic activity.
