Nanotechnology designed to speed up the hardening of concrete

April 26, 2017

Researchers at Tecnalia and the ICMCB-CNRS have recently published the article "Ultra-Fast Supercritical Hydrothermal Synthesis of Tobermorite under Thermodynamically Metastable Conditions" in the prestigious scientific journal Angewandte Chemie.

The article proposes an ultrarapid synthesis of nano-tobermorite, a nanoparticle used to speed up the hardening of concrete and regarded as a high-added value addition. The possibility of producing tobermorite nanofibres in water in supercritical conditions (400 ?C and 235 bar) has been demonstrated, when above 200 ?C it had been thought to be impossible. What is more, the outcome is a product of a higher quality made possible by the fact that a piece of non-traditional equipment, which allows the conditions and reaction times to be thoroughly monitored, has been developed.

The technology developed is, according to the researchers involved, "The Advanced Manufacturing Technique" for producing nanoparticles; it is and will be very important for any SME in the field of nanotechnology since it enables two aspects that are intrinsic to industrial production to be achieved: quantity and quality. Firstly, tobermorite nanoparticles can be synthesised within the space of 10 seconds as opposed to several days taken by traditional synthesis methods. Secondly, the synthesis method using supercritical fluids produces better replicas of natural tobermorite, in other words, it allows more perfect nanoparticles to be produced.

Furthermore, the journal has designated the work as a Very Important Paper, and frontispiece, in other words, it is regarded as being within a 5th percentile and a showcase of the publication given that it has been selected as the back cover. This work is the outcome of collaboration between Tecnalia, the UPV/EHU-University of the Basque Country, the University of Bordeaux and the ICMCB-CNRS within the framework of the euro-regional campus of excellence Euskampus-IDEX of Bordeaux.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies.
