About the conference
The ERICA and CASH II Final Conference was held in an online format from January 25 to 27, 2021. At this event, the ERICA and CASH II projects were be presented along with invited and contributed talks.
The organizers were very pleased to welcome 127 registered participants from 21 different countries.
Inorganic hydrates such as calcium-silicate-hydrate, abbreviated C-S-H, are “wonder” materials exceedingly rich in terms of potential applications that can be produced in almost any shape or form, cheaply and in large quantities right across the world from local and sustainable resources. C-S-H is the “glue” of cement, itself the glue of concrete, material with enormous economic impact. But C-S-H and other hydrates are also used as a filler in paper and in polymer composites, as dental filling materials, for waste water treatment in fertilizers and as insulation and encasement materials including for nuclear waste.
C-S-H is the main phase controlling the performance of cement-based materials. These materials are so widely used that their production is the leading industrial source of greenhouse gases, contributing about 8% of global CO2 emissions despite very low emissions per kg. Engineering C-S-H growth for faster strength development and for improved performance, such as water transport that affects C-S-H durability, is key to further lowering the CO2 impact of construction.
The conference is co-sponsored by
ERICA, a project funded by the European Union under the Horizon 2020 – Marie Skłodowska-Curie – Innovative Training Network programme, is an innovative, five-nation project straddling materials science and engineering, physics and chemistry in diverse areas of experimentation and computational modelling.
The overarching aim of the ERICA project is to understand how to engineer hydrates at the nanoscale and to enable improved engineering applications. Read more…
About CASH II
Another way to reduce CO2 emissions is to partially replace Portland cement by Supplementary Cementitious Materials (SCMs) such as blast furnace slag, fly ash, silica fume or calcined clays. However, these SCMs cause changes in C-S-H composition.
CASH II is a Swiss-Danish research project investigating the effect of aluminum, potassium and sodium on the structure and solubility of C-S-H, using innovative experimental methods and computational modelling. Read more…

The final program is available here for your reference. The scientific program consisted of 11 invited and 36 contributed talks.
The virtual conference was be held in Zoom and Gather.Town. Presentations as well as short Q&A sessions following the presentations were be handled in Zoom. Participants were kindly invited to also join interactive discussion sessions in a “Town Hall” meeting in Gather.Town at the end of each contributed session.
