Digital tools to build a sustainable future

Optimizing heat curing and binder hydration

In addition to the mix design optimization, optimization of the production process can lead to a significant reduction of the carbon footprint of the precast industry. In this article, the authors demonstrate how digital solutions can be used to achieve this goal. This is achieved by modeling the binder hydration. Thanks to numerical analysis, the temperature evolution, the hydration rate can be computed for different scenarios, including heat treatment. Which allows the identification and selection of the most efficient solution with respect to environmental constraints.
