Ruben Snellings

Ruben Snellings is a Professor at the KU Leuven, affiliated with the Institute for Sustainable Metals and Minerals and the Division of Geology. His research focuses on sustainable cementitious materials, mineral carbonation, and valorization of industrial by-products in construction. He actively contributes to RILEM technical committees, including TC 309-MCP and TC 267-TRM, establishing terminology and testing protocols for carbonation-based construction products.
