Building Cities from Cities: Recycled Cement Paste at Holcim
with expert Alfonso Paradinas Aguilera, CMO of the Holcim Group Sustainable Concrete Durability: How Recycled Cement Paste Replaces Clinker Cement accounts for roughly 8% of global CO2 emissions. Any serious conversation about sustainable concrete durability has to address how the industry cuts clinker content without compromising load-bearing capacity or service life. Alfonso Paradinas Aguilera, Global […]
Inspecting Bridges with Particles from Space
Wie Muonen, KI und 3D-Scans Spannkabel, Korrosion und Hohlstellen in Betonbrücken sichtbar machen. Summary Muon technology is increasingly being explored for concrete inspection and bridge inspection. By analysing naturally occurring cosmic particles, internal structures of concrete can be visualized non-destructively, including prestressing tendons, voids, material variations and highly congested reinforcement arrangements. In this episode of Concretely, […]
Concrete Inspection: GPR, Ultrasound & AI
How modern Concrete Inspection like GPR, Ultrasound & AI is used to inspect structures efficiently and enables databased maintenance. with expert Koichi Oba, CEO of Proceq (Tectus Group) Summary Aging infrastructure, limited inspection resources and increasing data requirements are key challenges in modern concrete inspection. In this episode of Concretely, Johannes Lohner speaks with Dr. […]
Can Satellites Predict Bridge Collapses?
Millimeter Precise Monitoring of Bridges With InSAR InSAR (Interferometric Synthetic Aperture Radar) is emerging as one of the most powerful technologies for modern infrastructure maintenance. As explained by Alois Vorwagner from the Austrian Institute of Technology (AIT), InSAR enables—for the first time—cost-efficient, large-scale and millimeter-accurate monitoring of bridges, roads and railways directly from space. This […]
