In the search for sustainable building solutions, concrete floor slabs are a key challenge due to their high carbon footprint. Harnessing digital fabrication tools, a research team has explored a novel 3D printed plastic formwork to produce optimised ribbed floor slabs in an efficient manner. The new approach uses 40 percent less concrete, while offering the same structural performance. Credit: ETH Zürich #3dprinting #research #engineering | Wevolver.com

Hey Glenn Highway friends, we're over halfway through the second full bridge closure at the Knik River 🎉Thank you all for your patience while we rehabilitate these bridges! When the bridge reopens you might feel like the concrete seems a bit "unfinished." Don’t worry, that’s temporary! Here’s what’s going on: ✅ This week we’re pouring the final approach slabs (yay!) 🕐 After that, the concrete needs to cure for 28 days before we can apply the final overlay of a mix of concrete and polyester res
