🌍 Breakthrough in Cement’s Carbon Capture: A Path to Sustainable Construction! 🏗️ Exciting developments are on the horizon for the construction industry! Researchers from Massachusetts Institute of Technology and Chiba University have discovered new methods that allow cement-based materials to capture CO₂ from the atmosphere, potentially revolutionising the future of climate change. 🔬 According to Admir Masic from MIT, "This research highlights how we can use cement, one of the most commonly used materials on Earth, to tackle climate change. It's exciting to see how simple additives like sodium bicarbonate can significantly enhance carbon capture while maintaining concrete’s mechanical strength." Meanwhile, Takahiro Ohkubo from Chiba University added, "Our work reveals that water transport and structural changes in cement play a crucial role in how well it absorbs CO₂. This new understanding could lead to more efficient carbon capture materials for the construction industry." This could be a game-changer for a more sustainable future in construction! 🌱 Special thanks to Portland Cement Association, CONCRETE ADVANCEMENT FOUNDATION and The University of Tokyo for their contributions and comments. #Sustainability #CarbonCapture #Construction #Cement #ClimateChange #Research #Innovation #GreenBuilding #CO2 #Engineering Feel free to share your thoughts on this incredible innovation: https://lnkd.in/ez_9JEpK

It seems as though Researchers at Idaho State University’s Department of Civil and Environmental Engineering have made significant strides in sustainable construction materials. In a recent study, they explored the use of precipitated calcium carbonate (PCC), a byproduct from sugar processing, as a substitute for cement in concrete. PCC, chemically identical to natural limestone, proved to maintain concrete strength similar to traditional methods. The research team found that up to 30% of cement in concrete can be replaced with PCC while still meeting American Society for Testing and Materials standards. With conventional concrete production being a significant emitter of carbon, this alternative presents a circular and cost-effective solution. While the initial results are promising, the researchers plan to conduct further tests to assess the concrete's durability under various conditions. This includes resistance to freeze-thaw cycles, surface hardness, and real-world conditions. Could this discovery have the potential to revolutionise the concrete industry, which contributes to 8% of global CO2 emissions? #energytransition #climatechange #innovation #construction

Geopolymer concrete is a concrete with geopolymer as the binder rather than cement. This innovation has been studied by many researchers using different precursors and activators. However, the fundamentals need to be understood before a visible breakthrough in this research field.

🎙 Materials and Durability - DTU Sustain hosted a section seminar last week, where we had the honor of a visit from Tina Vejrum, who is Senior Technical Director at COWI, President of IABSE - International Association for Bridge and Structural Engineering, and Affiliated Professor at DTU - Technical University of Denmark.   We were truly impressed when hearing about the different large, international bridge projects Tina had been involved in, and at the same time it was a strong incitement for us to continue our work of developing more sustainable construction materials.🌉 👏 We are happy for the collaboration with COWI and COWIfonden, e.g. on the two PhD projects: ▪ Anders Hedegaard Jensen's project attempts to relieve the strain on a natural resource. Sand, in a quality that can be used in concrete, is globally seeing increased shortages in different regions. At the same time, we are producing ashes from biomass combustion, which is currently under-utilized. If we can use bottom ash from the combustion of wood to replace sand in concrete, we can potentially solve environmental problems simultaneously. Initial results are very promising! ▪ Marvin Glißner deals with concrete, the most used construction material globally and significantly contributes to CO2 emissions. The associated cement production is mainly responsible for that, accounting for 8-10% of global CO2 emissions. Alternatives to traditional Portland cement are crucial to reducing environmental impact. This project explores cement-free concrete, which can reduce CO2 emissions by up to 90%. By using waste products and low-CO2 materials such as local calcined clay as binders, the project aims to ensure safe, long-term structural integrity. Through experimental and numerical investigation, the project seeks to show reliable predictions for the adoption of more eco-friendly concrete.

Proud to announce the publication of an awareness piece around green premiums. This should be a wake up call for all real estate developers and financiers to start using low carbon materials for construction. In some cases there is also evidence of developers reducing upto 40% of their embodied carbon with market-ready solutions at little to no extra cost! #CREDAI #NAREDCO #GCCA Adoption of low carbon materials will encourage manufacturers to make further investments and continue the virtuous cycle of cost reduction
