Materials & Embodied Carbon Leaders’ Alliance’s Post

Interested in sustainability and zero-net carbon construction projects? Steel is a critical path material that impacts both in major way.

This is a valuable resource for industry professionals seeking guidance on specifying low carbon concrete in their projects or aiming to gain deeper insights into the current state of concrete, cement, and carbon.

The National Ready Mixed Concrete Association (NRMCA) has taken a significant step forward in helping the building industry to reduce the embodied carbon of the built environment. It has developed a Concrete Carbon Calculator that provides a simple and efficient way for ready-mix suppliers and contractors to calculate the environmental impacts of concrete used in their building projects. First launched in 2024, the tool has quickly become foundational in advocating for sustainable benefits and capabilities of concrete materials. It also helps to assess the impact of lower-carbon alternatives and demonstrates compliance with a pre-determined carbon budget on individual projects. Learn more here: https://bityl.co/Of0V

Construction company C-Crete Technologies claimed that the concrete is an environmentally friendly alternative to conventional Portland cement and emits close to zero CO₂ during its manufacture and can also absorb CO₂ from the atmosphere over time. C-Crete Technologies said that the concrete had great flowability, was pumped and achieved a loading strength of over 5,000 pounds per square inch, greater than the ASTM standard of about 4,000 psi for most residential, commercial and infrastructure concrete applications. “I’m seeing exciting advancements, but few are ready to scale into production the way C-Crete can now. No-cement, and low-carbon concrete isn’t just a pipe dream. It is real, it is now, and it works. This project proves it’s possible, today.” C-Crete Technologies says that Portland cement is responsible for around 7 percent of total CO2 emissions worldwide. If used instead, the new material can help substantially reduce the environmental impact of the construction industry. Each ton of C-Crete binder that replaces Portland cement prevents approximately 1 ton of CO2 emissions. Furthermore, the product utilizes a suite of natural minerals and industrial by-products, ensuring an abundant feedstock. The company says that it looks forward to collaborating with architects, designers, general contractors, ready-mix companies, building owners and decision-makers for infrastructure projects to accelerate the adoption of its sustainable concrete. https://lnkd.in/dMfmPNyG #Concrete #Environment

Grab (that is to say 'download') the latest issue of Concrete NZ Readymix News!   James Mackechnie, South Island Technical Manager/Plant Engineer at Allied Concrete, has contributed an insightful article based on his award-winning conference paper - "Sand Quality Contribution in Producing Low Carbon Concrete."   The article delves into the potential for significant cement savings and, consequently, reduced carbon emissions, by emphasizing the importance of investing in better control of fine aggregate quality. To access the full details, download Readymix News - https://lnkd.in/g7W5zUai   James’ efforts haven’t gone unnoticed. His paper was selected for the Sandy Cormack Best Paper Award, a prestigious honour recognizing its relevance to the New Zealand concrete industry's decarbonization journey.   Established in 1998 in memory of H.W. (Sandy) Cormack, this award highlights topics crucial to the development of the concrete industry in New Zealand.   The judges were impressed by the written paper's structure, clarity, and completeness, as well as James' ability to connect with and engage the audience. The recognition is a testament to the significance and relevance of his work in advancing concrete knowledge.   #concretenz #buildingresilience #readymixnews #concrete #sustainableconcrete #netzerocarbon #concretedesign #concreteconstruction #concretemix #concretesand #concreteaggregate #aggregate #sand #sandycormackaward #sustainability

C-Crete Technologies achieves a groundbreaking milestone with the deployment of the world’s first basalt-based concrete, marking a significant step towards eco-conscious construction materials. The recent pour in Seattle utilizes basalt as the primary binder, entirely replacing Portland cement and contributing to a total of 140 t of C-Crete’s cement-free concretes. Basalt's abundance and non-carbonate nature make it an environmentally friendly alternative to traditional cement, significantly reducing CO2 emissions associated with production. Additionally, the curing process of basalt-based concrete captures CO2 from the atmosphere, further enhancing its eco-friendly profile. With compressive strength exceeding 5000 psi and meeting ASTM International standards, C-Crete's basalt-based concrete demonstrates pumpability, workability, and surface finish akin to conventional concrete. This innovative solution paves the way for widespread adoption, offering a cost-parity option for sustainable construction practices. . . .
