Breakthrough cementless ready-mixed concrete is fundamentally CO2 free and absorbs CO2 over time, helping to drive the construction industry to zero emissions. C-Crete
Technologies' innovative cement-free concrete is proudly introducing an "industry-first" concrete to the public at the construction site of a commercial building in Seattle. This new cement is a sustainable alternative to traditional Portland cement, produces virtually no carbon dioxide in its manufacture, and also absorbs carbon dioxide from the air over time. The production and use of
Portland cement account for about 7% of global carbon dioxide emissions. The use of this new material can greatly reduce the environmental impact of the construction industry. Each ton of C-Crete binder that replaces Portland cement can reduce carbon dioxide emissions by about 1 ton. In addition, the product uses a series of natural minerals and industrial by-products to ensure sufficient raw materials for production.
Located at 7200 Woodlawn Avenue in Seattle, the project used about 60 tons of cement-free concrete, mainly for the foundation and shear wall. The project is an adaptive reuse development of a 120-year-old brick building that originally used concrete as part of a seismic retrofit.
The new cementless concrete has excellent flowability and is pumped with a load strength in excess of 5,000 psi, which is above the ASTM standard of about 4,000 psi for most residential, commercial, and infrastructure-specific applications. The new concrete also meets other key industry standards, has excellent durability (such as resistance to freeze-thaw cycles, alkali-silica reaction, and chloride and acid penetration), and is compatible with traditional concrete mixtures, allowing it to be easily incorporated into existing building practices.
"We are thrilled to be able to launch our cement-free concrete.". The new cement is a game-changer in sustainable construction. "Dr. Rouzbeh Savary, founder and president of C-Crete, said.". "Our binders are a direct replacement for Portland cement, which significantly reduces carbon emissions.". Our products meet industry standards, and the cost of our products is comparable to traditional concrete. In view of this, the product opens a new era in the construction industry. "
C-Crete's cement-free concrete for the project is produced by Heidelberg Materials, a global building materials and ready-mix concrete company.".
The Seattle building is owned by Donald Davies, who is also the chairman of Building Transparency. Building Transparency is a non-profit organization dedicated to enabling the construction industry to address the role of embodied carbon in climate change. "As a developer, a building structural engineer with a 33-year career and a leader in low-carbon construction, I know that there are a variety of low-carbon concretes under discussion," Davies & nbsp; said. "。 "I can feel the exciting progress, but few of them can be mass-produced like C-Crete is now.". Cement-free low-carbon concrete is not a daydream. It's real, it's available now, and it's actually available. This construction project proves that it is possible now. "
With the success of its concrete in Seattle, C-Crete is poised to change the landscape of construction on a national and even global scale.". The company looks forward to working with architects, designers, general contractors, ready-mix companies, building owners, and infrastructure project decision-makers to accelerate the adoption and use of its sustainable concrete.
