Almond Activated Geopolymer Cement

Abstract

Researchers at the University of California, Davis have developed a sustainable alternative to Portland cement by utilizing alkali-activated binders (AAB) with biomass ash, significantly reducing greenhouse gas emissions.

Full Description

The technology focuses on creating geopolymer concrete using alkali-activated binders (AAB) mixed with biomass ashes, such as almond shell ash, as a climate-friendly alternative to traditional chemical activators. This approach not only aims to reduce the carbon footprint associated with concrete production, but also leverages agricultural waste products, thereby offering a dual benefit of environmental sustainability and resource efficiency.

Applications

• In general, wherever Portland cement is used in projects requiring high strength. 
• Construction materials for infrastructure and buildings. 
• Low-carbon, sustainable urban development projects. 
• Green building certifications and eco-labeling products. 
• Research and development in sustainable construction technologies.

Features/Benefits

• Significant reduction in greenhouse gas emissions compared to traditional Portland cement. 
• Utilization of biomass ash reduces the need for caustic and costly chemical activators. 
• High durability and comparable mechanical properties to Portland cement concrete. 
• Contributes to waste valorization by repurposing biomass residues as construction materials. 
• Potential for cost reduction in concrete production through the use of readily available biomass ash.
