Idaho Researchers Develop Sustainable "SweetCrete" Concrete
Idaho State University researchers have created an innovative, eco-friendly concrete blend called SweetCrete, aimed at reducing landfill waste and lowering the carbon footprint associated with traditional construction materials.
Key highlights:
- SweetCrete replaces 30% of traditional cement with precipitated calcium carbonate (PCC), a byproduct of the sugar beet industry, and uses 100% upcycled crushed concrete as aggregate.
- This new blend can cut costs by 15–20% per cubic yard compared to traditional concrete, thanks to the use of local waste materials and reduced expenses from raw materials.
- The research team, led by Professor Mustafa Mashal and principal investigator Dr. Tadesse Wolkjerra, is aiming to further refine SweetCrete using advanced AI and machine learning to optimize mix designs for durability and performance across different applications.
- The team plans to begin field testing soon, with goals to ensure SweetCrete meets industry benchmarks for strength and durability—including surviving Idaho’s harsh winters.
- If successful, SweetCrete could be used widely both in Idaho and internationally, supporting sustainable construction practices and a circular economy.
ISU researchers emphasize that their approach not only checks environmental goals but is also focused on practicality and cost-effectiveness for the construction industry.
