Researchers at Mepco Schlenk Engineering College have developed a sustainable concrete formula that actively pulls carbon dioxide from the air while outperforming standard building materials in structural durability.
Key Highlights of the "ZB5" Mix
- Natural Ingredients: The concrete replaces fine gravel with porous zeolite (50%) and standard cement with bamboo biochar (1%), creating microscopic traps for atmospheric gas.
- Increased Durability: Compared to conventional concrete, the formulation boosted split tensile strength by 15% and compressive strength by 7.5%.
- Active Carbon Absorption: In laboratory tests, the material captured 1.2 grams of CO₂ per day, with gas penetrating 15 mm deep over a single week.
Designed for high-emission areas like highway pavements, barrier walls, and sewer systems, this biochar-infused concrete turns everyday infrastructure into an active tool for environmental cleanup.
