This new concrete is stronger and pulls CO2 from the air

Researchers have created a concrete mixture that is both stronger and capable of absorbing carbon dioxide. The best formula, combining zeolite with bamboo biochar, boosted compressive strength by 7.48% and tensile strength by 15% compared with conventional concrete. It also captured about 1.2 grams of CO₂ per day in laboratory testing.

This new concrete is stronger and pulls CO2 from the air. Com Engineers have created a new type of concrete that is stronger than conventional concrete while also capturing carbon dioxide from the atmosphere. The findings, reported in Carbon Research, suggest that adding carefully selected natural materials could give concrete a second role beyond construction by helping remove CO 2 from the surrounding air.

Researchers at Mepco Schlenk Engineering College in India developed the mixture as a possible way to make construction materials more sustainable. Their approach targets a major environmental challenge: rising atmospheric CO 2 levels driven in large part by fossil fuel use and cement production. The team, led by Srinivasan Revathi, focused on two natural additives.
