Concrete is the most widely used manufacturing material on the planet. The key strengthening ingredient in concrete is cement, whose production expends considerable amount of energy and contributes to 5-10% of CO2 emissions worldwide, making concrete the biggest climate change culprit outside of transportation and electricity-generation. C-Crete Technologies has engineered an innovative cement which is stronger than typical cement, while reducing both energy consumption and CO2 emitted during the cement manufacturing process.
