Carbon-Eating Cement
|
TecEco have developed cement technologies able to transform city streets and buildings into carbon "sinks", rather than sources.
By blending magnesium oxide and conventional cements, this environment-friendly cement uses a lower heating temperature during manufacturing, so less fossil fuels are used. Once it's in porous concrete form, eco-cement needs carbon dioxide to harden and set. Therefore, it absorbs large quantities of the greenhouse gas that concrete is partially responsible for, contributing about 10% of global CO2 emissions. Picture is the world's first eco-cement porous pavement in Tasmania. |
