Low Carbon Concrete and Its Advantages - The Constructor

Feb 11, 2019  Low Carbon Concrete and Its Advantages. Low carbon concrete has attracted significant attention due to the amount of CO2 that traditional concrete emits. It is demonstrated that, cement have biggest contribution in CO2 emission by 75% of total CO2 emits by concrete, and aggregate is the next great contributor by less than 20%.

Low carbon concrete

Low embodied carbon constituents. Concrete is a low carbon material. Its versatility, performance and local availability has resulted in it being the second most consumed material globally (after water). The potential to reduce global carbon emissions, by reducing the embodied carbon of such a widely used material are not in doubt.

Low Carbon Concrete - Lowering the Carbon Footprint of Eco ...

Mar 04, 2020  The benefits of carbon storage in concrete are twofold – on one hand CO2 is being introduced to the mix, so once the concrete hardens it is sequestered forever, and the other benefit is that adding carbon to concrete actually makes it stronger. That means between 5% and 7% less cement is needed to achieve the same compression strength.
