High amounts of carbon emissions are emitted during the production of concrete, which is the most used substance in the world after water. The CO2-free version of cement is coming.
8% of the world's carbon emissions are emitted during concrete production. Until recently, we did not have a solution to this problem because cement production requires a very high heat source and releases CO2 as a chemical reaction. The chemical reaction accounts for `` of the emission.
Therefore, even if we obtain all the heat from renewable energy, the emission of ` continues.
Naturally, a team of scientists, aware of this situation, has been experimenting with over 2000 reactions since 2010, trying to obtain a similar concrete. As a result, they managed to produce a concrete that can be poured from a concrete mixer as fluidly as concrete, freezes in half an hour and withstands high pressure.
The next version is that over time, the concrete will absorb and trap carbon dioxide from the air. And this extra reaction will make it more durable. In this case, the massive concrete pouring will become a carbon dioxide absorber from a massive source of carbon dioxide emissions.
Last summer, the company poured 60 tons of concrete for the first time into the foundation and curtain walls of an old building during its renovation.
The process was completely normal, except that instead of cement, a binding agent prepared by C-Crete was used.
