Is There a Way to Reduce Omissions in Concrete?

Carbon is part of the process of making concrete, so how can we mitigate it? Companies at energy intensive industries are replacing fossil fuel with renewable fuels. The other 60 % or so is that chemical process called calcination. How you can deal with that is to capture the carbon, okside. If you pump some of that c o to back into concrete when you're mixing it with cement, it actually makes the concrete harder. Or if you have harder concrete, then you can use less of it to build stronger buildings.
