 · However, by adding the carbon dioxide, the strength of the reducedbinder batch improved to be within 4% of the standard mix at 28 days. This suggests that a CO 2 injection in conjunction with a binder reduction on the order of 7% can result in concrete without compromised performance. The binder reduction in the airentrained batch led to an ...

Feb 18, 2021 · Concrete, the most widely used material in the world, has come under scrutiny recently for its large carbon footprint. But concrete also has a natural ability to soak up carbon dioxide from the air over its lifetime, albeit very slowly.. A new concrete recipe developed by Purdue University researchers can double this carbonabsorbing speed.
