Is it possible that a structure absorb co2 from surrounding environment and use it for attainting strength

As we see co2 is freely available in the environment so can we use it in construction in order to reduce its concentration in environment 

In the olden days slaked lime (calcium hydroxide) was used as white wash. In time this absorbs COfrom air becoming calcium carbonate. 

So why not use lime in construction to absorb CO?

How do we get CaO? From limestone by heating, which releases CO

Back to the pavilion? New research shows that if the lime is added to sea water, it absorbs twice the amount of CO. It becomes net carbon negative. More work is needed.
