I recently read Construction Physics' post on concrete use:

and I consider it to be required reading for people outside of the field on the topic of concrete emissions. Globally, concrete production emits like crazy but this is largely a product of scale; other building materials emit far more GhGs by mass and volume but are used in much smaller quantities than concrete.

I'm all for a broad package of carbon taxes to both reduce growth and force the development of political and financial solutions for a low-growth, steady-state or degrowth economy but don't be misled into thinking the end result is a smaller share of concrete as a building material. More likely, carbon taxes will reduce the proportions of plastics, steel, aluminum and glass in construction in favour of more concrete.
