There are several things that you can do. 0) Build using appropriate materials/design/construction. It's mostly a solved problem, it just takes wanting to spend enough money to do the process right. 1) Use epoxy coated rebar. It's commonly used in places where there's a large risk of cracking and rebar corrosion (e.g. roadways) 2) Use prestressing/posttensioning to put an overall compressive force on the concrete to prevent cracking.
