Now, billions of tons of concrete are poured each year for variety of the projects from underground structures to skyscrapers.
Such rapid strength gain makes early formwork removal possible, shortens the construction time and puts structures into service early.
Many concrete structures are out of service prematurely due to the poor anti-corrosion ability of concrete challenged by severely aggressive exposure conditions.
