ABSTRACT: Concrete technology has been practice in the construction industry for over millennia by using cement, sand and aggregate. The compressive strength of about 30-50N/mm2 was the maximum strength range achievable which is the limit capture by various codes of practice with the durability estimated on the basis of thickness of concrete cover. In today’s technology, the compressive strength of up to 170N/mm2 is achievable with the durability calculated on the basis to time for deterioration. Concrete section could be reduced by more than 1/3 of the conventional thickness of structural components.
