Strength of Concrete vs Grades of Cement

There are cases when the cements of certain grades give more than prescribed strength at 7 days and thereafter a very little gain in their strength is observed till 28 days and in some cases the strength does not reach the level as per the grade. There are also cases, where a 43 grade cement gives 28 day strength matching with 53 grade.
