Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Cement is the most widely used material in existence and is only behind water as the planet''s mostconsumed resource.
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.
