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 most consumed resourceA mass balance also called a material balance is an application of conservation of mass to the analysis of physical systems By accounting for material entering and leaving a system mass flows can be identified which might have been unknown or difficult to measure without this technique The exact conservation law used in the analysis of the system depends on the context of the problem
