Cement - Wikipedia
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. 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.Concrete is the most widely used material in existence and is

problem. It is recommended that low alkali Portland cement be used to reduce the chances of efflorescence occurring. Low alkali Portland cement has 0.6% alkali or less, by weight in the cement (2, 3). Another culprit is, of course, the clay brick itself. The natural clays used in the manufacture of brick often contain soluble alkali sulfates.
