  1. Cement

    A cement is a binder, a chemical 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 (aggregate) 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 behind only water as the planet's most-consumed resource.Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and safe from chemical attack. This allows setting in wet conditions or under water and further protects the hardened material from chemical attack. The chemical process for hydraulic cement was found by ancient Romans who used volcanic ash (pozzolana) with added lime (calcium oxide). Non-hydraulic cement (less common) does not set in wet conditions or under water. Rather, it sets as it dries and reacts with carbon dioxide in the air. It is resistant to attack by chemicals after setting. The word "cement" can be traced back to the Ancient Roman term opus caementicium, used to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick supplements that were added to the burnt lime, to obtain a hydraulic binder, were later referred to as cementum, cimentum, cäment, and cement. In modern times, organic polymers are sometimes used as cements in concrete. World production is about four billion tonnes per year, of which about half is made in China. If the cement industry were a country, it would be the third largest carbon dioxide emitter in the world with up to 2.8 billion tonnes, surpassed only by China and the United States. The initial calcination reaction in the production of cement is responsible for about 4% of global CO2 emissions. The overall process is responsible for about 8% of global CO2 emissions, as the cement kiln in which the reaction occurs is typically fired by coal or petroleum coke because a luminous flame is required to heat the kiln by radiant heat transfer. As a result, the production of cement is a major contributor to climate change.


  1. cement

    Cement is a powdery substance made with calcined lime and clay, used as a binder in building materials such as concrete, mortar, and stucco. It hardens when mixed with water due to a chemical reaction called hydration, resulting in a stone-like, durable material. Cement is essential in most construction projects as it provides strength and stability to structures.

  10. Etymology: [OF. cement, ciment, F. ciment, fr. L. caementum a rough, unhewn stone, pieces or chips of marble, from which mortar was made, contr. fr. caedimentum, fr. caedere to cut, prob. akin to scindere to cleave, and to E. shed, v. t.]


  1. Cement

    In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. The word "cement" traces to the Romans, who used the term opus caementicium to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick additives that were added to the burnt lime to obtain a hydraulic binder were later referred to as cementum, cimentum, cäment, and cement. Cements used in construction can be characterized as being either hydraulic or non-hydraulic. Hydraulic cements harden because of hydration, a chemical reaction between the anhydrous cement powder and water. Thus, they can harden underwater or when constantly exposed to wet weather. The chemical reaction results in hydrates that are not very water-soluble and so are quite durable in water. Non-hydraulic cements do not harden underwater; for example, slaked limes harden by reaction with atmospheric carbon dioxide. The most important uses of cement are as an ingredient in the production of mortar in masonry, and of concrete, a combination of cement and an aggregate to form a strong building material.

Chambers 20th Century Dictionary

  1. Cement

    se-ment′, n. anything that makes two bodies stick together: mortar: a bond of union.—v.t. to unite with cement: to join firmly.—n. Cementā′tion, the act of cementing: the process by which iron is turned into steel, glass into porcelain, &c.—done by surrounding them with a cement or powder and exposing them to heat.—adjs. Cement′atory, Cementi′tious, having the quality of cementing or uniting firmly. [O. Fr. ciment—L. cæmentum, chip of stone used to fill up in building a wall, cædimentumcædĕre, to cut.]

Military Dictionary and Gazetteer

  1. cement

    Hydraulic cements are much used in building permanent fortifications. The cement used by the Romans in their great sea-walls, aqueducts, etc., which are still standing as monuments of their civil engineering, was pozzuolana, a volcanic earth from near Baiæ, Italy. It is still an article of export from Italy. The most noted modern cement is Portland, made artificially in England by burning a mixture of the chalk and clay from the valley of the Medway.
