Portland cement mortar (often known simply as cement mortar) is created by mixing Portland cement with sand and water. It was invented in the mid-19th-century, as part of scientific efforts to develop stronger mortars than existed at the time. It was popularised during the late 19th century, and by 1930 it had superseded lime mortar for new construction. The main reason for this was that it sets hard and quickly, allowing a faster pace of construction. Portland cement mortar is the basis for concrete, a mixture usually comprised of this particular mortar with the addition of gravel.  3, record 1, English, - Portland%20cement%20mortar

Le ciment Portland donne au mortier de maçonnerie sa résistance mécanique, en particulier sa résistance initiale, qui est indispensable à une époque où la vitesse de construction est telle que l'on exige qu'un mur puisse supporter une charge importante le lendemain même de sa construction. Les mortiers de ciment Portland manquent de plasticité, ont un faible pouvoir de rétention d'eau et sont malaisés à travailler.  3, record 1, French, - mortier%20de%20ciment%20Portland

Béton. Mortier de ciment. Ces matériaux ont tendance à poussiérer, en «s’effritant» (phénomène accru avec l’âge du matériau). Par leur porosité naturelle et leur grain de surface, ils s’encrassent, en accrochant les salissures et souillures diverses. Ils sont sensibles à certains agents chimiques, et notamment aux acides, même faibles. Ainsi, des composés qui nous semblent inoffensifs comme certains dérivés du lait (acide lactique), les jus de fruit, le jus de tomate, la choucroute, le gypse (en présence d’eau), tout comme les solutions salines (saumures, sels de déverglaçage), attaquent de façon spectaculaire les matériaux à liants hydrauliques.  2, record 2, French, - mortier%20de%20ciment
