- n. Any composition which at one temperature or one degree of moisture is plastic and at another is tenacious. Cements are used for uniting materials of the same kind or of different kinds, or for forming smooth and impervious surfaces or coatings. The term properly includes papier-maché, gums, glues, mucilages, limes, mortars, and a great number of compounds of such nature as to admit of their assuming, under certain conditions, sticky, tenacious, or stone-like consistency. Cements are divided into classes, according to their use, as glass-cement, etc. The materials forming the cement are mixed with water, acids, oils, etc., to a paste, and applied to the surfaces to be joined together or coated, and then dried; or, either wet or dry, are applied hot, or are applied and then heated, when they become hard and tenacious. This hardening is called the “setting” of the cement. The cements in use in the arts are exceedingly numerous, and are composed of a great variety of materials.
- n. Specifically A kind of mortar which sets or hardens under water: hence often called hydraulic cement. It is, however, often used in superior masonwork not intended to be covered by water. There are two kinds of cement well known in Europe, Portland and Roman. Portland cement (named from its resemblance in color to Portland stone) is made from selected materials, commonly chalk and river-mud or alluvial clay. Roman cement (unknown to the Romans, but deriving its name from a supposed resemblance to Roman mortar) was originally made of volcanic ashes, but is now more often made from materials obtained from the Jurassic series of rocks. Much of the cement used in the United States is that known as Rosendale. See
- n. A name sometimes given by placer and hydraulic miners to any rather firmly compacted mass of detrital auriferous material.
