Made by burning a mixture of clay and limestone in a rotary kiln and pulverizing the resulting clinker into a very fine powder, named for its

resemblance to a limestone quarried on the Isle of Portland, England.

Classification of Portland Cement

A Portland cement having a reduced content of tricalcium silicate and an increased content of dicalcium silicate, causing it; to generate less heat of hydration than normal Portland cement; used in the construction of massive concrete structures, such as gravity dams, where a large buildup in heat can be damaging.

Classification of Portland Cement

A Portland cement having a reduced content of tricalcium aluminate, making it more resistant to sulfates and causing it to generate less heat of hydration: used in general construction where resistance to moderate sulfate action is required or where heat buildup can be damaging, as in the construction of large piers and heavy retaining walls.

Classification of Portland Cement

A Portland cement having a reduced content of tricalcium aluminate, lessening the need for gypsum, a sulfate normally added to cement to retard its setting time: used where resistance to severe sulfate action is required.

A Portland cement produced from raw materials law in iron oxide and manganese oxide, the substances that give concrete its gray color; used in precast concrete work and in the making of terrazzo, stucco, and tile grout.

A Type I, Type II, or Type III Portland cement to which a small quantity of an air entraining agent has been inter-ground during manufacture; designated by the suffix A, as in Type IA, Type IIA, or Type IIIA.

Commonly used as garden stepping stones and floor finishes

A class of rock composed of cemented silica grains. Colors include gray, buff, light brown and red.

A sedimentary rock composed mainly of calcium carbonate. It has been formed at the earth’s surface through the evaporation of water from hot springs.

Igneous origin and composed of quartz, feldspar, hornblende and mica. Its generally very hard, strong durable and capable of taking a high polish.

A nonvolatile fluid in which the solid body material is suspended. The

vehicle should consist of from 85 to 90 percent drying oil and the remainder thinner and drier.

Material which give the paint its color

Are volatile solvents, materials which have a natural affinity for the vehicle in the paint. They cause the paint to flow better.

A mixture consisting of vehicles or binders, with or without coloring pigments, adjusted and diluted with correct amounts and types of additives and thinners, which when applied on a surface, forms an adherent continuous film which provides protection, decoration, sanitation, identification and other functional properties.

A group pf more-or-less transparent liquids which are used to provide a protective surface coating, at the same time they allow the original surface to show but add a lustrous and glossy finish to it.

The only liquid protective coating containing a resin of animal origin.

The luminous flux emitted per unit solid angle by a light source, expressed in candelas.

The rate of flow of visible light per unit time, expressed in lumen.

A unit of sound absorption equal to 1 ft2 (0.90m2) of a perfectly absorptive surface

A unit for measuring the apparent loudness of a sound, equal in number to the decibels of a 1000 Hz reference sound judges by a group of listeners to be equal in loudness to the given sound

A unit for measuring the apparent loudness of a sound, judged by a group of listeners to be equal to the loudness of a 1000 Hz reference sound having an intensity of 40 decibels
