Definition: In limestone, the generally recognized standard machine finish produced by the planers. Also known as “machine smooth” or “planar” finish.
Definition: Cleaning and/or other remedial activity performed on a scheduled basis: daily, weekly, etc. in order to remove dirt, dust and other contaminants that degrade the stone’s appearance and/or performance.
Definition: A metamorphic crystalline rock composed predominantly of crystalline grains of calcite, dolomite, or serpentine, and capable of taking a polish. Commercial and scientific definitions of the marble group are explained in detail in ASTM C119.
Marble (commercial definition)
Definition: A crystalline rock, capable of taking a polish, and composed of one or more of the minerals calcite, dolomite, and serpentine. Commercial and scientific definitions of the marble group are explained in detail in ASTM C119.
Marble Institute of America
An international trade association whose membership is composed of producers, fabricators, contractors, exporters, importers, distributors, sales agents, and vendors who provide products and/or services to the dimension stone industry and building owners. MIA traces its roots back to the National Association of Marble Dealers, founded in 1907, which joined with the National Association of Marble Producers in 1944 to form the Marble Institute of America (MIA). The National Association of Marble Builders merged with MIA in 1962.
Built up construction, usually individual units set in mortar.
That branch of construction dealing with plaster, concrete construction, and the laying up of stone, brick, tile and other such units with mortar.
Definition: Rock altered in appearance, density, crystalline structure, and in some cases, mineral composition, by high temperature and intense pressure. Includes slate derived from shale, quartz based stone from quartzitic sand, and true marble from limestone.
Definition: The change or alteration in a rock caused by exterior agencies, such as deep-seated heat and pressure, or intrusion of rock materials.
Definition: Said of a stone that consists largely or wholly of crystals that are so small as to be recognizable only under magnification.
Definition: In the stone industries, comprehensive term for processing quarry blocks through sawing, planning, turning and cutting techniques to finished stone.
Definition: Any condition of stone veneer, coping, paving strips, etc, where a corner condition is accomplished by two stones with angular cuts, with the angles of the cuts being equal to the bisection of the total angle. See also quirk miter.
Definition: A sample section of stonework that is installed, often including other related construction components, for the purpose of obtaining designer and owner approval prior to commencement of quarrying, fabricating, or installation of stonework. The mockup may be independent of the project or may be part of the project and remain in place as part of the completed work.
Definition: Refers to standard patterns used throughout the stone industry that are usually based on multiples of a given height or size.
Modulus of Elasticity
Definition: Tested per ASTM C1352, the ratio of stress to corresponding linear strain of a material, expressed as a force per unit area (lbs/in² or pascals), and used as a measure of a material’s stiffness. Also known as “Young’s Modulus.”
Modulus of Rupture
Definition: A bending strength test, normally performed per the ASTM C99 test method, in which a small sample of stone (8” x 4” x 2¼”) is supported by two support rods, and loaded to failure by a third rod positioned at the center of the span. The results are reported as the stress experienced by the stone sample at the time of specimen failure, and expressed as a force per unit area (lbs/in² or pascals). See also flexural strength.
Definition: A relative scale of mineral hardness developed by German Mineralogist Friedrich Mohs in 1822 ranking ten common minerals by their scratch resistance.
Definition: Decorative stone deviating from a plane surface by projections, curved profiles, recesses or any combination thereof.
Definition: Shaped from a single block of stone, in contrast to a unit that was created by using multiple units of stone.
Definition: A mixture of cement paste and fine aggregate used in setting stone units or filling joints between stone units. Mortar may contain masonry cement, or may contain hydraulic cement with lime (and possibly other admixtures) to afford greater plasticity and workability than are attainable with standard portland cement mortar.
Definition: A decorative installation, usually a graphic or artwork display, made up of an assemblage of small units of different colored stones or glass to create the total image or pattern.
Definition: In tile installations, a joint where only the finish material is separated by an elastomeric filler, and the substrate is uninterrupted. Also known as a “generic movement joint.”
Definition: The abbreviation for Material Safety Data Sheet. The information required by OSHA’s Hazard Communication Standard (HCS) to convey hazardous information to downstream customers.
Definition: A structural unit that separates two window units.
