Or, the vertical face on buildings supported by a skeleton structure between the sill of one window and the top or lintel of the window next below. Quartz-based Stone This stone may be either sedimentary in formation or metamorphic. Porosity Ratio of pore space to the total volume of material expressed as a percent.. Class Of Unit A ranking of masonry units according to their different grades or types in ASTM specifications, the different raw materials they are manufactured from, or other characteristics. Initial Rate Of Absorption The weight of water absorbed when a brick is partially immersed in water for one minute, expressed in grams per 30 square inches of contact surface, also called suction.
Set A change in mortar consistency from a plastic to a hard state. Stone which comes palletized is easily moved and transported by modern handling equipment. Composed essentially of silicate minerals with interlocking and visibly granular texture in which the foliation is due primarily to alternating layers, regular or irregular, of contrasting mineralogic composition. Sculpture The work of a sculptor in three dimensional form by cutting from a solid block of stone. Sandblasted, Coarse Stippled Coarse plane surface produced by blasting with an abrasive; coarseness varies with type of preparatory finish and grain structure of the stone. Face Refers to the exposed surface of stone on the structure.
Adhered Stone veneer secured and supported by adhesion of an approved bonding material over an approved backing. It is a joint plane that has been recemented by deposition of translucent crystalline calcite in the crack and is usually structurally sound. Their life span is generally less than that of inorganic material, but they can be especially effective with porous stone as well as comprehensive strengths. Checker Work Masonry of square-face stones not breaking joints. Parapet A low wall around the perimeter of a building at roof level or around balconies.
Parclose A screen of stone separating chapels, especially at the east end of the aisles, from the body of the church. Pitched Stone Stone having arris clearly defined, face however is roughly cut with pitching chisel used along the line which becomes the arris. Finish Final surface applied to the face of dimensional stone during fabrication. It also acts as a binding agent and gives hardness to the cake. Blending Refers to the proper positioning of adjacent veneer panels, or floor slabs, or tiles by their predominant color to achieve an overall uniform pattern. Erection The process of and setting vertical dimensional stone in place. Centering Temporary formwork for the support of masonry arches or lintels during construction.
