Also called calcspar, a common crystalline form of natural calcium carbonate, CaCO3. It is the main mineral composing most limestones and geological marbles.
A limestone containing not more than 5% of magnesium carbonate.
A crystalline variety of limestone containing not more than 5% of magnesium carbonate.
Commonly described as a white or milk-like streak in stone. It is a joint plane, usually wider than a glass seam, that has been re-cemented by deposition of calcite in the crack. It is structurally sound.
Calcined limestone. See also, Quicklime.
A slight rising from the horizontal, to gain an actual or apparent effect of arching.
A volcanic, quartz-based stone with qualities similar to adoquin, but not as dense. Quarried in Mexico.
The crowning stone of a structure; differing from Capital in that it is not a supporting member.
The ability of masonry to store heat as a result of its mass, density, and specific heat.
The movement of a liquid in the interstices of a porous material, as a result of surface tension. The phenomenon responsible for dry materials sucking moisture above the normal water level.
The crowning stone of a column, differing from Cap Stone in that it is a supporting member.
A salt of carbonic acid.
A weak acid.
A precast concrete building stone manufactured to simulate dimension stone.
A substance that accelerates a chemical reaction but appears to remain unchanged itself (i.e. a hardener that accelerates the cure of synthetic resin adhesive).
Non-staining, non-hardening, putty-like mastic, usually applied to stone joints with a pressure gun.
A hydraulic mixture, without aggregate, consisting of a calcined mixture of clay and pulverized limestone.
To bevel the junction of an exterior angle, or to cut away the edge where two surfaces meet in an external angle, leaving a bevel at the junction.
Description of a textured stone finish, obtained by using chat sand in the gang sawing process.
A small, irregularly shaped stone piece dislodged, usually from the edge, from a larger stone piece.
A stone face worked to a convex spherical shape.
CIRCULAR SUNK FACE
A stone face worked to a concave spherical shape.
An exterior veneer stone covering.
Stone fragments that are derived from pre-existing rocks or miner
A natural mineral aggregate consisting essentially of hydrous aluminum silicate. It is plastic when sufficiently wetted, stiff when dried, and vitrified when fired to a sufficiently high temperature
A soft, low lime mortar usually used when lime was expensive and difficult to procure. Its primary usage was in remote areas for small scale buildings
The visible end of a stone laid as a bond stone
Openings at the bottom of a grout space for cleaning mortar droppings and other debris prior to grout placement
An invisible to glossy film or penetrate applied to substrates to protect, repel or resist water and hydration of minerals
Space allowed to facilitate erection of units and provide for thermal and other estimated movements in structure
The ability of a rock mass to break along natural surfaces; a surface of natural parting. Also used to refer to the plane or planes along which a stone may likely break or delaminate
Membrane that provides a separation and slip sheet between the mortar setting bed and the backing or base surface
Plane or planes along which a stone may likely break or delaminate
Rough-surfaced stones such as slates that are cleaved or separated along a natural seam are referred to as natural cleft. These types of stones were formed as a result of metamorphic foliation
A protective or decorative covering applied to the surface or impregnated into stone for such purposes as waterproofing, enhancing resistance to weathering, wear, and chemical action, or altering the app earance of the stone
A dimension stone large enough for use in paving. A term commonly used to describe paving blocks, usually granite, and generally cut to rectangular shapes
A crystalline rock composed predominately of one or more of the following minerals: calcite, dolomite, or serpentine, and capable of taking a polish
Rocks that are traded as marble but are not metamorphic rocks. (They preserve their sedimentary nature.)
A construction unit in which stone that is to be exposed in the final use is permanently bonded or joined to concealed material
Dampness of interior surfaces caused by the release of water as it cools below the dew point; the formation of frost or water when air carrying water vapor comes in contact with a cold surface, cooling the air and reducing its ability to hold moisture
A stone similar to sandstone but the rock particles are rounded or angular gravel rather than sand; an aggregate of rounded and water-worn pebbles and boulders cemented together into a coherent stone
Treatment of the stone surface with a liquid solution which is commonly brush or spray applied. Various stone consolidation processes can extend the life of stone and retard the decay process, but they cannot permanently arrest deterioration
A crust forming across the surface of sandstones and limestones which follows the contour of the surface rather than the bedding planes of the stones. The result of direct pollution. The pores of the stone are blocked by formations of recrystallized calcium sulfates
A joint that allows for dimensional changes of different parts of a structure due to shrinkage, expansion, variations in temperature, or other causes. Its purpose is to prevent development of high stresses in the structure
The horizontal top stone of a wall or similar stone construction, usually flat
A cap or covering course on top of masonry wall. Designed to shed water, protect the top and provide a finished, closed appearance to the wall. Commonly extended beyond the wall face and incorporating a drip.SEC: Single edge coping.DEC: Double edge coping
Limestone composed predominately of shells or fragments of shells loosely cemented by calcite. Coquina is course-textured and has a high porosity. The term is applied principally to a very porous rock quarried in Florida
A limestone consisting of the calcareous skeletons of corals, often containing fragments of other organisms and usually cemented by calcium carbonate
A stone forming a part of a corner or angle in a wall. Also a stone laid at the formal inauguration of the erection of a building
A molded projecting stone at the top of an entablature or facade
items which have been treated or coated to retard harmful oxidation or other corrosive action
A continuous horizontal band of stone of constant height
This is achieved by using stones of the same or approximately the same heights. Horizontal joints run on the entire length of the veneered area. Vertical joints are constantly broken so that no two joints will be over one another
French for the stone at the top of a pier supporting the lowest stone of an arch
A concave stone mold
A concave joint shaped with a tool
A break, split, fracture, fissure, separation, cleavage, or elongated narrow opening, however caused, visible without magnification to the human eye and extending from the surface into the stone, through the gra in, matrix, or vein
A U shaped metal anchor for holding two adjacent units of stone together
A multi-pointed hammer for dressing the face of stone
Depression in a coating film usually caused by air or solvent trapped in the coating, forming bubbles which break after the film has set sufficiently to prevent leveling
(Croissette, Crosset) A side lug at the upper side of an arch stone, entering a corresponding space on the adjoining stone
