Flashcards in 3 Deck (49):
The blasting of concrete with sand or another abrasive material to dull the formed surface, make the color uniform, or expose the aggregate.
A test for mixed concrete to determine consistency and workability.
A corridor that is closed at one end, usually limited to 20 feet in length.
An impervious material used to prevent water penetration at joints formed by different materials or surfaces.
Lumber of all sizes and patterns intended for general building purposes.
A groove in a concrete structure made to predetermine the location of cracks.
A round threaded metal device with a bell-shaped end that is used to anchor stone.
A unit of measure for lumber equal to the volume of a board 12"x12"x1".
A method of producing a metal product by pouring molten metal into a mold of the desired shape.
The pressure exerted by a liquid against every surface it contacts.
An elevator operated by traction, in which steel cables with counterweights raise or lower the elevator car.
A short beam passed through a wall to provide temporary support.
A simple structural system consisting of beams simply supported on posts.
A solid or hollow unit of translucent glass used for non-load-bearing walls.
A material characterized by opaqueness, hardness, the ability to conduct heat and electricity, and a distinctive luster when untarnished.
Glass that has greater resistance to impact, thermal stresses, and wind than annealed glass, but less than that of tempered glass.
A thin impervious layer of material that prevents water penetration, as in a built-up roof or wall below grade.
The load-carrying unit of an elevator, including its platform, frame, enclosure, and door. Also referred to as an elevator cab.
An opening between growth rings containing pitch or resin.
A knurled or roughened finish applied to operating hardware on doors leading to areas that might be hazardous to visually impaired persons.
A reinforced concrete wall that is precast at the job site, usually in a flat position, and later tilted up and set into place.
wet pipe sprinkler
A sprinkler system that is continuously pressurized with water. If a fusible sprinkler opens, water is immediately forced through the sprinkler head.
Impervious to water or water vapor, even under pressure.
A natural or manufacturing imperfection in wood that may affect its strength, appearance, use, or grading. Included are knot, pitch pocket, shake, check, split, and wane.
A stream of air that is directed downward across an opening, to exclude drafts, insects, and so on.
Wood or metal strips used to make a plane surface; also a cavity within a wall or ceiling.
industrial appearance grade
The appearance grade used for glue laminated members where appearance is not of primary concern.
A vertical member between windows or doors.
A material used to prevent or reduce sound transmission or heat flow.
A hollow concrete masonry unit.
Sheet steel in a corrugated, ribbed, or cellular form and used for structural load-carrying purposes in floor or roof construction.
A large-toothed roller used for the compaction of soil.
A horizontal member supporting joists.
An alloy of iron and carbon, with a carbon content between 0.1 and 1.7% (more than that of wrought iron and less than that of cast iron).
The maximum depth of frost penetration in the ground expected in a given area.
Reference points offset a given distance from the building line and set prior to excavation.
The slope or incline of a roof expressed in degrees or as the ratio of a vertical rise to the horizontal run.
Brick, block, tile, stone, or similar materials bonded together with mortar.
A member beneath a door, to cover the floor joint or provide weather protection. Also called a saddle.
A door having hardware that permits it to swing in either direction from the plane of its frame.
Timber decay due to fungus, in which pockets of dry powder develop.
A device used to support reinforcing bars during the placing of concrete.
Sheet metal or wire fabric into which a base coat of plaster is keyed.
Lengthwise separation of wood extending from one face through to the opposite face.
The second coat of plaster, in three-coat plastering, which is applied over the scratch coat and beneath the finish coat. The large proportion of sand in this mixture gives the coat it's name.
Bark or lack of wood on the edge or corner of a piece of wood.
Soil with a high organic content (decomposed vegetable or animal matter). Organic soils are usually very compressible and have very low bearing capacities.
The science of sound and sound control.
