Flashcards in 5 Deck (49):
The chemically inert element of concrete, usually consisting of sand, gravel, and/or other granular material.
An overhead source of natural light, generally installed on a roof.
The ratio of water to cement in a concrete mix, the main factor that determines concrete strength.
The level below which the subsoil is completely saturated with water. Also called the groundwater level.
Masonry finish material which is attached, but not structurally bonded, to the backing. Also, a thin layer or sheet of wood produced by slicing or rotary cutting.
A continuously moving, power-driven mechanical device that transports passengers along an incline from one floor to another. Also referred to as an escalator.
Clear, flat sheet glass that is most commonly used for glazing.
A device located at the bottom of an elevator hoistway, used to stop a cab's overtravel at low speed, not to stop a free-falling cab. Also referred to as buffer.
The moisture content at which soil starts to change from a semisolid to a plastic state.
Fill that has been densified by the application of pressure, usually by mechanical equipment, in order to increase it's strength and stability and reduce it's settlement. Properly compacted fill is often suitable for the support of building footings.
A laminated panel of thin wood veneers, or plies, permanently bonded together with an adhesive. The grain of the adjacent plies is usually placed at right angles.
An opening in a wall or parapet for the drainage of rainwater from a roof.
A continuous series of steps extending from floor to floor, floor to landing, or landing to landing.
The part of a building's structure that transmits the building's load to the underlying soil.
Describing inlaid wood flooring, generally set in a traditional geometric pattern.
Permitting leakage or flow of water.
Temporary support for a portion of a building.
Unequal settlement of the various parts of a building, which may cause excessive stresses in the structural frame or tilting of the building.
Concrete containing adequate reinforcing steel and designed on the basis that the concrete and steel act together in resisting forces. The concrete is usually assumed to resist compression, while the reinforcing steel is assumed to resist tension.
Sheet glass containing an embedded wire mesh for strength and safety.
A moveable enclosure that provides vertical transportation for a building's occupants or freight and that serves two or more floors. The common elevator types are electric and hydraulic.
The masonry bond pattern in which all the head joints form a continuous vertical line and no units overlap.
The removal from a site of unwanted roots, stumps, and so on during excavation.
To pack a damp concrete mixture into a confined space.
An elevator used to vertically transport equipment, materials, and goods, rather than passengers.
Maintaining concrete at the proper moisture and temperature after it is cast.
A mortar joint that has been cleaned of mortar for about 3/4" back from the face.
A lightweight aggregate used in lightweight concrete or plaster.
Brick made for exterior use with special consideration of color, texture, and size.
A concrete element in a location other than it's final position. After curing, it is moved to it's final location and installed.
premium appearance grade
The best appearance grade for glue laminated members, used where the finest appearance is required.
A metal strip placed on corners before plastering to reinforce and protect the corner. Also referred to as an angle bead.
The horizontal surface of a stair step; its width is the horizontal distance between risers.
A hard, cross-grained mass of wood caused by a branch or limb joining the trunk of a tree and cut through in the process of lumber manufacture.
An underground wood, concrete, or steel member, usually vertical, and usually driven into place, which is used to support building loads.
The most usual welding process used in building construction, in which intense heat is produced by an electric arc between the members to be joined and a metal wire or rod, called the electrode.
A numerical classification indicating the rate at which flame will spread over the surface of a given material. Class I materials have the least flame-spread and Class III have the most.
The decomposition of wood caused by fungi.
Opaque glass used in block, sheet, or tile form for exterior building panels.
Distortion of timber during seasoning caused by changing moisture content.
Two sheets of glass with an air space between, to insulate against the passage of heat or sound. Also called insulating glass.
A framework of horizontal members used to spread a structural load over a large area.
The time, in hours, that a material or assembly of materials can withstand exposure to fire.
A medium carbon steel, rolled in a variety of shapes and sizes for use as load-bearing structural members.
A type of fire-resistive door that has a solid wood core covered with sheet metal.
Laminated glass, consisting of a thin sheet of transparent plastic laminated between two layers of clear glass. Also referred to as safety glass.
Describing wood that is seasoned by exposure to the atmosphere without artificial heat.
A method of building reinforced grouted masonry walls in which a large area of the wall is set and then the grout is placed, usually by pumping.
