Building Technologies Practice Flashcards

This set of vocabulary flashcards covers fundamental building materials, construction processes, and structural components as detailed in the Building Technologies lecture notes.

28

The specified strength of concrete will be reached after how many days of curing?

Coursed Rubble

Fieldstone or roughly dressed stone with or without mortar.

Slump Test and Cylinder Compression Test

The two methods used for controlling the consistency of concrete mixes and strength.

Bricks

A masonry unit of clay formed into a rectangular prism while plastic and hardened by drying in the sun or firing in a kiln.

Steel

A malleable alloy of iron and carbon produced by smelting and refining of pig iron and/or scrap steel.

Grout

A fluid cement mortar that flows easily without segregation, used to fill narrow cavities in masonry and consolidate adjoining materials into a solid mass.

Sandblasted

A matte textured surface with no gloss that is the result of a pressurized flow of sand and water.

Welding

A fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence; often involving melting work pieces and adding a filler material.

Wood

Which among the following materials has the best sound-absorbing qualities?

Wrought Iron

A ferrous material which is tough and ductile, produced from pig iron in a way that removes carbon and other impurities.

Galvanized Iron

Iron coated with zinc through a process of hot-dipping to prevent rust.

Retarder

An admixture which delays the setting time of concrete, especially during hot weather conditions.

Lugs

Intentional deformations or features on steel reinforcements designed to increase adhesion to concrete.

Rubble

Rough fragments of broken stone that have at least one face good for exposure on a wall.

Mortar

A mixture of cement, sand, and water used as a bonding agent in masonry construction.

Concrete

An artificial stone-like material made by mixing water with cement and co...

Brass

An alloy of copper and zinc which is relatively resistant to tarnishing.

Chromium

A common alloy and component of Stainless Steel used for corrosion resistance.

Plywood

A type of building board made of $3$ or more layers of veneer joined by each layer.

Particle Board

Made from hardboard using relatively small particles graduated from coarse at the center to fine at the surface to produce a smooth dense surface.

Gypsum Board

A wall or ceiling board (also called Wallboard or Drywall) having a chalk-like material core clad with paper.

Porcelain Tiles

Tiles made with finer clay particles fired at higher temperatures to achieve greater water resistance than ordinary tile.

Primer

A base coat applied to improve the adhesion of substance

Solvent

A component that dissolves paint to make it usable and workable.

Primer

A base coat applied to improve the adhesion of a substance.

Sagging

A paint defect characterized by an uneven coating due to the excessive application of paint on wet paint.

Integral Waterproofing

A waterproofing type mixed with concrete that creates a waterproof structure without requiring skilled workmanship for application.

Annealed Glass

Float glass that has not been heat-strengthened and has undergone a process of controlled cooling to prevent residual stress.

Tempered Glass

Safety glass processed by thermal or chemical treatments to increase strength, causing it to shatter into small granular chunks when broken.

Isolated Footing

A single spread footing supporting a freestanding column or pier.

Truss

A structure composed of chords, diagonal, and vertical web members to create a rigid framework.

Bridging

An arrangement of braces fixed between floor joists to keep them in place and distribute the load to adjacent joists.

Cantilever Beam

A beam supported only on one end.

Flashing

Material used to prevent water penetration and/or provide water drainage, especially between a roof and a wall.

Gutter

A channel of metal, wood, or concrete set below and along the eaves of a building to catch and carry off rainwater.

Class A Concrete Ratio

A concrete mixture ratio of $1:2:4$ (cement:sand:gravel).

Splice

To connect or join two similar materials, usually in a straight line, by means of mechanical connectors, welding, or wire connection.

Effective Depth

The measure from the top of a concrete beam to the center of the bottom bar.

Differential Settlement

The relative movement of parts of a structure caused by uneven settlements of the underlying soil.

Concrete Cover (Weather Exposed)

The concrete cover required for cast-in-place concrete exposed to weather is $75\,mm$.
