Flash Cards Study - Materials and Methods

Four basic types of mortar in order of strength: M is strongest, followed by S, N & O.
M or S: Used at or below grade for foundation walls, retaining walls, pavements and walks.
N: Used on exterior and interior, above grade load-bearing walls.
O: Used on exterior and interior non-load bearing walls.

Identify hinge types:
Full Mortise: Most common. Fully Mortised (think hidden) into the door edge and jamb
Half Mortise: Surface applied to door frame. Mortised (hidden) into edge of door.
Half Surface:One leaf is mounted on the face of the door and the other half is mortised into the frame.
Full Surface: Applied to the face fo the door and frame. (fully visible)

Vehicle:
The liquid portion of any paint mixture consisting of binders, dryers and solvents. Binder forms the film of the coating. Solvent dissolves the binder to allow for application and then evaporates.

Types of Terrazzo:
Standard: Most common, Made with small chips less than 3/8" in size.
Venetian: Has larger than 3/8" chips. A thicker topping is required to carry the larger sized chips.
Palladiana: 1/2" or larger, random, fractured chips, set in an underbed and then filled with standard terrazo
Rustic: A textured surface created by washing the fill prior to setting.

Wrought Iron:
Almost pure iron with a very low carbon content. Soft, but strong. Extremely ductile (pliable), easily worked and relatively resistant to corrosion. Cannot be cast, tempered or easily welded. Used for plumbing pipes, ornamental iron work, grilles and outdoor furniture.

Cast Iron:
Steel having a high carbon content, 1-1/2 to 4 percent. High compressif and tensile strength, although it is hard and brittle. Used for pipes, plumbing fixtures and ornamental iron work.

Terne-Plate:
Often used in roofing, an alloy of lead and tin. Usually applied over a sheet of steel.

Identify stair components:
Stringer: the support on which the stair treads rest. Placed ouside of the carriage to provide a finish. (exposed)
Riser: The vertical face of a step
Kicker: A plate (commonly a 2x sleeper nailed to floor) used to anchor the lower end of a carriage.
Carriage: Rough timber supporting the steps of wood stairs. (concealed)
Ledger: A plate (typically a 2x) used to support the upper end of a carriage.
Tread: the part of a stair onto which one steps. Horizontal member of the surface.
Nosing: the portion of a tread that projects beyond the riser below.
Baluster: Small pillar or column used to support the railing. (vertical supports that railing attaches to.)
Handrail: Finish material that serves as a hand rest, guide and support. Runs parallel to the stringer and stair nosings.
