| A board used in large sheets as a backing or as a substitute for plaster in walls and consisting of fiberboard, paper, or felt, bonded to a hardened gypsum plaster core; see Gypsumboard.
|
| A mechanical device by which plaster mortar is conveyed through a flexible hose to deposit the plaster in place; also known as a plaster pump or plastering gun; distinct from Gunite machines in which the plaster or concrete is conveyed, dry, through the flexible hose and hydrated at the nozzle.
|
| The work produced by plasterers.
|
| 1. A plastic mixture of bitumen and asbestos reinforcing fibers with a solvent; see Flashing Cement. 2. Portland cement to which small amounts of plastizing agents, not more than 12% by volume, have been added at the mill.
|
| A type of conduit for electrical wiring that is used around moist areas and highly corrosive fumes.
|
| Condition in which concrete, mortar, or cement paste will sustain deformation continuously in any direction without rupture.
|
| Method of structural analysis of continuous steel structures (beams and frames) based on calculating the loading which will cause collapse of the system.
|
| The point at which a structural member such as a beam or part of a frame is bent so that a section is stressed beyond the elastic range.
|
| sheet material placed on concealed side of the panel material similar to sheet material on exposed side of panel to balance the construction of the panel and give dimensional stability by minimizing moisture absorption.
|
| Assembled plastic laminate cabinets.
|
| Countertop with plastic laminate finish covering substrate, usually plywood or particleboard.
|
| sheet material manufactured of multiple layers of paper with top layer of plastic usually 1/16 inch (1.59 mm) thick with decorative finish; may be used in flat sheets or heat formed, bent, and adhered to single curved base material; commonly referred to by the brand name of Formica.

| 800 Roosevelt Road, Building C, #20, Glen Ellyn, Illinois 61037-5833, (708) 858-6540.
|
| 1275 K Street, NW, #400, Washington, DC 20005, (202) 371-5200.
|
| Pipe manufactured from hard plastic to resist corrosion and rust.
|
| Plastic in which thickness is very small in relation to length or width.
|
| A transparent or translucent plastic molded unit that is set in a frame and mounted on a roof for use as a skylight.
|
| A soil that can be rolled into 1/8" diameter strings without crumbling; a soft rubbery soil.
|
| 1. Capable of being molded; pliant; supple. 2. Any of a number of synthetic polymeric substances that can be given any required shape. 3. In stress analysis, refers to stress/strain behavior beyond the elastic range; plastic deformation usually implies some permanent shape change. 4. A condition of freshly mixed concrete, mortar, or cement paste indicating that it is workable and readily remoldable, is cohesive and has an ample content of fines and cement but is not over wet.
|
| 1. Property of a material to deform under load and to retain the deformation after the load is removed. 2. A materials ability to be shaped and worked. 3. That property of plaster mortar that permits continuous and permanent deformation in any direction. 4. A plastic material is distinct from a fluid material in that it requires a measurable force (yield value) to start flow; the property exists in varying degrees in different materials and in plaster mortar is sometimes regarded as an index of working characteristics.
|
| 1. A substance added to plastics, resins, and rubbers to impart improved properties such as flexibility, workability, or stretchability. 2. A material that increases the workability or consistency of a concrete mixture, mortar or cement paste. 3. A product used to increase the flow and/or workability of plaster.
|
| Plasticizer.
|
| A product used to increase the flow and/or workability of plaster.
|
| softening wood by hot water, steam, or chemical treatment to make it easier to mold.
|
| Film former containing resin and plasticizer with no solvents.
|
| 1. A small piece or ground; a plot of land. 2. A drawing or map showing a plot of land.
|
| The cut at the bottom end of a rafter to allow it to fit upon the plate; the cut in a rafter which rests upon the plate; also called the Seat Cut.
|
| A large beam made up of steel plates, sometimes in combination with steel angles, welded, bolted or riveted together.
|
| Glass of high optical quality produced by grinding and polishing both faces of a glass sheet.
|
| Thick mirror glass manufactured to a high-quality standard.
