| Refrigerating system of variable capacity.
|
| Type of device or control which tends to adjust by increments (minute changes) rather than by either full on or full off operation.
|
| A standardized part or independent unit used in construction.
|
| A concept of modulus of elasticity expressed as a function of two time variables; strain in loaded concrete as a function of the age at which the load is initially applied and of the length of time the load is sustained.
|
| The ratio of the unit stress in a material to the corresponding unit strain; the ratio of normal stress to corresponding strain for tensile or compressive stresses below the proportional limit of the material; referred to as elastic modulus of elasticity, Youngs modulus, and Youngs modulus of elasticity; denoted by the symbol E.
|
| The ratio of unit shearing stress to the corresponding unit shearing strain; referred to as shear modulus and modulus of elasticity in shear; denoted by the symbol G.
|
| A measure of the ultimate load-carrying capacity of a beam and sometimes referred to as rupture modulus, or rupture strength; it is calculated for apparent tensile stress in the extreme fiber of a transverse test specimen under the load which produces rupture.
|
| Ratio of load per unit area of horizontal surface (of a mass of soil) to corresponding settlement of the surface.
|
| A screw-in style base for an incandescent lamp of generally 300 watts or more.
|
| Curing with moist air at atmospheric pressure and a temperature of about 70° F.
|
| see Cure, 4.
|
| A room in which the atmosphere is maintained at a selected temperature (usually 23.0° C ±1.7° C or 73.4° F ±3.0° F) and a relative humidity of at least 98 percent, for the purpose of curing and storing cementitious test specimens; the facilities must be sufficient to maintain free moisture continuously on the exterior of test specimen.
|
| A membrane used to prevent the migration of liquid water through a floor or wall.
|
| The amount of water contained in the wood, usually expressed as a percentage of the weight of ovendry wood.
|
| 1. The amount of water in a substance; in wood, it is usually expressed as a percentage of the weight of the ovendry wood.
|
| An increase in dimension or bulk volume of a ceramic article caused by reaction with water or water vapor; this reaction may occur in time at atmospheric temperature and pressure, but is expedited by exposure of the article to water or water vapor at elevated temperatures and pressures.
|
| Instrument used to measure moisture content of a refrigerant.
|
| An instrument that measures electrical resistance in a material and equates it to the amount of ambient moisture content; often used by painters to judge the suitability of plaster, masonry, or other surface for the application of paint.
|
| The movement of moisture through a porous medium; the effects of such movement on efflorescence and volume change in hardened cement paste, mortar, concrete, or rock.
|
| The act or process of retarding the seepage of moisture.
|
| Moisture vapor transmission rate through a membrane.
|
| see Absorbed Moisture.
|
| Finely divided particles of water; vapor.
|
| A mineral oil that is applied to the interior surface of a clean mold, before casting concrete or mortar therein, to facilitate removal of the mold after the concrete or mortar has hardened.
|
| see Casting Mold.
|
| see Running Mold.
|
| A divider containing a cavity into which neat cement, mortar, or concrete test specimens are cast; a form used in the fabrication of precast mortar or concrete units (e.g., masonry units); also spelled mould.
|
| Plywood made to some desired shape other than perfectly flat; often this shaping is done at the time the layers are glued together; two ways of molding plywood are by applying fluid pressure and with curved forms.
|
| A fast-setting gypsum plaster used for the manufacture of cast ornaments.
|
| see Base Molding.
