Numerical value, which represents the physical property of a material, used in calculation or structural computations, and represents the reaction of a material under certain conditions.
Modulus of elasticity
Ratio of stress applied to a material with relation to the deformation amount that results from the application of that stress to the material. The ability of the material, once the stress is removed, to recover its original shape.
Moenstone
A blend of ceramic-like quartz (70%) and acrylic polymer (30%) that is impervious to chips or water spots.
Mohs'scale
Scale used to express the measure of a material's hardness from Mohs' 1 (hardness of talc) to 10 (diamond). Moh's Hardness this test does not have an ASTM designation but is useful as it determines the hardness of the glaze. A scratch is made on the tile being very soft (Talc) and 10 being very hard (Diamond). Tiles rated 6 to 7 or higher are relatively scratch resistant and can be used on floors or countertops.
Moist
(1) Slightly wet. Damp. (2) Suggesting the presence of liquid. (3) Atmosphere with high humidity.
Moisture
Water or other liquid causing a slight wetness or dampness.
Moisture barrier
A layer of foil, plastic or paper used in the construction of exterior walls, ceilings and foundations to prevent moisture penetration into wooden members or insulation.
Moisture content
The amount of moisture in wood expressed as a percentage of the weight of the oven dry wood.
Moisture control
The process of controlling indoor moisture levels and condensation.
Moisture density curve
Graph showing the soil moisture content as compared to the density of the soil that can be achieved with that moisture content. Moisture content of the soil is important to the amount of compaction possible. The ability to support a load is increased by the density of the soil, which is achieved through compaction.
