  2. Bulk density - Wikipedia

    en.wikipedia.org/wiki/Bulk_density

    The density of quartz is around 2.65 g/cm 3 but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm 3. In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities ( <1.0 g/cm 3 ) due to a combination of the low-density of the organic materials ...

  3. Void ratio - Wikipedia

    en.wikipedia.org/wiki/Void_ratio

    where is the void ratio, is the porosity, V V is the volume of void-space (gases and liquids), V S is the volume of solids, and V T is the total (or bulk) volume. This figure is relevant in composites , in mining (particular with regard to the properties of tailings ), and in soil science .

  4. Polystyrene - Wikipedia

    en.wikipedia.org/wiki/Polystyrene

    According to the EPS-IA ICF organization, the typical density of EPS used for insulated concrete forms (expanded polystyrene concrete) is 1.35 to 1.80 pounds per cubic foot (21.6 to 28.8 kg/m 3). This is either Type II or Type IX EPS according to ASTM C578. EPS blocks or boards used in building construction are commonly cut using hot wires. [54]

  5. Elastic properties of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Elastic_properties_of_the...

    Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

  6. Filler (materials) - Wikipedia

    en.wikipedia.org/wiki/Filler_(materials)

    Plastic consumption uses by field. Filler materials are particles added to resin or binders (plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both. [1] The two largest segments for filler material use is elastomers and plastics. [2]

  7. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1] Reinforced concrete is the most common form of concrete.

  9. Porosity - Wikipedia

    en.wikipedia.org/wiki/Porosity

    Aggregation involves particulate adhesion and higher resistance to compaction. Typical bulk density of sandy soil is between 1.5 and 1.7 g/cm 3. This calculates to a porosity between 0.43 and 0.36. Typical bulk density of clay soil is between 1.1 and 1.3 g/cm 3. This calculates to a porosity between 0.58 and 0.51.
