Gypsum plasters have been lightened by using chemical additives to create bubbles that displace solids, thus reducing the bulk density.
22.
The intrinsic factors of grain includes, color, composition, bulk density, odor, aroma, size and shape.
23.
For P-waves, the relation between velocity and bulk density of the medium has been quantified in Gardner's relation.
24.
Nutrients may then be mineralization, increased bulk density, spreading of the organic matter and humus, and increased rate of decomposition.
25.
As a consequence water and air is displaced and soil bulk density increases, resulting in a reduced permeability for water and air.
26.
Typically, a powder can be compacted or loosened into a vastly larger range of bulk densities than can a coarser granular material.
27.
For the dry bulk density, the sample is oven dried and weighed, giving the mass of soil solids, M _ s.
28.
The larger avoirdupois pound for goods of commerce might have been based on volume of water which has a higher bulk density than grain.
29.
The experiment showed that the plants with the greater sediment levels had more plant cover, with higher plants and a greater bulk density.
30.
Main physical negative effects to plants are restricted root growth and accessibility of nutrients due to increase in bulk density and reduced pore size.
