However, this premise is valid only as long as the emplaced bentonite maintains a uniform high dry density (⩾1600 kg/m3) because it has been shown that high dry density only suppresses microbial activity but not necessarily eliminates the viable microbial population in bentonite.
At higher dry density, qu is greater.
It can be described as raw volcanic sand with a comparatively high dry density of 3.17 g/cm3.17
The outerwood boards were of higher dry density and lower MFA (and in turn, faster acoustic velocity), resulting in a higher longitudinal dynamic modulus as has been widely reported (Lachenbruch et al. 2011).
Experimental results showed that the swelling pressure increased with an increase in dry density, and its dependence on dry density increased at higher dry densities beyond 1.6 Mg/m3.
In the case of conservation tillage, the soil structure demonstrated higher dry bulk density as well as lower air capacity and saturated hydraulic conductivity.
For example, the microfracture-dominated samples have a relatively low permeability, fast sonic wave velocity, low connected porosity, and high dry bulk density.
Arora [3] noted that heavy clays of very high plasticity have very low moderate dry density and high optimum water content, which is consistent with the view that high OMC and low moderate MDD is suggestive of moderate materials.
However, for both variants the virgin compression section of the stress/bulk density functions displayed similar compression behaviour; and generally higher settlement for conventional tillage in the compression test did not result in higher dry bulk densities than with conservation tillage.
