Formulas; Submerged density = Submerged mass/Volume. DEGREE OF SHRINKAGE: WebAfter saturation (24 h), the samples were placed on a tension table to determine their field capacity and macroporosity. After this period, the samples were oven-dried (105 °C) until a constant mass was obtained for the determination of microporosity and soil density. Soil aggregates (≤ 19 mm) were collected and tested for stability in water.
WebIntroduction The unit weight, also known as the ‘weight density’, of a soil refers to its weight per cubic metre and is typically expressed as kilonewtons per cubic metre (kN/m3), or … WebTest Procedure. The procedure of the Proctor Compaction Test consists of the following steps: Obtain about 3 kg of soil. Pass the soil through the No. 4 sieve. Weight the soil mass and the mold without the collar (W m ). Place the soil in the mixer and gradually add water to reach the desired moisture content (w).
WebPractical Application. In-situ density is widely used to control the field compaction of earthworks and pavement layers. Knowing the field density of the soil enables the estimation of the soil-bearing capacity, evaluation of the pressure on underlying strata, and computation of the settlement and stability of a natural slope. WebSoils rich in organic matter (e.g. peaty soils) can have densities of less than 0.5 g/cm 3. Bulk density increases with compaction (see Subsurface Compaction fact sheet) at depth …
