Void ratio - Wikipedia

2019-09-30  If void ratio is high (loose soils) voids in a soil skeleton tend to minimize under loading - adjacent particles contract. The opposite situation, i.e. when void ratio is relatively small (dense soils), indicates that the volume of the soil is vulnerable to increase under loading - particles dilate.

Carbon-to-nitrogen ratio - Wikipedia

2019-10-01  A carbon-to-nitrogen ratio (C/N ratio or C:N ratio) is a ratio of the mass of carbon to the mass of nitrogen in a substance. It can, amongst other things, be used in analysing sediments and compost. A useful application for C/N ratios is as a proxy for paleoclimate research, having different uses whether the sediment cores are terrestrial-based or marine-based.

Soil consolidation - Wikipedia

2019-10-06  Soil consolidation refers to the mechanical process by which soil changes volume gradually in response to a change in pressure.This happens because soil is a two-phase material, comprising soil grains and pore fluid, usually groundwater.When soil saturated with water is subject to an increase in pressure, the high volumetric stiffness of water compared to the soil

Soil void ratio - Geotechdatafo

2018-03-09  Soil void ratio (e) is the ratio of the volume of voids to the volume of solids: e = (V_v) / (V_s) Where V_v is the volume of the voids (empty or filled with fluid), and V_s is the volume of solids. Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil.

Soil mechanics - Wikipedia

2019-10-15  Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils.It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic solids and other matter.

Optimal Soil-to-Compost Ratio for Raised Beds Home

2018-11-28  The classic soil-based mix for a raised bed incorporates equal parts garden soil, compost and sharp sand. If your soil is a heavy clay, you can use perlite instead of sand to help lighten the soil. If your garden soil is sandy, however, a mixture of 1 part soil and 2 parts compost adds the extra organic matter necessary for your plants to thrive.
