The void ratio of a mixture of solids and fluids (gases and liquids), or of a porous composite material such as concrete, is the ratio of the volume of the voids filled by the fluids to the volume of all the solids ().

2023年4月26日 · The void ratio may be defined as the ratio of the volume of voids to the volume of the solid. It is generally denoted by e. Mathematically, e = Vv / Vs where, Vv = Volume of voids Vs = Volume of the solid a.

2013年12月16日 · The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids. The void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction. Void ratio and porosity differ only in the denominator.

Void ratio of a soil sample is defined as the ratio of the space occupied by the voids i.e. volume of voids to the space occupied by solids i.e. volume of solids.

Void ratio is a fundamental concept in soil mechanics that quantifies the relationship between the volume of voids and the volume of solid particles in a soil sample. It plays a crucial role in understanding soil behavior, strength, and compressibility.

Here, you are going to learn how to calculate the moister content, void ratio, and degree of saturation of the soil by using the formula for void ratio, degree of saturation, etc.

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 ...

2022年5月7日 · It is the ratio of the volume of air voids Va to the total volume of the soil mass (V) and is expressed in percentage. Mathematically, na = ( Va / V ) x 100.

2018年7月27日 · By the definition of porosity, we have, n = Vv/V. Where, Vv = Volume of voids in a given soil mass. V= Total volume of the soil mass = Volume of voids in the given soil mass (Vv) + Volume of soil solids in the given soil mass (Vs). Thus, n = Vv / (Vv + Vs) Or, n = 1 / (1 + Vs/Vv) [Both sides diveded by Vv]

Void ratio refers to the ratio of the volume of empty space to the volume of solid particles in a soil mass. You might find these chapters and articles relevant to this topic. Daniel Hillel, in Encyclopedia of Physical Science and Technology (Third Edition), 2003.
