Is there any relationship between the bulk density and density of soil, and the weight and density o

Dry bulk density = dry density.

Multiply by 10 dry bulk density, a construction engineering term.

It refers to the bulk density in the state of no moisture.

It is generally used to represent the compaction effect of soil, and the larger the dry bulk density, the better the compaction effect.

Maximum dry bulk density, the highest dry bulk density obtained in the laboratory.

The concepts of "bulk density" and "density" are theoretically the same, but the environment in which they are applied is different

1. The bulk density is generally the weight of one cubic meter used in engineering, that is, the weight of the object in the unit volume. Density has a wide range of applications, that is, "mass per unit volume of substance", liquids, solids, and gases can be used.

Modification and supplement: 2. The bulk density is also indicated.

The gravitational properties exhibited by an object due to the gravitational pull of the earth, and for homogeneous fluids, bulk density also refers to the gravitational force acting on a unit volume. Some books use it to denote . In the International System of Units, the unit is: the cattle cubic meter.

For example, under standard conditions, the bulk density of air is Ox cubic meters, and its density is kilogram cubic meters).

3. The two quantities are = numerically

Approximate calculation = 10, but the traditional units are different.

4. There are specific volumes and specific gravity of similar quantities (no longer used).

The density of the soil is the bulk density of the soil. Bulk density is the weight of the sample at a certain capacity. But pay attention to unit conversion.

The gravity of the soil. It is density multiplied by acceleration. The unit of density is kg m and the unit of acceleration is m s, which is multiplied by the severity (kg*m s) m.

The unit n of force is calculated according to f=ma, that is to say, 1n=1kg*ms, and finally there is the unit of gravity nm, and the larger unit of gravity is kn m, and 1kn m = 1000n m.

Corresponding to the above densities, the natural weight, saturated weight sat and dry weight d are used to represent the unit volume of soil in different water content states.

weight. Numerically, they are equal to the corresponding density multiplied by the acceleration due to gravity.

g。In addition, the heaviness of the soil in still water is equal to the saturated gravity of the soil minus the heaviness of the water, which is called buoyancy.

Since there is a g = mg relationship between the weight (g) and the absolute mass (m), the relationship between the gravity of the soil and the density r of the soil is as follows: r g = ( 1-8 ) where g is the acceleration due to gravity.

The density of the soil is different, and the weight is different. When the density of the soil is g cm3, the weight of 1 cubic meter of soil is about tons, and the weight of 1 cubic meter of saturated clay is about tons. To claim the weight of the soil, it is calculated according to the product of the soil density, mass equal to volume and density (m = p v).

Cohesive soil is a soil with more clay particles and less permeability. It has good water stability, high strength and large capillary action after compaction. Its particles are fine, the pores are small and many, the water permeability is weak, it has the characteristics of expansion and contraction, and the mechanical properties change with the water content.

Soil bulk density, also known as soil false specific gravity, is the quality of dry soil in the undisturbed soil per unit volume, undisturbed soil is the soil without compression or expansion disturbance, including the volume of air and water, generally use a small hammer to drive the ring knife into the soil, the chain knife with the soil dug out, cut off the excess soil with a knife, seal the two ends of the ring knife, bring it back to the laboratory for analysis, and use the 105 drying method to measure.

Soil density, also known as soil particle density, is the drying weight per unit volume of soil, the volume of which does not contain air, and it is generally considered that its value is the range is, the mass of solid particles per unit volume, in grams of cubic centimeters.

The relationship between bulk density and density of soil is that the total porosity of the soil can be calculated from the data of soil density and soil bulk density. Soil bulk density and soil density are similar, and they do not need to be calculated against each other, as long as the unit conversion is done.

Formula for calculating soil bulk density:

Soil bulk density is determined by the number of soil pores and soil solids. The weight of any unit of soil can be calculated based on the bulk density of the soil. The formula is: soil weight = volume bulk density.

Soil bulk density should be called dry bulk density, also known as soil false specific gravity, the ratio of a certain volume of soil (including soil particles and pores between particles) after drying to the volume before drying. (Soil moisture varies from time to time due to factors such as evaporation, especially when the seasons change.) Therefore, the quality of wet soil per unit volume does not have complete reference significance, so the accurate name of soil bulk density should be dry bulk density, also known as soil false specific gravity).

The bulk density of soil is density, which is obtained through the process of compaction, drying, and weighing.

Sandy clay scale maximum dry density.

The bulk density of soil is the density, which is obtained through the process of compaction, drying, weight and other processes, and the volume is the volume of an object to accommodate another object is called volume. If it is the volume of soil? What does he tolerate? Water? Air? Impurity?

Actually, the two formulas are the same.

However, when the "moisture content" in the two formulas is substituted into the data, the "moisture content" in the formula "dry density = wet density (cultivation and distribution 1 + moisture content)" should be expressed as a percentage, and the "moisture content" in the formula "dry density = wet density (1 + moisture content)" should be expressed as a fraction.

The ratio of the weight of a certain volume of soil (including soil particles and pores between grains) after drying to the weight of water in the same volume. It is the same as the bulk density of the soil, which is expressed in grams by the weight of 1 cubic centimeter of dried soil including pores, and is sold at the same value.
