Why is relative density not used for clays?

Relative density has no real influence on the soil’s performance, its range of application does not span across all soil types, and it is subject to large inherent errors that make its use a technical risk. Relative density is a definition rather than an inherent property of the soil.

Can relative density of soil negative?

Negative values of relative density usually result if the layers of uniform soils are mixed together. The trends of the data indicate that alluvial soils have relative densities which range from 20 to 70%. The data indicate that some uniform gravel alluvium can have lower relative densities than the sand.

Can relative density of soil be greater than unity?

Hence porosity itself does not indicate whether a soil is in loose or dense state. For very dense gravelly sand, it is possible to obtain relative density greater the one. This means that such natural dense packing could not be obtained in the laboratory.

What is relative density explain with example?

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink.

Is code for relative density?

Test to determine the Relative Density of Soil. The test procedure is based on IS 2720(Part 14): 1983; Determination of relative density or density index of cohesionless soil.

Can you have a density of zero?

It can be a positive or negative. In case of standing alone graphene, there are no density of states at Ef = 0, which leads to a zero transmission coefficient and high resistance.

What is soil relative density?

Relative density is the measure of compactness of cohesionless soil. Relative density or density index is the ratio of the difference between the void ratios of a cohesionless soil in its loosest state and existing natural state to the difference between its void ratio in the loosest and densest states.

Why relative density has no unit?

Since relative density is a ratio and we know that ratio of two quantities is unitless, hence, relative density has no unit. Answer: relative density = density of substance / density of water. As it is a ratio and both the physical quantities in numerator and denominator are the same, it does not have any units.

Can we use hydrometer to measure density of milk?

Correct Option: B. Lactometer is used for measuring the density (creaminess) of milk. It is essentially a hydrometer which is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water.

Why relative density have no unit?

Relative density has no unit because it is the ratio of same units which gets cancelled. Answer: As both the numerator and the denominator on the RHS of the above formula has the same unit (i.e. kg/m3) they get cancelled. Hence relative density has no unit.

What do you mean by 0 density?

Density is defined as Mass divided by Volume. Matter has mass so mass requires volume. If there is no Mass it occupies no volume. Therefore if there is zero mass of a substance there is zero volume. So the data point (0,0) is the starting point for all density graphs regardless of the substance being studied.

Can the density be negative?

There can not be less than zero charge, therefore charge density can not be negative.
