How does specific gravity and bulk density differ?

Specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. Bulk density is weight of a unit volume of a material to the same volume of water including voids.

What is the difference between density and specific gravity of cement?

Density is defined as mass per unit volume. It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3).

What is the relationship between specific gravity and density?

Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material, often a liquid. If a substance’s relative density is less than one then it is less dense than water and similarly, if greater than 1 then it is denser than water.

What is difference between specific weight and density?

The density of the material is defined as mass per unit volume, typically measured in kg/m3. The standard gravity is acceleration due to gravity, usually given in m/s2, and on Earth usually taken as 9.81 m/s2. Unlike density, specific weight is not a fixed property of a material.

What is the bulk density of cement?

1440 kg/m3
The Heavy Mortar has bulk density more than 1500 kg/m3. Lighweight Mortar: It is prepared from light weight sand. The lightweight mortar has bulk density less than 1500 kg/m3….

Can you convert specific gravity to density?

Converting a specific gravity into a density is as simple as multiply the SG by the reference density for which it was based. In most cases, this is the density of water, and therefore your multiply the SG by 1 to yield your density in g/cm^3.

Why it is important to determine the bulk density?

Why it is important: Bulk density reflects the soil’s ability to function for structural support, water and solute movement, and soil aeration. Specific problems that might be caused by poor function: High bulk density is an indicator of low soil porosity and soil compaction.

What is the bulk specific gravity?

Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume of gas-free distilled water at the stated temperature.

Where specific gravity is applicable?

Specific gravity can be used to determine if an object will sink or float on water. The specific gravity of water is equal to one. If an object or liquid has a specific gravity greater than one, it will sink. If the specific gravity of an object or a liquid is less than one, it will float.

What is the difference between density and specific gravity?

Density means Bulk density. It can be defined as weight of cement per unit volume. That is, it can weigh 1.44 g per cubic cm of volume. This volume of cement contains lot of pore spaces. Specific gravity is also a measure of density relative to water.

What is the specific gravity of sugar and cement?

The value of the actual density of sugar is around 1.2 g/cc. Now specific gravity is nothing but the ratio of density of the substance to density of water. Since density of water is considered as 1 g/cc, the specific gravity of sugar has the same value of 1.2 without the units. Coming to the case of cement, the concept is similar.

What is the weight of cement per unit volume?

It can be defined as weight of cement per unit volume. That is, it can weigh 1.44 g per cubic cm of volume. This volume of cement contains lot of pore spaces. Specific gravity is also a measure of density relative to water. But, it focuses on particles rather than whole as a volume.

What is meant by bulk density of a material?

Bulk density of any material is the weight of PARTIALLY COMPACTED material per unit volume. Bulk density of material is not equal to it’s specific gravity as specific gravity is weight of FULLY COMPACTED material per unit volume.
