Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC However it is well recognize that physical chemical and thermal properties of aggregate substantially influence the properties and performance of concrete

x Specific gravity Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance In most of the cases the reference substance is water for liquids or air for gases Specific gravity represents a

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density no matter how small or large the fraction is For example beryllium has a specific gravity (sg) of 1 84 (1840 kg/m) As specific gravity is just a comparison it can be applied across any units

AASHTO T 84 - Standard Method of Test for Specific Gravity and Absorption of Fine Aggregate 16 AASHTO T 85 - Standard Method of Test for Specific Gravity and Absorption of Coarse Aggregate 17 AASHTO T 100 - Standard Method of Test for All NYSDOT listed references are available from the New York State Department of Transportation

Pure water was chosen as the 'base line' for specific gravity and given the value of 1 The specific gravity of all other materials are compared to water as a fraction heavier or lighter density For example beryllium has a specific gravity (sg) of 1 84 (1840 kg/cu m) (see table below)

25-10-2019Specific gravity has no units because it's a ratio of density divided by density so all units cancel out Therefore the specific gravity of gold is simply 19 3 Anything with a density greater than 1 000 sinks in pure water at 4 degrees Celsius and anything with a density less than 1 000 floats

Coarse particles on a river bed are left behind as terraces when a river case the soil particles - the specific gravity is equal to the mass of the dry soil particles divided by the mass of water they displace the vertical effective stress at the base of the column of sand in its loose dry state (b)

Fine aggregate is used in many fields in sites for many purposes So the determination of specific gravity of fine aggregate is very essential Specific gravity of fine aggregate can be defined as the ratio of the weight of given volume of coarse aggregate to the weight of given volume of distilled water
