Read More20191217Relative density or specific gravity12 is the ratio of the density mass of a unit volume of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term relative density is often preferred in scientific usage. It is defined as a ratio of density of
Read MoreThe formula for specific gravity given that the reference substance is water is the density of the object divided by the density of the water. Here we use the Greek symbol Rho to indicate density.
Read MoreWater is used to determine Specific Gravity. The density or more precisely the volumetric mass density of a substance is its mass per unit volume. Density Mass Volume. Specific gravity is the density of a substance divided by the density of
Read MoreThe specific gravity of portland poolana cement is 3.15. The specific gravity test can be done on cement using the bottle method. In this method instead of water kerosene is used to test the
Read MoreThe 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 ammonium nitrate has a specific gravity sg of 0.73 while dry ammonium sulphate has a sg of 1.13 1130 kilogramscubic meter.
Read More2014414Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water at a temperature of 73.4F 23C has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.
