METHODS FOR THE DETERMINATION OF SPECIFIC GRAVITY Myles J. McDonough Chandler Engineering Company 2001 N. Indianwood Avenue Broken Arrow, Oklahoma 74012 HISTORY The terms Specific Gravity and Relative Density have been used for a number of years. Yet there seems to be some confusion over what exactly they mean.
The specific gravity of an object is the ratio between the density of an object to a reference liquid. Usually, our reference liquid is water, which has a density of 1 g/mL or 1 g/cm^3.
Feb 04, 2012· Specific gravity or relative density is the ratio of the density of the fluid to the density of water at standard temperature in example at 40C. Specific gravity can be determined directly from the density of a liquid as measured divided by standard density of water.

Specific gravity (sometimes referred to as Density) is a useful diagnostic attribute when trying to determine the mineral species of an unknown mineral specimen. But textbooks usually describe testing specific gravity using a laboratory balance scale that few of us have in our homes.
The specific gravity may be expressed as bulk specific gravity (OD), bulk specific gravity (SSD) (saturated-surface-dry), or apparent specific gravity. The bulk specific gravity (SSD) and absorption are based on aggregate after 24 h soaking in water. This test method is not intended to be used with lightweight aggregates.
The specific gravity of kerosine is 0.79 g/cc. How to Calculate Cement Specific Gravity? One can easily determine the value of specific gravity of cement using Le Chatelier Flask method. Determination of specific gravity of cement at the site level can be easily done using this is an experiment. Required Materials & Apparatus
Besides determining the displacement of water, specific gravity can also help determine if an object is going to float or sink in water. If the specific gravity of a substance is less than one, it floats in water, but if its specific gravity is more than one, it sinks.
