Testing procedure. The Specific Gravity is computed as the ratio of the weight in air of a given volume of soil particles at a stated temperature to the weight in air of an equal volume of distilled water at the same temperature. The procedure that is followed towards that goal is the following: Weigh the empty and clean volumetric flask (W 1).

The gravity method is a relatively cheap, noninvasive, nondestructive remote sensing method that has already been tested on the lunar surface. It is also passive – that is, no energy need be put into the ground in order to acquire data; thus, the method is well suited to a populated setting such as Taos, and a remote setting such as Mars.

Discussion: Basically, specific gravity is the ratio of the weight of a given volume of material to the weight of an equal volume of water. However, there are several variations of this definition depending upon the material and purposes for which the value of specific gravity is to be used. In concrete work, the term specific customarily refers to the density of the individual particle, not ...

A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements. Data can also be used to better understand the relationship between aggregates or blends and to predict trends during production.
