Definition
The specific gravity of fly ash is the ratio of the density of fly ash to that of a reference substance (Usually water).
This information can be used to tell whether fly ash will float (or sink) if dropped in water (Buoyancy).
Formula
SG = ρfly ash / ρwater
Note: Both densities need to be in the same unit as they will cancel each other and produce SG.

Specific Gravity vs Density vs Specific Weight
There are important differences between density, specific weight and specific gravity. Follow these links to learn about the differences between them.
I will provide you the fly ash specific gravity in a dimensionless unit (Unitless) in this page. You may check how it converts to kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/ft³ by following the link below:
Specific Gravity of Fly Ash (Relative to Water)
SG = 2.57 to 2.59
From this Source
SG = 1.9 to 2.8

Specific gravity values are not very useful. Why not check the density of fly ash (all units)?
