How does the specific gravity of a material is related to the strength of that material?

see specific gravity that means in a simple word ratio between unknown material density to standard material density. for us standard material is water.
in strength of material when we calculate deformation for self weight then basically we need to find out the weight
so weight = mass * gravity
mass = density of material * volume
density of material = specific gravity * density of standard material
in this way specific gravity is relate with SOM.
as well as when we find the deal load then we do
dead load = unit weight * volume
unit weight = density * gravity
density = specific gravity * standard materiel density.

If you mean in general, then no. The strength of any material doesn’t depend on the specific gravity of that material, be it a solid or paste.
Neither of the compressive, tensile or shear strength depends on density. For example, two grades of steel might have the same specific gravity but very different strengths. Cast iron is stronger in compression and wrought iron in tension despite the same densities. You can design two concrete mixes with the same densities and compare the strengths to check yourself!
