Specific gravity is a concept that we all have seen but do not know its name. Also, the density of the object determines this factor. Moreover, in thi9s topic we will discuss specific gravity, specific gravity formula and its derivation and solved examples.
Specific 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.

Color/Appearance Heartwood is a light to medium brown, commonly with an olive cast. Paler sapwood is not always sharply demarcated from the heartwood. Quartersawn sections display prominent ray fleck patterns (see images below). Red oak (Quercus rubra) tends to have a slightly redder cast (as opposed to olive), but color alone isnt always a reliable method of determining the type of oak.

Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.
