Density is defined as mass per unit volume. If the hydrometer rests on the bottom of the container, you will not get an accurate reading. Density is the weight per unit volume of material at 23C and is expressed as D 23C in g/cm 3. Good soils are dense, well-graded gravel, gravelly sands, silty gravel, over-consolidated clays, and rock. Posted November 17, 2021. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Material Properties - Material properties of gases, fluids and solids - densities, specific heats, viscosities and more. Mainly Specific Gravity is the is the ratio of the density of a substance to the density of a reference substance at a fixed temperature. Therefore, by definition, water at 73.4F (23C) has a specific gravity of 1. Which is mainly the ratio of the weight of the given volume of aggregates to the weight of an equal volume of water. The specific gravity of aggregates normally used in construction ranges from about 2.5 to 3.0 with an average value of about 2.68. Bulk Density and Specific Gravity Chart: S .
