#67 Limestone Gravel Stone is a crushed angular Limestone aggregate. Sizes of #67 Stone range from 1/2" - 3/4". It is more uniform in size and a little smaller than the #57. However, it is so similar in size that it is often substituted with #57. The #57 and #67 are very commonly used interchangeably.

AASHTO T 85 and ASTM C 127: Specific Gravity and Absorption of Coarse Aggregate; Background. Specific gravity is a measure of a material’s density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at a temperature of 73.4°F (23°C) has a specific gravity of 1.

Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at, typically, 4 Celsius. Density is an important characteristic of a rock, since this parameter helps to identify the rock type and its geologic structure.

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn''t as complex as you may think because water''s density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

bulk specific gravities of crushed aggregates and cylindrical rock cores from six limestone quarries, one slag, one crushed trap rock, and one synthetic aggregate (Synopal) were determined by five methods. The methods are standard ASTM, geometrical measurement, mercury dis placement, and two chemical indicator methods proposed by the authors.

Measure the increase in volume caused by the dry solids displacing some of the water. Assume the new volume is 550 c.c. The displacement, then, is 50 c.c. (550-500). Divide the weight of the dry solids (200 gr.) by the difference in volume (50 c.c.). The result, 4.00, is the specific gravity of the dry solids.
