BULK DENSITY This is a concept slightly different from the Bulking Factor CONCEPT. This is a measure of the WEIGHT of a given volume of material and is often expressed as an In situ or compacted weight versus a loose weight of stockpiled or otherwise uncompacted material.

When limestone is crushed, the particle size distribution becomes a significant factor in determining density. Smaller particles can pack more tightly together, resulting in a higher density compared to larger, more irregular fragments.

Bulking or swell factors for some materials: After excavation of 300 m3 clay with bulking factor 40% - the clay swells to. (300 m3) ( + 40%) / = 420 m3. in the dump. Soil and rock expansion - or swell - after mining.

Sedimentary rocks can have a wide range of densities, depending on the type of sediment and how well it is compacted. The following table provides a comprehensive list of density values for different rocks at standard room temperature (approximately 20°C or …

A typical density for crushed aggregate is around 1600 - 1800 kg/m 3 (100 – 112 lb/ft3) and the density of granite is 2520 - 2810 kg/m 3 (157 - 175 lb/ft3). Because the largest rocks are the ones that cause dents, the rock density is worthwhile considering.

Both the one and the other type of crushed stone is characterized by density - specific gravity, measured in kilograms per cubic meter. According to GOST, the true density is a material without air gaps, whose cubic meter weighs a certain amount of kilograms. Bulk - with air gaps left by loose stones. Gaps are caused by unevenness in the stone.

Typical effective density here ranges from 120 - 140 pounds per cubic foot (1.9 - 2.2 Metric Tons per cubic Meter). Solid Rock will be close to 150 - 170 pounds per cubic foot (2.4 -...

If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3. Even though sand is made of rock fragments, its density is less because the …
