Armourstone is a generic term for broken stone with stone masses between 100 and 10,000 kilograms (220 and 22,050 lb) (very coarse aggregate) that is suitable for use in hydraulic engineering. Dimensions and characteristics for armourstone are laid down in European Standard EN13383. [1] In the United States, there are a number of different ...
ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm (0.079–0.248 in) for fine and 20–63 mm (0.79–2.48 in) for coarse. One cubic metre of gravel typically weighs about 1,800 kg (4,000 lb), or one cubic yard weighs about 3,000 lb (1,400 kg). Gravel is an important commercial product, with a number of applications.
0.001 t/m 3. The kilogram per cubic metre (symbol: kg·m−3, or kg/m3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]
Granodiorite (/ ˌɡrænoʊˈdaɪ.əraɪt, ˌɡrænəˈ -/ GRAN-oh-DY-ə-ryte, GRAN-ə-) [1][2] is a coarse-grained (phaneritic) intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar.

The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. [12] The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun , but was cheaper to mass produce and lighter, at the expense of accuracy. [ 12 ]
Density (volumetric mass density or specific mass) is a substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: [1] where ρ is the density, m is the mass, and V is the volume.
Boulder in British Columbia, Canada. Kämmenkivi stone on the Pisa hill in Kuopio, Finland. In geology, a boulder (or rarely bowlder) [1] is a rock fragment with size greater than 25.6 cm (10.1 in) in diameter. [2] Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely ...
