  2. Limestone - Wikipedia

    en.wikipedia.org/wiki/Limestone

    The density of limestone depends on its porosity, which varies from 0.1% for the densest limestone to 40% for chalk. The density correspondingly ranges from 1.5 to 2.7 g/cm 3 . Although relatively soft, with a Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa . [ 13 ]

  3. Yule Marble - Wikipedia

    en.wikipedia.org/wiki/Yule_Marble

    This local geological activity resulted in a type of marble that is 99.5% pure calcite, with trace amounts of non-calcite inclusions (mainly quartz), and has a density of 170 pounds per cubic foot (2,700 kg/m 3). The non-calcite inclusions were caused through penetrations along the seams created by the dome uplift rather than through ...

    Monolith with bull, fox, and crane in low relief at Göbekli Tepe. The density of most stone is between 2 and 3 tons per cubic meter. Basalt weighs about 2.8 to 3.0 tons per cubic meter; granite averages about 2.75 metric tons per cubic meter; limestone, 2.7 metric tons per cubic meter; sandstone or marble, 2.5 tons per cubic meter.

    Given the local stone's density (which is limestone) stands at 2284 kg/m³, the d n50 is calculated to be 22cm. It may be observed that the stones in the sample appear much larger to the eye. This visual misperception can be attributed to a few particularly large stones within the sample, which distort the overall impression.

    Indiana limestone (also known as Bedford limestone) is a form of limestone used as a building material, particularly for monumental public structures. Some 35 of the 50 state capitol buildings in the United States are made of Indiana limestone, [ 1 ] as are the Empire State Building , Biltmore Estate , the Pentagon and National Cathedral in ...

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
