Average density of granite.

5 it is strongly reduced in the presence of water. The density of granite is measured at about 2 6 2 7. This is measured either as a decimal between 0 and 1 or as a percentage. The exact chemical composition will vary greatly but there is an average chemical composition for granite.

In imperial or us customary measurement system the density is equal to 168 pound per cubic foot lb ft or 1 555 ounce per cubic inch oz inch. 1 1 4 inch 30mm thick granite weighs about 18 pounds 8 16 kg per square ft. There are a few things you can do to check the actual quality of granite as well as differentiate granite from marble and limestone. I use 2 75 as a good average.

What is the density of granite. Average density of the material for weight calculation will be shown in the density box with g cc as default unit. Granite solid weighs 2 691 gram per cubic centimeter or 2 691 kilogram per cubic meter i e. This number is typically expressed in terms of specific gravity.

Specific gravity is the density of the rock or mineral as compared to that of water. What is an average specific gravity for granite. Granite was created from cooling magma and lava as far back as 300 million years ago. Marble granite stone miscellaneous.

Porosity and density. In crystalline rocks like granite which have tight interlocking mineral grains porosity is normally quite low less than 1 percent. 1 cubic meter of granite solid weighs 2 691 kilograms kg 1 cubic foot of granite solid weighs 167 99364 pounds lbs granite solid weighs 2 691 gram per cubic centimeter or 2 691 kilogram per cubic meter i e. Density of granite solid is equal to 2 691 kg m in imperial or us customary measurement system the density is equal to 168 pound per cubic foot lb ft.

The average density of granite is between 2 65 and 2 75 g cm 3 165 and 172 lb cu ft its compressive strength usually lies above 200 mpa and its viscosity near stp is 3 6 10 19 pa s. Density of granite solid is equal to 2 691 kg m. Granitic rocks are considered to be felsic and as such have relatively low specific gravities most should fall in the 2 7 to 2 8 range. Quartz content can range from 10 60 while the feldspar content typically ranges from 65 95 and biotite content is around 10 15 in most granite.

This range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains. This natural raw material has been used by humans for thousands of years. 4 the melting temperature of dry granite at ambient pressure is 1215 1260 c 2219 2300 f. Granite grade is based upon the presence of soft minerals its origin thickness cut color and porosity.

3 4 inch 20mm thick granite weighs about 12 pounds 5 44 kg per square ft.
