Albedo Of Granite

It is well known that it is particularly high on reflective or white surfaces for example snow.

Albedo of granite. The albedo of different surfaces. Table 1 the approximated ranges of albedo of natural surfaces natural surface types approximated albedo blackbody 0 forest 0 05 0 2 grassland and cropland 0 1 0 25 dark colored soil surfaces 0 1 0 2 dry sandy soil 0 25 0 45 dry clay soil 0 15 0 35 sand 0 2 0 4 mean albedo of the earth 0 36 granite 0 3 0 35 glacial ice 0 3 0 4. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Gray type i ii portland cement left albedo 0 32 and white type i portland cement.

Sri measures the roof s ability to reject solar heat defined such that a standard black reflectance 0 05 emittance 0 90 is 0 and a standard white reflectance 0 80 emittance 0 90 is 100. Incorporates both solar reflectance and thermal emissivity in a single value. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Level 1 granite has a very simple design and the colors are standard.

The amount of incoming radiation which is reflected from the earth albedo has an important bearing on the earth s response to climate change. The measure for this is the albedo which also provides information about how much a surface warms up. Learn more about the properties and uses of granite in this article. The albedo of dark coloured wet and very rough soils ranges between 0 05 and 0 15 while the albedo of light coloured dry and smooth soils varies between 0 35 and 0 40 dobos 2006.

This stone comes in a seemingly endless amount of granite colors and styles for you to choose from. High albedo pavement ha scenario. A low grade granite slab is a thinner cut usually about 3 8 inch it usually requires a piece of plywood backing for more strength. The current situation pavement is composed of granite with albedo of 0 4.

You are practically guaranteed to find something that you like when looking for granite countertops or other home fixtures. Light granite scored best in the measurements during the 6 months of testing. Granite is a highly attractive durable and easy to care for stone that will transform your home for the better.
