Is Granite A Porous Rock

So porous rocks tend to be softer than non porous rocks.

Is granite a porous rock.

There are many ways to test porosity in a. Granite is a rock with interlocking grains. Igneous rocks range from the highly porous pumice to the nearly non porous granite. Granite is a porous natural stone.

Porosity or void fraction is a measure of the void i e. Alas its porous surface is granite s kryptonite. Like all natural stone granite is susceptible to liquid sinking into its surface. If liquid or stains get down into the stone it can result in damages and weakening of your granite.

Granite magmatic plutonic igneous rock which is hard compact and massive is not a porous rock in its original shape. For example limestone is very porous when compared to quartzite and granite isn t as porous as marble. This permeability allows air and water to enter into the rock body where physics and chemistry take over to explode the rock when it heats up. In some explosive eruptions of felsic magma as is the case with pumice the frothy mixture of rock and gas.

Strictly speaking some tests measure the accessible void the total amount of void space accessible from the surface cf. Sandstone is a rock with rounded grains. This means that if it is not properly sealed liquid is able to penetrate its surface. Empty spaces in a material and is a fraction of the volume of voids over the total volume between 0 and 1 or as a percentage between 0 and 100.

Also granite is immune from the damages of most common household acids. Some rocks are much more porous and permeable. Even worse germs bacteria and mold can invade unsealed granite counter tops with stains running not far behind. To better understand the natural porosity of granite it helps to understand the following details.

Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Granite is an igneous rock. It develops secondary porosity once it is deformed and altered in terms. Not all rock is as dense as the granite and marble we use to build with.

The general composition of granite includes silicon dioxide feldspar mica and various minerals.
