Is Marble Porous And Permeable

The emphasis is on the inter relationships of these properties but a number of reported.

Is marble porous and permeable.

Permeability requires that these pores be interconnected and. Porosity and absorbency varies in marble but we are very aware that fluids can be absorbed as marble tops are very easy to stain. This term refers to the amount of void spaces in the stone that allow liquid and air to pass through. In contrast metamorphic stones like marble and slate have higher porosity because of the re crystallization process.

Smooth cool beautiful as a diamond and much more resistant to porosity problems marble is a gem of a counter top surface. Marble like most stone tiles has high maintenance requirements. Never set your drink down on a marble surface it will leave a ring and wipe up any spills immediately as they can stain or etch marble s porous. Quartz is a non porous material.

Article osti 6116963 title porosity permeability and their relationship in granite basalt and tuff author abstractnote this report discusses the porosity storage and permeability of fractured mainly crystalline rock types proposed as host rock for nuclear waste repositories. Not all rock is as dense as the granite and marble we use to build with. Some rocks are much more porous and permeable. Are quartz countertops porous.

In the case of marble which is metamorphic as well as sedimentary porosity can be considerably higher when compared to granite up to 2 percent. In terms of natural stone countertop options materials like granite are on the less porous side whereas a material like limestone is very porous. Marble is also fairly porous but not as much as limestone and sandstone. 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.

No microcracks initiate or propagate during the tests and the variation of permeability is due to the change of aperture of microcracks. The crystals within the stone spread out and arrange themselves which causes pores to materialize amidst the grainy material of the stone. Still marble is more porous softer and less durable when compared to granite. Staining is also a problem with more porous stones especially darkly colored liquids like red wine.

It must be sealed and cleaned regularly. As previously mentioned granite is of an igneous nature which makes it less porous than sedimentary rocks such as limestone and travertine. The permeability of intact marble samples collected from the depth of 1 6 km in southwestern china is investigated under moderate confining pressures and temperatures.
