Acid Vs Marble

However sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled peeled off in some places revealing crumbling stone beneath.

Acid vs marble.

Being composed of calcium carbonate marble will react in contact with many acids neutralizing the acid. Finish options for marble and quartzite. An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. Marble has a moh s hardness rating of about 3 while quartzite has a rating of approximately 7.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. It is one of the most effective acid neutralization materials. Particularly on older concrete slabs exposed to the elements the variable porosity of the slab allows the stain to penetrate to different depths creating natural areas of light and dark staining. This black crust is primarily composed of gypsum a mineral that forms from the reaction between calcite water and sulfuric acid.

Marble and quartzite can be finished in a variety of ways. However concrete acid stain possesses the unique property of creating a marble like effect without any additional staining techniques. Quartzite is quite different. Comparing costs the price of marble and limestone can vary dramatically based on the color source and treatment of the stone.

For example while you can use phosphoric acid on ceramic porcelain and composite surfaces you should never attempt to use it on natural marble onyx granite or limestone. Marble is often crushed and used for acid neutralization in streams lakes and soils. Stone surface material may be lost all over or only in spots that are more reactive. The hardness of marble vs.

This acid etching can only be removed by professionally resurfacing and rehoning the stone. This means that marble is much softer and will scratch easier than quartzite.
