granite floors

In modern construction, granite is widely used, especially for floors, both indoors and outdoors, and for outdoor facings. Its high resistance to acids makes it adequate for the construction of monuments. Granite can be polished, something that is usually done when it is used indoors; or it can be flame-hardened, which is preferable when it is used outdoors (also because this treatment makes it non-slippery). Since it is a highly resistant material, it is often used for city-square and public-area pavings.
