Stone

There are different types of stones such as magmatic, sedimentary and metamorphic. Depending on the type of rock, the texture is going to change but they have a common characteristic: they are solid. I think stones are used in constructions because they are the strongest material to work with and the one that will last the most.
 * Stones are a geological formations composed by minerals.

Stones are a construction material that have been favored over other materials for monumental architecture. There are different uses for stones such as rubble and ashlars masonry, among others. Rubble is mortar-bounded broken stones with an irregular size, shape and texture, and ashlar masonry is the dressed stones with a regular shape, cut in rectangular blocks, used in constructions as an alternative to bricks. We can find advantages and disadvantages about stones. Some of the advantages are their durability, adaptability to sculptural treatment and that they’re used naturally. On the other hand, we have some disadvantages, these are that stones are difficult to quarry, transport and cut, they are expensive, they have weakness in tension and they are unstable with loads pushing at angles, they also will require changes or an industrialization treatment and labor to work with this material. Some rock types are more commonly known as granite, limestone, marble, travertine, quartz-based stone (sandstone, quartzite) and slate. Other varieties of dimension stone that are normally considered to be special minor types include alabaster (massive gypsum), soapstone (massive talc), serpentine and various products fashioned from natural stone. In conclusion, when we talk about stones, we are talking about a strong material that has many different uses. And really it doesn’t matter what the use is, it is guaranteed that it’s going to last. ~media type="file" key="andrea stones.mp3"
