stones

====**Stones are a material, known as rocks also. ** ==== ====**I don’t know exactly how many, but I have seen a lot. Everyone can find stones in nature, we see them very often, but I also have seen stones used for construction, decoration, kitchens, floors, bathrooms and more. ** ==== ====**Stones are easy to found because are one of the most common materials in nature. They are hard, the have durability, and they can be shaped. They are also very heavy. ** ==== ====**I think because they are very hard and they can adapt to a lot of situations as I said before. ** ==== ====**When they are combined with other materials they make a rigid structure that has durability, and they can also be used for decorative purposes. ** ====

Stones, as any other materials have advantages and disadvantages. Their advantages include durability, adaptability to sculptural treatment and the fact that they can be used naturally. Some of their disadvantages are their difficulty to be quarried, transported and cut, their weakness in tension and their price, what means that they are expensive.


 * Stone was used mostly for monumental architecture and the type of rock that was used for it is ashlar masonry, because it's the strongest and the most suitable, it's also the most stable kind of rock and it's cut regularly, usually rectangular pieces of it . On the other hand, the cheapest and simplest type of stonework is rubble.

According to teacher Dafne Gonzalez, the best way of stone and brick bonding is that in which blocks are placed on a way which vertical joints in one course are not aligned with the ones above or bellow.

The podcast also mentions that stone has been use since the stone age and also by the Egyptians and Syrians. media type="file" key="STONE RECORDING.wma"

2 statements of comparison and contrast -“Stone masonry, in contrast with brick, does not depend on strong bonding for stability” -“The best stone (and brick) bonding is that in which blocks are placed so that the vertical joints in one course are not about the joints in the course above and below, since the stone resists deformation better than any bonding material”

2 statements expressing cause and effect

-The weight creates problems of stability when loads push at an angle - Because of its weight and the precision with which it can be shaped, stone masonry (in contrast with brick) does not depend on strong bonding for stability.
