Stone

** Stone Paragraph ** It is a material used for construction because it has some advantages such as: its durability and resistance to different situations like earthquakes, case of fire, weather changes and so on, also it can be adaptable to different sculptural treatments like arches and bridges giving the opportunity to create not only basic forms, and we don’t need to give it special treatments or chemistry process because it is used just like we find it in nature. Stones can be worked by two different forms, like rubble with irregularity forms and by ashlars for more compact constructions; because for their weight and precision they can be easily shaped. To guarantee a better connection between two or more stones the use of mortar is the best option, also we can mix different types of stones used in a wall such as Cap Stones, Tie Stones and complete it with Rubble fill. It is well known that stones were the first material used for constructions and a big prove of its resistances and durability can be appreciated when we visit those places that were constructed in the prehistory such as Stonehenge and one of the seven wonders of the world: the Egypt pyramids. But at the same time it presents some disadvantages like the next three things that make it work harder: extraction, transportation and fragmentation. All of them require special machines to make those heavy works. Also we need to be careful with which is the most appropriated form to organize them to prevent accidents; otherwise the construction can be fragile and unstable. It is recommended to alter the vertical joints to provide more stability media type="file" key="stone.wma" width="300" height="45"
