Stone

Stone is a construction material, which is obtained through a process performed in stonework where you get two forms of the material. One of these forms is rubbles, roughly broken stones bounded in mortar. And the other is the ashlar masonry : regularly cut blocks e.g. entablatures: **the upper sections of a classical order that rest on the capital of a column**. **The best bonds** ** of stone are **** those in which ** ** the vertical joints in one course are not about the joints in the course above and below. ** The disadvantages of this material are difficult to quarry, transport and cut, the weakness is in tension, is very expensive and is unstable whit load pushing at angles. But we can’t ignore the advantages this material their durability, adaptability to sculptural treatment and this material can be used naturally. **Thanks to the kindness of this material has been used since the construction of important architectural and archaeological works as Stonehenge in England to this time as a construction noble material (structural, masonry, coatings, etc.).** media type="file" key="Stone.wma" width="300" height="45"
