Stone

> Stones are mineral formations used in architecture and construction for it's high consistency. ** > Igneous, Sedimentary and Metamorphics. ** > They are hard, made of mineral accumulations, shapeable by cutting it, easy to find. ** > Because of it's high consistency.** > > > In this paragraph, i'm going to focus on stone's advantages and disadvantages when it is use as a construction material. The advantages of using stone like a construction material are it's ability to adapt to any scultural shape with the right treatment, apart from it's durability, and the fact, that it is used in it's natural **state**, among others. The disadvantages are that it is an expensive material, that it tends to give in with the tension, **so it limits it's use in lintels, beams and floor supports,** stone also gives in when loads are pushing at the wrong angles**, greek temples entablatures where made out of stone and they presented problems with the loads because of the angles they were pushing in, but in contrast with bricks, stone doesn't need strong bonds to have stability**; and despite of it's adaptability, stones are difficult to cut and to transport. **The cheapest mode of working with stone is rubble, that means breaking the stone in a rough way, in mortars, to make little pieces. The strongest rock used in architecture or construction is the ashlar masonry, which are rectangular well-cut blocks; they are prefered because of their weight and the presicion with which you can cut it and make the shape you want. The best way of working with stone is that in which they are place so their vertical unions aren't alined with the ones above and below. Stone has been used a lot since the stone age (Stonehenge, in England), it is used because of it's practical and natural expresion, despite of being replaced in some cases by cheaper structural materials.**
