What is Building material?
'''Building material''' is any [[raw material|material]] which is used for a [[construction]] purpose. Many naturally occurring substances, such as [[clay]], [[sand]], [[wood]] and rocks, even [[twig]]s and [[leaves]] have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less [[synthetic]]. [[Brick]]s are man-made, and so is [[plaster]], [[concrete]], [[stucco]] and many other materials. However, they are usually still made out of natural materials, bricks being a good example. They are based on [[clay]]. [[Steel]] is based on natural types of [[iron]]. One example of a man-made imitation is [[scagliola]], which can imitate more expensive natural materials such as [[marble]]. {{stub}} [[Category:Building materials]]
