=**//Materials review. //**=



As I could see through all the readings and postcastings, there are too many different materials for construction like brick, stone, concrete, steel and iron; each one of them with its advantages and disadvantages. Some materials are cheaper than others, some are weak in tension or compression or both, there are some easy to transport and some too heavy for be easy to do it.

The stone is the oldest material of construction and the easier to work with. Steel is the strongest in tension and compression. Bricks are made of clay and they are easy to mold into any shape and size, iron can be shaped too but it breaks without warning and it is expensive. Concrete has the advantage that is fireproof and waterproof nevertheless it cracks with temperature changes.

In conclusion, there are a variety of materials for construction but whoever is going to work with them have to keep in mind all the advantages and disadvantages of each one and choose the one that covers all the needs of the construction.
