===Over the past 7 weeks, we've been studying in class the different construction materials, and personally I've learned a lot about them, I now understand that stone is better used in decoration, like chimenys and fences, stone is produced by the mixture of Vulcan lava and sea water, then as the time passes and erosion and other natural effects moved this pieces apart, the stone began to take part in the environment. A brick is a block of ceramic material used in masonry construction, usually laid using mortar. They're made of differet things, there are mud bricks, dry pressed bricks, fly ash bricks, calcium silicate brick, among others. Bricks are mostly used for building and pavement, also brik is used in the metallurgy and glass industries for lining furnaces. For example, in the United Kingdom, bricks have been used in construction for centuries. Steel is one of the strongest materials used in construction but iron molds to any shape, also steel is very strong in both compresion and tension, and so is iron. The thing about this two is that steel rusts and can lose its strenght in high temperatures but iron breaks without warning. Regarding the advantages and disadvantages iron and steel are a big part of the world of contruction. Concrete is a manufactured mixyure of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination to a stonelike, water and also fire resisting solid of great compressive but low tensile strenght. There are different types of concrete. Reinforced concrete was developed to add the tensile strenght of steel to the compressive strenght of mass concrete. Glass generally refers to hard, brittle, transparent materials or amorphous solids, such as those used for windows, many bottles, or eyewear. Glass plays an essential role in science and industry. The optical and physical properties of glass make it suitable for applications such as flat glass, container glass, optics and optoelectronics material, laboratory equipment, thermal insulator (glass wool), reinforcement fiber (glass-reinforced plastic, glass fiber reinforced concrete), and art. Wood is with stone one of the oldest construction materials, given that its easily found in the nature its composition assures a higher level of resistance to both compression and tension, so it is oftenly used to build houses, etc. except for the foundations because these are suceptible to fire, and termites too. But as everything in life, it doesn't last forever for it's not uniformly strong, it contains moisture and things that make wood suceptible in different climates, so it has to be carefully selected for different constructions. And in resume, each one of these materials are necesary for the construction industry, although I do prefer wood, because of the environmental problems we-ve been having as a civilization, so becoming more concious, for me, is using wood.===
