2.Steel is a metal alloy of iron and carbon and often other alloying material in its composition to make it stronger and more fracture-resistant than iron. Stainless steels resist corrosion and oxidation because of the additional chromium in their make-up. Because it is so strong compared to its weight and size, structural engineers use it for the structural framework of tall modern buildings and large industrial facilities. Some of its qualities include: 1. Steel has high strength-to-weight and strength-to-size ratios. 2.Concrete is a composite material made of fine and coarse aggregate (think gravel, crushed stone, recycled concrete, and geosynthetic aggregates) bound together by a liquid binder such as cement that hardens or cures over time. Portland cement is the most common type of cement, and is a fine powder, produced by heating limestone and clay materials in a kiln and adding gypsum. So Portland cement concrete consists of the mineral aggregate, bound with Portland cement and water. After mixing, the cement hardens or
Explanation:Among the oldest, or perhaps theoldest, of building materials, woodhas been used for thousands of years and has properties that make it an ideal building material—even in the days of engineered and synthetic materials. For construction use, wood pieces are machine-planed and cut into standard dimensions, such as 2”x4” (1.5”x3.5” actual) and 2”x6,” (1.5”x5.5” actual) so that their measurements can be accurately factored into building plans—this is known as dimensional lumber. Wood in larger sizes is usually referred 2.The longest lasting building material available is the one that’s been here for thousands of years: stone. In fact, the most ancient of buildings still in existence in the world are made of stone. It has many advantages, though engineers and architects must make some special considerations when planning a building using stone. 1. Dry stone walls made of dense rock have been used for thousands of years. Different forms of mortar were later used to hold them together. 2. Because it is so dense, stone can be
