Research Materials:
Concrete:
Concrete is a material composed mainly of water, aggregate, and cement. Additives and reinforcements are added in the mixture to achieve the desired physical properties. When these ingredients are mixed together, they form a fluid mass that is easily molded into shape. The expected lifetime of concrete usually lasts for 100 years. Concrete can be damaged by many processes, such as the expansion of corrosion products of the steel reinforcement bars, freezing of trapped water, fire or radiant heat, aggregate expansion, sea water effects, bacterial corrosion, leaching, erosion by fast-flowing water, physical damage and chemical damage.
Glass:
Glass is traditionally formed by rapid quenching and under-cooling of a liquid, forming a super-cooled liquid which solidifies at its glass transition temperature. The expected lifetime of glass varies on the types of glass, the expected range is between 27-34 years. Since glass are fragile objects it could be broken by asserting a large force towards the glass with any hard objects.
Steel:
Steel is an alloy composed of iron and carbon. Steel is made from smelting iron ore to become ingots, then the ingots are heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. The typical life expectancy of steel is usually around 83 years. Steel can be damaged by long-term exposure of air molecules, long-term exposure to wet elements, sea water effects, bacterial corrosion, physical and chemical damage.

Reflection:
This week we went through some of project one submission and we also went through some properties of materials e.g. concrete and the production process of these materials. Since I chose Church of Light and it is mainly composed of reinforced concrete I found this week's lecture really useful.
