Exp 2: Week 2 Independant Study

3 Selected Materials

Concrete

Concrete is a composite material composed mainly of water, aggregate and cement. When these ingredients are mixed together, they form a fluid mass that is easily molded into shape.  Over time, the cement forms a hard durable material with many uses.  Concrete is extremely beneficial to us, in not only one way in several ways such a roads, buildings, structures, practically its everywhere.  Modern buildings are usually engineered to last 70 plus years.

Glass is a very useful material but at the same time very fragile and lack of temperature control. Glass has been very helpful to us allowing our buildings to get natural sunlight.  All up it’s a very helpful material in our livelihood.

Week 2: Lecture Reflection

In this weeks lecture we were shown work of students from the past.  We also discussed different kinds of materials and how they are used in the world we live in today. Along with that we were shown how concrete is made and how they are formed. This was particularly interesting to me because i got a better understanding of the process.
