Week 2: Reflection
The variety of programs used in this course and especially in this second project will be beneficial in future activities perhaps in animation or a similar virtual set design type of assignment. Software used is interesting and I didn't know work could be integrated across various programs. I think this will be helpful in other courses that have a heavy influence on computing and using different software. This course allows a lot of self-direction which gives space for creativity and individual approaches.
Week 2: 3 Materials
Choose three materials and do some research on their properties, i.e. the process of making each material, how long they will last, what makes them corrode, structural pros and cons, what these materials are typically used for, environmental impacts.
CONCRETE
Paste: limestone + clay + gypsum + various other chemicals and minerals = cement. These materials are crushed, mixed in appropriate proportions, burned and ground. Resulting mixture is combined with water where a chemical process called hydration takes place, and the resulting paste dries into a solid stone-like mass.
Cement, water and aggregate measurements have a huge influence on concrete's strength, permeability and durability.
Lifespan: depends on iron and steel bar reinforcement inside. When air, moisture, and chemicals seep into reinforced concrete, the bar rusts, expanding in diameter four or five-fold, which destroys the surrounding concrete. Usually 70-80 years.
Pros: economical when ingredients are readily available, long life, low maintenance requirements, unlikely to rot, corrode, or decay, molded or cast into any shape, non-combustible material, withstand high temperatures, resistant to wind, water, rodents, and insects, often used for storm shelters
Cons: low tensile strength, low ductility, low strength-to-weight ratio, susceptible to cracking
Decay: harsh weather, decay of connected materials (eg steel), physical destruction
GLASS
Primary ingredient: silica/quartz sand without iron impurities as the iron will cause the glass to appear greenish when present.
Other ingredients: sodium carbonate, calcium oxide, magnesium/aluminium oxides. Sodium carbonate lowers temperature necessary to make glass commercially. However, it permits water to pass through the glass, so calcium oxide, is added to counter this. Magnesium/aluminium oxides may be added to make glass more durable. These make approximately 30% of ingredients.
Chemicals: chemicals can be added to produce desired colours. Iron/copper oxide can be added to create a green effect. Sulfur compounds create yellow, orange, brown or black effect, depending on how much carbon or iron is included.
Mixture is melted into liquid. Commercial silica is melted in a gas-fired furnace. Without additives becomes glass at a temperature of 2300 degrees Celsius. Sodium carbonate lowers required temperature to 1500 degrees Celsius. Stir mixture to make it even and get rid of bubbles.
Molten glass is poured into a bath of molten tin for support and blasted with pressurized nitrogen to shape and polish it. This is how glass panes are made.
Annealing: heat treat glass to strengthen and remove stress points that formed during cooling. Then the glass is treated to improve strength and durability.
Glass lifespan: approximately 40 years
Decay: harsh weather, erosion, physical destruction
MARBLE
Large cubes of marbles are extracted from the ground.
Piece is loaded on platform supported by hydraulic lifts that lift marble into steel saw blades slicing from above.
Slab is placed face down and diamond-encrusted abrasive pads grind the surface to smooth the material. It is then sprayed with epoxy sealer and left for 48 hours. This is then repeated on the other side of the material.
Decay: chemical reactions (weather), physical destruction
CONCRETE
Concrete is a mixture of two components: aggregate and paste.
Aggregates: sand and
various sizes of gravel and crushed stone. Fine aggregate: 5mm or less. Course
aggregate: up to 40mm.Paste: limestone + clay + gypsum + various other chemicals and minerals = cement. These materials are crushed, mixed in appropriate proportions, burned and ground. Resulting mixture is combined with water where a chemical process called hydration takes place, and the resulting paste dries into a solid stone-like mass.

Exp2 Week 1: Reflection
Investigating into materials is interesting and will help with learning how things will break or decay over time. It makes me think much more about building materials as well as other synthetic things people own and how long they'll last after all the humans are gone. Are they going to be used as part of animals' homes or somehow become part of nature overtime if plants are exposed to radiation since the humans that store it are no longer there to maintain it?
Exp2 Week 1: House Research
House at Bordeaux
- concrete shell
- the middle living area is a glass room which takes up half the level is out in the open.The entire room is an elevator platform which rises and lowers to other levels of the house; changing plan when it stops on one of the floors. Single wall intersects each level, next to the elevator.
- continuous space
- the entire building on travertine plinth
- U-shape walls on both ends of building, also travertine, forms pools on both ends of house
- floor slabs project over the pool
- the roof plates are relatively small, supported by cruciform columns covered in chrome
- plates of high-grade stone materials like veneers of marble and golden onyx, tinted glass of grey, green, white, and transparent, act as spatial dividers
- structural system: steel frame

- the lower level which is cavern level below ground is sheltered from most light during the day
- the top level controls light through the 'portholes' carved into the concrete walls on each side. The large porthole at the end of the house can be opened.

Rudin House
