SPECULAR AND BUMP MAPS

RESEARCH ON 3X MATERIALS

CONCRETE
process of making the material: composed primarily of aggregate (coarse gravel, limestone, granite, sand), cement and water
how long will it last: depends on the environment, but usually a very long service life
what makes them corrode: steel?
structural pros: can be recycled, fire resistance
structural cons: weak in tension, larger earthquakes can generate very large shear loads, can fail during severe earthquakes
what they are typically used for: architectural structures, foundations, brick/block walls, pavements, bridges, roads, parking structures, footings...
environmental impacts: big contribution to greenhouse gas emissions


STEEL
process of making the material: is an alloy made by combining iron and other elements such as carbon
how long will it last: long life service
what makes them corrode: water condensing from air or rain
structural pros: hardness, ductility, tensile strength
structural cons: less ductile than iron
what they are typically used for: major components in buildings, infrastructure, tools, ships, automobiles, machines, appliances
environmental impacts: 100% recyclable



GLASS
process of making the material: metallic alloys, ionic, melts, polymers
how long will it last: long life service
what makes them corrode: overheated water, chemicals
structural pros: brittle and transparent
what they are typically used for: windows, mirrors
environmental impacts: can be recycled unless broken, if shattered- may injure those/ objects around them
