Crazybump Before and After:

Concrete:
Concrete is the product of mixing, aggregate (rock, sand, or gravel), cement and water. The setting of concrete is a chemical reaction between the cement and the water, not a drying process. This reaction is called hydration, it evolves heat as does any chemical reaction, and the process is irreversible.



Steel:
Steel is an alloy of iron with about 1 percent carbon. It may also contain other elements, such as manganese. Whereas pure iron is a relatively soft metal that rusts easily, steel can be hard, tough, and corrosion-resistant. Used to make almost everything from skyscraper girders, automobiles, and appliances to thumb tacks and paper clips, steel is one of the world's most vital materials



Brick:
brick. Solid, hollow, or indented building element, usually rectangular, but also other shapes for special purposes, manufactured from clay, concrete, sand, and lime, or other materials, formed in a mould, then burnt, set, or cured
