Cast iron is a class of iron–carbon alloys with a carbon content more than 2%.

Its usefulness derives from its relatively low melting temperature.

The alloy constituents affect its color when fractured; white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing.

Pavement lights (UK), vault lights (US), floor lights, or sidewalk prisms are flat-topped walk-on skylights, usually set into pavement (sidewalks) or floors to let sunlight into the space below.

They often use anidolic lighting prisms to throw the light sideways under the building.

They were developed in the 19th century, but declined in popularity with the advent of cheap electric lighting in the early 20th.

Older cities and smaller centers around the world have, or once had, pavement lights.

In the early 21st century, such lights are approximately a century old, although lights are being installed in some new construction.

Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix.

This itself may have been made using a pattern or model of the final object.

Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures over time.

Concrete is the second-most-used substance in the world after water, and is the most widely used building material.

Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined.

In situ (often not italicized in English) is a Latin phrase that translates literally to "on site" or "in position." It can mean "locally", "on site", "on the premises", or "in place" to describe where an event takes place and is used in many different contexts.

For example, in fields such as physics, geology, chemistry, or biology, in situ may describe the way a measurement is taken, that is, in the same place the phenomenon is occurring without isolating it from other systems or altering the original conditions of the test.

The opposite of in situ is ex situ.
