===Material===
Material infrastructure is defined as "those immobile, non-circulating capital goods that essentially contribute to the production of infrastructure goods and services needed to satisfy basic physical and social requirements of [[economic agent]]s".<ref name="Torrisi" /> There are two distinct qualities of material infrastructures: 1) fulfillment of [[social needs]] and 2) [[mass production]]. The first characteristic deals with the basic needs of human life. The second characteristic is the non-availability of infrastructure goods and services.<ref name="Torrisi" /> Today, there are various materials that can be used to build infrastructure. The most prevalent ones are asphalt, concrete, steel, masonry, wood, polymers and composites.<ref>{{Cite web|title=Infrastructure Materials Engineering – Department of Civil, Architectural and Environmental Engineering|url=https://www.caee.utexas.edu/research/specialities/infrastructure|access-date=2020-11-05|website=caee.utexas.edu}}</ref>
