Crushing concrete from an airfield. Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. [1] Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.
Adaptive reuse is defined as the aesthetic process that adapts buildings for new uses while retaining their historic features. Using an adaptive reuse model can prolong a building's life, from cradle-to-grave, by retaining all or most of the building system, including the structure, the shell and even the interior materials.

Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding. Conversely, concrete is one of the most powerful tools for proper flood control, by means of damming, diversion, and deflection of flood waters, mud flows, and the like.
Demolition waste. Demolition waste is waste debris from destruction of buildings, roads, bridges, or other structures. [1] Debris varies in composition, but the major components, by weight, in the US include concrete, wood products, asphalt shingles, brick and clay tile, steel, and drywall. [2] There is the potential to recycle many elements of ...
Of total construction and demolition (C&D) waste in the United States, 90% comes from the demolition of structures, while waste generated during construction accounts for less than 10%. [ 2 ] Construction waste frequently includes materials that are hazardous if disposed of in landfills. Such items include fluorescent lights, batteries, and ...
Deconstruction of a building. In the context of physical construction, deconstruction is the selective dismantlement of building components, specifically for reuse, repurposing, recycling, and waste management. It differs from demolition where a site is cleared of its building by the most expedient means.
Prestressed beam without load. Prestressed beam with load. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] It was patented by Eugène Freyssinet in 1928.
A floor-by-floor demolition of the McGuire Apartments building, as opposed to the implosion method used for Seattle's Kingdome in 2000, [8] was approved by the City of Seattle in March 2011. [9] Contractor Lease Crutcher Lewis began salvage and demolition work on April 4, 2011, [10] [11] with the garage leveled beginning the following month. [7]
