Concrete is characterized by the type of aggregate or cement used, by the specific qualities it manifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete.

Off-specification concrete which does not achieve this minimum strength value may be evaluated for consideration as a cured concrete by the solid waste permitting agency on a case-by-case basis. Cured concrete may also contain embedded steel, wood, or plastic materials used in the reinforcement or tensioning of concrete structural elements.
Demolition debris is the kind of waste generated when a building is demolished. As defined in state law, it includes: concrete, brick, bituminous concrete, untreated wood, masonry, glass, trees, rock and plastic building parts. It does not include garbage (called " waste" or "municipal solid waste") that you generate at
The waste generated in the building and construction sector is termed construction and demolition waste (CDW) or construction and demolition debris (CDD). CDW is a general term that can be defined as the waste material produced in the process of construction, maintenance, renovation, or demolition of buildings, representing a big proportion of the overall waste …

This waste, comprising old concrete slabs, pipes, bricks, blocks, and other forms of concrete rubble, is transported to recycling facilities. Facilities like Moreton Bay Recycling have set up designated areas where tradespeople, demolishers, and construction companies can conveniently drop off their concrete waste. The ease of this process is ...
Recycled concrete fines and recycled concrete paste . New uses for concrete demolition waste are in development. Recycled concrete fines are the residue of concrete waste after recycled aggregates are removed. It consists of cements pastes and sand. It accounts for ~15% of recycled concrete and currently has only low value uses.

Loosely speaking, waste that comes from a factory might be "industrial waste," as explained above (see Q.1). But if waste is a "listed" material or P-listed waste, which the EPA defines as " pure and commercial grade formulations of certain unused chemicals that are being disposed, " then it's "hazardous waste."

Wood can be chipped and used as mulch or biomass fuel. Metals can be separated and sent to recycling facilities. Recycling not only reduces the amount of waste sent to landfills but also conserves ...
Overall, from a holistic point of view, the meaning of sustainable concrete based on waste management hierarchy (3R strategy) is aiming at a "high-quality concrete". In this case, waste generation and raw materials consumption are reduced, which in turn alleviates the environmental impacts observed throughout the life cycle.
Special waste is defined by KRS 224.50-760 as being a waste "of high volume and low hazard" designated to be special waste by the Energy and Environment Cabinet.
