As a comparison, plastic road claims to dispose 8–10 kg (or 4-6%) of selected and washed plastic waste in the road surface per tons of asphalt, [4] while waste light concrete can dispose around 800 kg / tons of road base concrete with only low energy consumption shredding and mixing at room temperature. However, these two technologies can be ...
One being Green concrete that is produced by recycled waste materials from various industries , another being Ashcrete, a material made from a mix of lime and water that acts similar to cement. Black furnace slag is also a strong alternative made from molten iron slag into water, along with Micro Silica, Papercrete, composite cement, and post ...
Soda lime glass from virgin raw materials theoretically requires approximately 2.671 GJ/tonne compared to 1.886 GJ/tonne to melt 100% glass cullet. [6] As a general rule, every 10% increase in cullet usage results in an energy savings of 2–3% in the melting process, with a theoretical maximum potential of 30% energy saving. [ 6 ]
Concrete waste that is rich in alkaline calcium compounds can be used to remove and recover various elements from an aqueous solution. Waste concrete has been used as a sorbent to remove phosphorus from wastewater after the removal of excess sludge in sewage treatment plants. [27] Concrete waste may also be used as an inexpensive gas treatment ...
Ground plastic may be used as a construction aggregate or filler material in certain applications. [142] [143] While generally unsuitable in structural concrete, plastic's inclusion in asphalt concrete, (forming rubberised asphalt), subbase and recycled insulation can be beneficial. [144] An example of this is the construction of plastic roads ...
Portland cement has been used to treat more contaminated material than any other S/S binding agent because of its ability to bind free liquids, reduce permeability, encapsulate hazardous materials, and reduce the toxicity of certain contaminants. Lime can be used to adjust the pH of the substance of drive off water by using high heats of hydration.
Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size. [1] Leaching can occur naturally seen from plant substances (inorganic and organic), [ 2 ] [ 3 ] solute leaching in soil, [ 4 ] and in the decomposition of organic materials. [ 5 ]
Cement powder in a bag, ready to be mixed with aggregates and water. [1] Cement block construction examples from the Multiplex Manufacturing Company of Toledo, Ohio, in 1905. A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together.
