  • Potential use of Plastic Waste as Construction Materials

    Recycling of plastic waste as valued added product such as concrete appears as one of promising solution for alternative use of plastic waste. This paper summarized recent progress on the development of concrete mixture which incorporates plastic wastes as partial aggregate replacement during concrete manufacturing.Recycled Aggregates,Recycling of concrete is a relatively simple process. It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality. See ACI 555 (2001) for more information on processing old concrete into recycled concrete aggregates.

  • Waste Materials Used in Concrete Manufacturing ScienceDirect

    The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production. These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete.Waste & Recycled Material In Concrete Technology 1000,Waste & Recycled Material In Concrete Technology: Recycled-aggregate concrete containing fly ash is an example of construction material in harmony with this concept, whereby sustainable construction development is useful with satisfactory performance, in both safety and service of structures, at lower costs and with advantages over ordinary concrete.
