Environmental impact of sustainable green concrete

TLDR: In this paper, the importance of manufacturing green concrete using recycled waste materials and nanoparticles with its advantage and scope is discussed in detail, where the authors also discuss the potential of green concrete mix for commercialization by providing developers and contractors with an alternative concrete.

Abstract: The manufacture of cement contributes to about 8%–10% of CO2 emission and globally increases the temperature of the environment. The development of sustainable green concrete by recycling the waste materials minimizes the usage of natural resources used for cement and concrete production and reduces its adverse effect on the environment. There are numerous waste materials from different industries and agriculture which are disposed as landfills, without the knowledge of recycling the materials. To reduce the consumption of raw materials during cement production and other natural resources used during the concrete casting, these waste materials should be replaced in the concrete mix. The selection of materials for concrete mix would be based on the materials performance and cost. The new research trend showed the importance of nanotechnology by replacing existing materials with nanoparticles or nanomaterials. This will lead to the development of eco-friendly Green Concrete as a stronger and more durable concrete. This green concrete mix will have potential for commercialization, by providing developers and contractors with an alternative concrete. In this chapter, the importance of manufacturing Green Concrete using recycled waste materials and nanoparticles with its advantage and scope will be discussed in detail.
