SUMMARY:

Population growth and urbanization in recent decades have favored the construction industry in Brazil and worldwide: more buildings were built; more reforms were implemented; more demolitions were carried out. As a result, there was an increase in the generation of waste, which results in negative impacts for society and the environment if these materials are improperly disposed of. Worldwide, around 25 billion tons of concrete are produced annually, with developing countries such as China and India being the largest consumers (WANG et al., 2020). However, according to Nedeljkovic et. al. (2021), the exposure of this material to the environment, combined with the lack of maintenance, causes an intense process of degradation of concrete structures, thus, they end up being demolished or renovated, generating a large amount of solid waste.

According to Zhang et. al. (2021), the main form of disposal for construction and demolition waste (RCD), continues to be stacking in landfills, occupying large areas and polluting the environment. This waste is estimated at more than 4 million that are sent to these landfills, composed of difficult-to-handle materials such as steel, concrete, glass, ceramics, natural rocks, asbestos and mercury. With this, there is a great challenge for countries to reduce these wastes, introducing different legislations and seeking to raise awareness through different methods, such as the waste management strategy, including minimization, reuse and recycling (AKHTAR AND SARMAH, 2018) . Thus, a viable alternative for the reduction of CDW is the reprocessing of this material as aggregates in the production of new concrete. Although there is a variety of construction waste, what has the greatest potential for use, and will be used in this work, will be concrete waste.
