Said Kenai, in Waste and Supplementary Cementitious Materials in Concrete, 2018. Abstract. Construction industry generates huge amounts of debris that needs to be recycled and reused as recycled aggregates (RAs) for partial or total substitution of natural aggregates. Recycling reduces waste and reduces energy consumption and hence contributes to a more sustainable construction industry.
