Quarry limestone dust as fine aggregate for concrete

Abstract

In quarrying activities, rock is extracted and transformed into aggregate of various sizes for civil engineering applications. In this process waste, fine aggregates is generated. The disposal of this type of waste is a further cost in the extraction process, but also a possible cause of environmental degradation and pollution (e.g. leaching into water reserves, atmospheric pollution as a result of small particles causing respiratory diseases or deposited on plants disrupting photosynthesis, affecting aquatic habitats, etc.).
