12 - Quarry dust

Abstract

The production of aggregate for use in concrete production yielded a significant amount of fines fraction during the crushing operation at the quarry. The fines fraction, also widely known as quarry dust (QD), poses environmental risks such as land and air pollution in the absence of a proper disposal channel. In recent years, numerous reported studies explored the feasibility of using QD as constituent aggregates in concrete production as a channel for extensive reuse and recycling of the material. However, the works were carried out as separate experimental investigations by various researchers. Hence, the present work aimed to consolidate the body of knowledge reported on the method to use QD as constituent material in concrete and its influence on the properties of concrete. Therefore, a comprehensive review of the physical and chemical properties of QD is presented. Besides, the effect of the inclusion of QD as constituent material on the workability and mechanical properties is deliberated based on current development. The present work also establishes a consolidated understanding of the durability properties and length change behaviour of concrete containing QD. In conclusion, the QD is a feasible fine aggregate and filler material for replacing fine natural aggregate in concrete production. Moreover, a suitable proportion of the QD material could achieve the desired properties of concrete.
