Review report on dry and wet classification of filler materials for concrete : State-of-the-art : FA 2.3 High quality manufactured sand for concrete : SP 2.3.1 Filler technology

Abstract

Due to depletion of natural sand resources in many central locations, it is an increased production and utilisation of crushed sand for concrete purposes. This crushed and processed sand is referred to as; Manufactured sand. Due to high and often variable content of fines (i.e. material less than 125 μm), in crushed sand, it is a necessity to be able to reduce and enable control of the amount of fines. This could be done either by wet- or dry processing of the sand. This report reviews some of the most common processes for both wet- and dry classification applied for manufactured sand. Some cases of experience in use are reported. Eventually in the report, a set of factors are discussed when selecting the most appropriate system and equipment for classifying manufactured sand. It is the anticipation that this report will assist aggregate producers in selecting appropriate equipment in order to produce high quality manufactured sand at a reasonable cost.
