TREND TO MORE USE OF STONE SAND

Specifications for the fine aggregate fraction of concrete have been developed almost exclusively on the basis of experience with natural sand since, for many years, this was virtually the only type used. As available sources of natural aggregates have become more distant from the market areas, their cost has increased and, in some areas, the natural sands have been replaced by manufactured sand produced by the crushing and classification of stone. Unfortunately, during the years that stone sand has been used, very little recognition has been made of its special characteristics. To meet the established fine aggregate specifications, fine mineral particles have been washed out. This paper discusses the properties of stone sand and how these characteristics could be used to their best advantage. Properties discussed include gradation, particle shape and texture. Also discussed is the influence these properties have on concrete properties and performance.
