    Manufactured sands are produced by crushing rock deposits to produce a fine aggregate which is generally more angular and has a rougher surface texture than naturally weathered sand particles. Manufactured sands can also contain significant quantities of rock dust. As natural sand deposits become depleted near some areas of metropolitan growth, the use of manufactured sands as a replacement fine aggregate in concrete is receiving attention.

    Designers, specifiers, contractors, and material suppliers need to understand the effects of manufactured sand particle shape characteristics and angularity as well as fines content on concrete water demand and concrete durability, including the effects of interrelationships between manufactured sand characteristics.

    As part of a comprehensive research program, manufactured sand properties and their effects on fresh concrete properties, mechanical properties and concrete durability were investigated.

    Concrete containing commercially available manufactured sands with a wide range of particle angularities and fines contents were included in the laboratory testing program on deicer salt scaling. Angularity of particles and quantity of fines were found to contribute to salt scaling.
