Selected manufactured sands can be used as part of the fine aggregates to deliver workable concrete for general applications and to provide good skid and abrasion resistance to concrete pavement. In concrete pavement, it was found that the use of free silica limit in the selection of natural sand to provide good skid resistance to concrete pavement does not necessarily apply to manufactured sands.
manufactured sand (M-sand) instead of natural river sand in making concrete. M-sand is obtained by crushing the natural granite stone in the vertical shaft Impact crushers and screening the output form the fine aggregates of size less than 4.75mm. Some studies has been reported the effect of M-sand on strength and durability properties of

Dec 19, 2019· Manufactured Sand in Concrete Posted on December 19, 2019 May 18, 2020 by stonasand The reduced availability of natural sands, particularly along the east coast of India, and the need to better utilise sand-size material generated in the aggregate crushing process, has combined to encourage the development of ‘Manufactured Sand’.
More and more, GCP Applied Technologies' scientists and technical experts have observed the use of manufactured sand over natural sand, as a fine aggregate in ready-mixed concrete. THE PRIMARY REASON: Environmental concerns have made what remains of available natural sand resources an economically unviable option for the concrete producer.
In concrete pavement, it was found that the use of free silica limit in the selection of natural sand to provide good skid resistance to concrete pavement does not necessarily apply to manufactured sands.
