of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate.

Use of crushed granite fines or crushed rock fines as an alternative to sand in concrete production was also reported [7]. In Makurdi, the capital of Benue state of Nigeria, in West Africa, the sole source of fine aggregate for concrete production is sand obtained from the bed of River Benue.

The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.

Hence, partial or full replacement of fine aggregates by the other compatible materials like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust, and others are ...

Previous work (Janssen, et al., 2006) demonstrated that the use of recycled concrete fines could offset some or all of the delayed strength‐gain effects from cement‐GGBFS blends. Current work appears to indicate that the use of such fines could allow for increased cement replacement with no additional reduction in early strength gain.

1999). The ASTM C-33 specification for fine aggregate allows up to 10% of the material finer than a #100 mesh sieve. Weaver et al. (1998) recommends that sand used for constructing sand filters has no more than 4% fines passing the 100 sieve size. Ball (1997) indicates that sand with excessive fine

Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher dusts or small crushed sand samples on concrete properties [8,12,13]. However, little work has been performed on the complete replacement of natural fine …

Research on natural crushed rock sand, copper slag, waste foundry sand, coal ash, recycle sand etc. has shown that these can also be used in concrete as fine aggregate [7, 8], either in full or as fractional replacement of natural sand [8-10].
