Mining Sand As Fine Aggregate Concrete

natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures.

Research on River Sand Substitutes for Concrete Production ...

Jun 01, 2016· The strength of the concrete is related to the composition of sands used in concrete mix. Hence, the content and type of clay, and the percentage of feldspar and mica in the aggregates should always be determined before they are used in the concrete mix. The presence of clay in the natural sand reduces the concrete strength by nearly 10 MPa.
