21-11-2017· River sand has a silica content. Excessive presence of silica content makes the sand useless for concrete work and responsible for efflorescence on the surface in future. To overcome this, the sand should be tested for silica content before using it. A good sand should have less than 5% of silica in it. M-Sand (Manufactured Sand) :-

To a geologist or mineralogist, "silica" only means a SiO2 compound, regardless of its actual crystal structure. If you had pure SiO2 glass, you could describe it as being made of silica, and you can say that chemically, pure quartz is also SiO2. ...
Before we get into the advantages and disadvantages of manufactured sand, what exactly is manufactured sand? Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sand-sized particles. Natural sand, on the other hand is the naturally formed sand extracted from river beds.
To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and "autoclaved" at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules.. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday items such as glass, construction materials, personal ...

Silica sands, These type of sands are normally manufactured using a crushing and washing process until the desired grain sizes are reached, This type of sand is normally manufactured from quartz deposits that are high in silica content, the grains can be sub-angular to angular in shape and lock together better providing a more stable riding surface for all disciplines.
Washed sand comes in coarse, medium, fine and ultra fine granule sizes, of which each size classification requires sand granules that are within a specific diameter range. Whatever the size, washed sand isn't necessarily silica sand, and silica sand isn't necessarily washed.
Considering, the acute shortage of river sand, huge short coming on quality of river sand, high cost, greater impact on road damages and environmental effects, The Construction Industry shall start using the manufactured sand to full extent as alternative, reduce the impacts on environment by not using the river sand.
