Description:

The artificial sand produced by proper machinescan be a better substitute to river sand. The sand should be sharp, clean andcourse. The grains should be of durable material. The grain sizes must be suchthat it should give minimum voids. The presence of clay and silt retards thesetting of the cement and makes the mortar weaker and the walls or the slableaks and holds dampness.

The sand in the mortar does not add any strengthbut it is used as an adulterant for economy and with the same it prevents theshrinkage and cracking of mortar in setting. The sand must be of proper gradation(it should have particles from 150 microns to 4.75 mm in proper proportion)When fine particles are in proper proportion, the sand will have less voids.The cement required will be less when there will be less void in sand. Suchsand will be more economical.

Manufactured  or  Artificial  Sand  V/s  Natural  or  River  sand 

The Civil engineers, Architects, Builders, andContractors agree that the river sand, which is available today, is deficientin many respect. It does content very high silt fine particles (as in case ofFilter sand).

Presence of other impurities such as coal, bones,shells, mica and silt etc makes it inferior for the use in cement concrete. Thedecay of these materials, due to weathering effect, shortens the life of theconcrete.

Now-a-days, the Government have put ban onlifting sand from River bed.

Transportation of sand damages the roads.

Removing sand from river bed impact theenvironment, as water table goes deeper & ultimately dry.

General  Requirements  of  Manufactured  Sand/Artificial  Sand

All the sand particles should have highercrushing strength.

The surface texture of the particles should besmooth.

The edges of the particles should be grounded.

The ratio of fines below 600 microns in sandshould not be less than 30%.

There should not be any organic impurities

Silt in sand should not be more than 2%, forcrushed sand.

In manufactured sand the permissible limit offines below 75 microns shall not exceed 15%.
