Sand/ Artificial sand/ V.S.I is manufactured by granulating good quality
stone metal. The partical size and shape and also the overall
gradation of crushed sand is controlled in
the manufacturing process, which takes place in a fully automated
state of the art V.S.I (Vertical Shaft Impactor) unit. The result is excellent
quality sand with consistent gradation. Thus, the major drawbacks
of natural sand like irregular particle sizes, presence of organic
impurities etc. are totally overcome. Crushed sand is widely
used around the world and technicians of major projects around
the world insist on the complusory use of crushed sand because
of its consistent gradation and zero impurity. The use of crushed
sand results in dense and cohesive concrete thus increasing
the strength and life of the concrete. |

| Comparison between the River Sand and
Crushed Sand |
| |
| River
Sand |
 |
Contains harmful impurities like mud,
soil, silt, salt, alkalis, coal, mica, shoal, sea shell,
bone, organic matter etc. |
|
No consistency in particle sizing due
to different sources, hence accuracy of mix design becomes
doubtful. |
|
Irregular sizing results in wastage
in the form of singles to the tune of 10 -15% |
|
Erratic supply & fluctuating prices
make it difffcult to control project cost. |
|
Extraction of sand from River beds
is an enviromental hazard. |

| Nirman's
Crushed Sand |
|
Contains no organic Impurities, hence
it gives increased strength of Concrete with same cement
content. |
|
Gradation of sand is controlled in
the manufacturing process, hence mix design can be accurately
used due to consistent gradation. |
|
No wastage since Sand is already sieved
in the required size ( below
4.75 mm ). |
|
Consistency in supply as well as stability
in prices help in controlling the project cost. |
|
Does not harm the enviroment in any
way
|
|
| |
Nirman's crushed
sand a ready to use product for all constructional
activities without any processing on the site, as a better substitute
to natural sand.
