ROBO SAND


2/24

Robo sand is a artificial sand, that is now increasingly

bein referred b leadin builders, develo ers across the

country, having proved its mettle and superiority over

river sand.


3/24

Vital to construction, both for concrete and masonry

work, and needed in large quantities, sand has been

traditionally lifted from dredging of creeks and

riverbeds which in recent times has been causing

environmental worries over possible groundwater

depletion.


4/24

To reduce dependence on river sand for construction

purposes, the new mechanised sand made from

granitegranitegranitegranitehas been positioned as an ideal substitute in

all aspects. Those promoting the Robo Sand describe

it as a quality material offering same strength forstructures and better than the conventional sand in

some features.


5/24

Robo Sand protects environments, promotes ethical

and legal construction and also eliminates all the

disadvantages of river sand. Apart from this, using

results in substantial saving of cement and thus

slashing the construction costs.

DESCRIPTIONDESCRIPTIONDESCRIPTIONDESCRIPTION

It is perfect substitute for river sand. The product

is manufactured as per IS 383 -11970

spec cat ons an con rms to zone- stan ar s.The gradation, cubical shape of the particle helps

in producing good concrete of high compressive

strength and greater durability in construction.

PROCESS

The plant consists of three circuits namely

Primary circuit, Secondary circuit and Tertiary

circuit wherein a three-stage crushing takes place.


8/24

A 500 mm down size granite rock that is brought

from the quarry via operations which involve drilling,blasting, segregation, secondary breaking and

,

Circuit consisting of one Jaw Crusher that sizes down

this granite rock to produce 150mm down size

aggregate.


9/24

This 150 mm down size rock is fed into the

Secondary Circuit consisting of one Cone Crusher to

produce a 40 mm down size aggregate which in turn

is fed into the Tertiary Circuit consisting one Vertical

Shaft Impactor that produces Sand and Aggregate of

the required Gradation & Shape.


10/24

Thus the process is quite similar to Mother

Natures long drawn out process of creating sand,but here characterised by acceleration that

telescopes formation time into minutes.

High Compressive Strength

Since the particles of RoboSand are uniformly cubical

in shape and have different internal gradation, they

RoboSand is in fact GREEN SAND it is an eco-

friendly product, in the sense, it shows an alternative

to the ill- effects (gground water depletion, water

scarcity, fall in farm production,Threatening the very

safety of the Bridges, Dams etc.)of dredging,mining

and indiscriminate quarrying of river beds which isposing a great threat to the environment.


17/24

Defects RoboSand has optimum initial and final

setting time as well as excellent fineness which will

help to overcome the deficiencies of concrete such as

segregation, bleeding, honeycombing, voids and

capillary.

Unmatched Economy RoboSand offers great savings

and helps in slashing overall project cost.


18/24

RoboSand, unlike river sand, contains no impurities

which means there is absolutely no wastage and

you get exactly the quantity you paid for.

physical properties, ensures significant reduction in

the cement used in the concrete &masonry works,thus saving substantially on cement costs.

Application: Filling/Levelling

Description:

It is widely used for levelling and filling horizontal surfaces.The

characteristics of the product ensures that the compaction levels remain

same and does not sink at a later stage due to movement of loads or

additional weights.The strength of the substrate remains in stablecondition when spread in even layers both for internal and external

applications.
