Parameters

CS Sand

River Sand

Process

Manufactured in factory.

Naturally available
on river banks.

Shape

Angular and has rougher
texture. Angular aggregates
demands more water. Water
demand can be compensated
with cement content.

Smoother texture with
better shape. Demands
less water.

Moisture Content

Moisture is available only
in water washed CS Sand.

Moisture is trapped in between
the particles which is good
for concrete purposes.

Concrete Strength

Higher concrete strength
compared to river sand used
for concreting.

Lesser concrete compared to CS Sand

Silt Content

Zero silt

Minimum permissible silt
content is 3%. Anything more
than 3% is harmful to the
concrete durability. We can
expect 5 - 20% slit content
in medium quality river sand.

Over Sized Materials

0%. Since it is artificially
manufactured.

1 - 6% of minimum over sized
materials can be expected.
Like pebble stones

Marine Products

0%

1 - 2% like sea shells, tree
barks etc

Eco Friendly

Though CS Sand uses natural
coarse aggregates to form,
it causes less damage to
environment as compared to
river sand.

Harmful to environment.
Eco imbalances, reduce ground
water level and rivers
water gets dried up.

Price

CS Sand price ranges from
Rs.35 - Rs.45 per cubic feet .

River sand price varies
depends on its availability.

Adulteration

Probability of adulteration
is less.

High probability of adulteration
since filtered sand (a type
of pre-washed sand which contains
high silt contents) are
mixed together. As a rule,
supply shortage always
brings adulterer products
to the market.

Applications

Highly recommended for
RCC purposes, plastering
and brick/ block works.

Recommended for RCC,
plastering and brick/ block work.

Quality

Better quality control
since manufactured in a
controlled environment.

No control over quality since it
is naturally occurring. Same
river bed sand can have
differences in silt contents.

Particle passing 75 micron

Up to 15% (IS: 383 - 1970)

Varies depending on source.
