Sand is an unavoidable material in construction, it is used in every process such as
·
Concrete
·
Plastering
·
PCC
·
RCC
·
Backfilling
·
Earth Embankment And
In Many Other Process.
River
sand naturally lays on the riverbank, which decomposes from the rock for
decades and lays on the riverbank.
However,
due to the rapidly growing urbanization, the use of river sand has increased
rapidly in the last decade, but at the same time, most of the river sand is not
available for supply.
Excessive
excavation of sand leads to drying out of groundwater in certain areas and
around it, which can be very harmful to the environment.
Due
to the unavailability of river sand and environmental impact, the use of M sand
in the construction industry began to increase day by day. The use of M sand in
construction is really appreciated because it is eco-friendly.

read: DIFFERENCE
BETWEEN M SAND AND RIVER SAND
What is Manufactured Sand?
After crushing and washing
the quarry stones to the required grain sizes, M sand is prepared by grading
the crushed cubic shape with rounded edges, which became building material.
It is called M-sand.
M SAND IS MADE OF? (SOURCE)
As you know the aggregates are
produced from igneous rocks, sedimentary rocks and metamorphic rocks. which we
discussed in the ALL
YOU WANT TO KNOW ABOUT COARSE AGGREGATE (GRAVEL) topic.
Hard rocks obtained from
the above process will be involved in the following process.
MANUFACTURING PROCESS OF M SAND
· The hard rocks are
transformed into medium-sized stones by blasting it and those stones are
transported to the plant.
· The stones are then
washed and cleaned of dust and other contaminants (impurities).
· The cleaned stones
are placed into the primary crusher to crush the rocks into 40mm aggregates.
· After that, the 40mm
aggregates are sent to the secondary crusher, which forms 40mm aggregates to 20mm
or less.
· The aggregates are now
examined, and if you look at the oversized groups again, those groups are
involved in crushing.
· After the 1st stage
screening, the aggregates are sent to the impact of the vertical axis to be
crushed into cubic shape, which is further reduced below 4.75mm.
· If enlarged particles are found after secondary screening, it is sent back through VSI.
· Finally, the sand
was washed and more than 150 microns of particles were automatically removed
from the screening process and ready for use in construction.
PROPERTIES OF M SAND
Eco-friendly - As it is made artificially from rock particles it is
less harmful to the environment as compared to river sand.
Material Quality – In its manufacturing process The quality of the sand
can be controlled so, the quality of the particles are well balanced
Shape
- M Sand with a cube shape and grounded edges.
Workability - Due to its rough texture and shape, it affects the
workability of concrete.
Strength - The strength of concrete in M Sand is very high
compared to river sand used in concrete. Because it is made of boulders, it has
good compressive strength.
Quality of Concrete - We often experience concrete bleeding and segregation
that can lead to concrete cracking when pouring concrete and compaction. Also,
honeycomb formation occurs after the concrete hardens. Those quality issues do
not occur when M sand is used in concrete.
Impurities - M sand does not contain silt particles or other
marine impurities such as mica and silica, which can affect the quality of
concrete.
PEOPLE ALSO ASK
Is M sand suitable for construction?
Yes.
There is no difference from river sand compared to M sand quality and strength.
And evidence. The only difference is that it is made artificially.
Can we use M Sand for RCC?
Yes,
M-Sand (crushed sand) can convert 100% river sand into a concrete mix ratio. On
the other hand, river sand may contain organic contaminants and silt. The
availability of river sand throughout the year is not uniform, but you can
continue to supply M-sand.
The
M sand is perfect for construction, and it is classified into three types based
on its construction activity.
Is M Sand good for plastering?
Yes,
M-Sand is used for concrete, brick, block & masonry work purposes.
Plastering M-Sand is used for Wall plastering and brickwork purposes.
What is M Sand and P sand?
P
sand stands for Plastering sand. It is Other type of manufactured sand (m sand)
(it is smooth)
Advantages and Disadvantages Of M-SAND
Advantages of M-SAND
·
Eco Friendly
·
Strength Is High
·
No Presence Of Sea
Particles And Slit
·
No Over-Enlarged
Particles.
·
It Has Good Control Of
Quality.
·
It Is Available In
Three Types, Which Can Be Used For All Construction Work.
·
It is cheaper than
river sand
Disadvantages of M Sand
·
Low workability due
to its shape and rough texture.
·
No moisture if not
washed in water.
·
Crushed sand can be
coarse and angular structure. This will lead to higher water and cement demand
to achieve the expected work efficiency.
