What Is M Sand? – Made of, Properties & Applications

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.



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


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.




·  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.

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.



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.
