DIFFERENCE BETWEEN M SAND AND RIVER SAND

DIFFERENCE BETWEEN M SAND AND RIVER SAND

Concrete with m sand has very poor permeability compared to river sand. But when river sand is used in concrete, the penetration of concrete is less compared to river sand. It has high water absorption of 2 to 4%. While the water absorption of sand from rivers is less than 1.5 to 3%. In the following table column, we will discuss the difference between m sand and river sand

 

M Sand (Manufactured Sand)	River Sand
Made of on factories under supervision	Available naturally at river beds.
Moisture is only available in water-washed M sand.	Moisture is trapped between the fine particles for concrete purposes
High concrete strength compared to river sand	Low concrete strength compared to M sand
The sand particles of M sand are in cubic form. This makes the bond stronger.	Bonding is weak because of its Excessive presence of flaky, sharp and angular grains
zero slit content	3-20% silt content
0% of marine products	2-4% Marine Products (shells, etc)
No oversized products as they are well standardized and manufactured under control.	6-10% enlarged material (stones) should be sieved
Better quality control from being manufactured in a controlled environment	There is no restriction on quality as it occurs naturally. There may be differences in silt contents in the same river bed sand.
An eco-friendly product, which causes less damage to the environment compared to river sand.	Harmful to the environment. Environmental imbalances reduce groundwater levels and river water dries up.
M-sand dry density of 1750 kg/m3	Naturally Sand dry the density of 1600 kg/m3
M-sand specific gravity is approximate 2.73 (Depend on parent rock.)	River sand specific gravity is approximate 2.65 (Depend on rocks in the catchment area.)
Made of on factories under supervision	Available naturally at river beds.
Moisture is only available in water-washed M sand.	Moisture is trapped between the fine particles for concrete purposes
High concrete strength compared to river sand	Low concrete strength compared to M sand
The sand particles of M sand are in cubic form. This makes the bond stronger.	Bonding is weak because of its Excessive presence of flaky, sharp and angular grains
zero slit content	3-20% silt content
0% of marine products	2-4% Marine Products (shells, etc)
