3. INTRODUCTION
Sand Mining is a coastal activity referring to the
process of the actual removal of sand from the
foreshore including rivers, streams and lakes.
Sand is mined from beaches and inland dunes and
dredged from ocean beds and river beds.
4. DRAWBACKS OF SAND MINING
Collapse of river bank.
Loss of adjacent land or structure
Alteration River bed
Risk to aquatic habitat
Force the river to change course
Lead to flooding
Reduced light penetration
Increase erosion
Increase Turbidity
Loss of agriculture land
6. Introduction of M-sand
M sand is a form of artificial sand, manufactured
by crushing large hard stones, mainly rocks or
granite, into fine particles, which is then washed
and finely graded. It is widely used as a substitute
for river sand for construction purposes, mostly in
the production of concrete and mortar mix.
7. Advantages of using M-sand &
Marketing Strategy
Reduce transportation cost
Less processing cost
Easily available
Decrease transportation time
Greater Durability
Eco-friendly
High strength of concrete
Better workability of concrete
8. Supply Chain Management Strategy
1. Place buffers along the supply chain
2. Diversify your manufacturing and sourcing network
3. Invest in demand forecasting
4. Standardize your processes
9. Conclusion
The large-scale mining of rivers and below the existing streambed level has adverse
impacts on the existing environment.
It is therefore concluded that the mining of sand should be subjected to a strict
regulatory regime and should be carried out based on the approved framework of
the mining plan. Also, it should provide rehabilitation and reclamation of the mined-
out zones in the future.
So far, the inherent deficiencies of natural river sand are extensively used for the
modification of concrete properties by incorporating manufactured sand as a partial
replacement for river sand.
It can also be concluded that the M-sand can be utilized as an efficient fine aggregate
in concrete in order to meet the global scarcity of river sand in the future.
The use of M-sand eliminates the global scarcity of river sand, and it prevents
associated environmental problems such as indiscriminate sand mining and soil
erosion, thereby enhancing and contributing to environmental sustainability.
