What Is M Sand?

M Sand means Manufactured Sand. It is manufactured from a cubical-shaped granite stone with grounded edges, washed and graded with consistency to be used as a substitute for river sand.

M Sand Meaning:

M Sand Mining is A fine aggregate that is produced by crushing stone, gravel, or slag.

M — Sand

Sand is an important ingredient in making concrete and mortar. The majority of counties in the world now promote the use of M-Sand (Manufactured Sand).

manufactured sand means sand that is produced by crushing quarry and rocks stones to desired sizes.

Why M Sand?

We know that the river sand is mostly used for construction purposes all around the world, majorly for concrete making, cement mortar, and concrete blocks.

Various factors show the need for manufacturing sand

1. Global scarcity of Natural Sand

Excessive sand exploration and limited consumption of natural aggregate sources have led to the implementation of new environmental/land use legislation. This law makes the supply of natural sand difficult and expensive. Nowadays sand mining is heavily taxed/ banned in many parts of the world.

2. Growing Demand for Fine Aggregates In Construction

it is nearly 30–35% volume of concrete is made up of fine aggregate. The UK construction industry demands approximately 200 Million Tonnes of aggregates every year for various construction purposes.

3. The Remote Location of Sandpits

Due to legislative restrictions on sand mining, the source of sand supply is now limited. Also, there are available in remote locations away from the area of consumption Leeds to the high cost of transportation.

4. Presence of Silt and Clay In Natural Sand

Natural sand contains a high amount of impurities like silt and clay which can damage screed and concrete if the sand is not given proper treatment to bring down clay and other impurity content to acceptable levels.

Some of the Alternatives to River Sand

- Manufactured Sand

- Fly Ash/ Bottom Ash/Pond Ash

- Copper Slag — Filtered Sand

- Sea Sand, Slag Sand

- Crushed Waste Glass

- Recycled Aggregate/C&D Waste Aggregate etc.

The demand for alternative materials of river sand for making concrete is increasing day by day as river sand cannot meet the rising demand of the construction sector.

It is fact that the river sand takes millions of years to form. Because of limited sources of natural sand, the cost of River sand has skyrocketed and its consistent supply cannot be guaranteed. Under this condition the use of manufactured sand becomes inevitable.

Issues and General Requirements of M Sand

The Civil engineers, Architects, Builders, and Contractors agree that the river sand, which is available today, is deficient in many respects. It does contain very high silt fine particles (as in the case of Filter sand).

Sometimes the presence of other impurities like coal, bones, shells, mica, silt, etc makes M–sand unfit for use in cement concrete, and due to weathering effect, this material decay which results in shortening the life of the concrete.

Nowadays, the government has implemented restrictions on river sand exploration and uses. Sand Mining from the river bed has a deep impact on the environment, as the water table goes deeper & ultimately dry.

General Requirements Ideal Sand

1. M-Sand particles should have a higher crushing value.

2. The surface texture of M Sand particles should be smooth and even.

3. The Particles should have a rounded shape.

4. The Percentage of fines below 600 microns in the sand should not be less than 3.

5. M sand should not contain any organic impurities.

6. Silt contained in M Sand should not be more than 2%, for crushed sand.

7. The number of fines below 75 microns shall not exceed 15% in M–Sand.

The Advantages of M Sand

More Cost-effective than Natural Sand

M–Sand manufacturing plant can be set up near the area of consumption, bringing down the cost of transportation and providing an assurance of consistent supply.

Compliant With the New European Standards

M-Sand can be used as aggregates in screed and concrete mixes, as per EN13139. As it can be utilized for blended mixture with natural sand.

Less Disruptive to the Environment

since the raw material for manufacturing M–sand is away from cities it is less environmental effect. Also, the use of sand can save natural river bed conditions, which is essential for any river.

Lesser Impurities and Good Working Properties

It is free of silt and clay particles and has denser particle packing than natural sand. M–sand has better tests like higher flexural strength, better abrasion resistance, higher unit weight, and lower permeability.

Disadvantages of Manufactured Sand

Workability Issues

M–Sand is come up with coarse classification and angular texture than natural sand, which is smooth and rounded due to natural gradation. To overcome this we have added more amount of cement to achieve the expected workability, leading to increased costs.

Larger Proportion of Micro Fines

M–Sand contains a large number of fine particles, this is due to its manufacturing process. The excessive fine can affect the strength and workability of concrete.

Manufactured Sand Price

M sand price is around 800 to 1000 rs. per tonne in India.

Expert Opinion

It is a proven fact that the concrete manufactured with M Sand performs better than concrete with natural sand as the property of crushed sand is better than that of natural sand. M-Sand is environmentally friendly as it replaces natural sand. The cost of concrete made up of M-Sand is less than concrete made with natural sand. Also, Govt. has to encourage the use of M-Sand to save river natural bed strata.
