The demand for limestone in Manipur is likely driven by all of the above.
Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). It is the most common sedimentary rock in the world and is found in a variety of colors, including white, gray, brown, and black. Limestone is used in a variety of industries, including the cement industry, agricultural use, and road construction.
The cement industry is the largest consumer of limestone. Limestone is used in the production of cement, which is a key ingredient in concrete. Concrete is used in a variety of construction projects, including buildings, roads, and bridges.
Agricultural use is another major driver of demand for limestone. Limestone is used as a soil amendment to improve soil pH and fertility. It is also used as a liming agent to reduce the acidity of soil.
Road construction is another major driver of demand for limestone. Limestone is used in the production of asphalt, which is a key ingredient in road construction. Asphalt is used to pave roads, highways, and parking lots.
In conclusion, the demand for limestone in Manipur is likely driven by all of the above: the cement industry, agricultural use, and road construction.
