Question

Explain the factors which affect the location of cement industry.

Answer 1

Factors Affecting the Location of the Cement Industry:

• Raw Material Availability

  • Cement production requires large quantities of raw materials, especially limestone, which forms 60-65% of the product. On average, 1.5 tonnes of limestone are needed to produce one tonne of cement. Consequently, cement factories are usually located near limestone deposits to reduce transportation costs.
  • Other raw materials include silica (20-25%), alumina (5-12%), gypsum (for setting regulation), sea shells, and slags from steel and fertilizer plants.
  • Coal is essential not only as a fuel but also in the chemical process to produce clinker. Around 250 kg of coal is required per tonne of cement.

• Transport

  • Cement and its raw materials are heavy and low-value bulk materials, so transportation over long distances is costly. Locating plants close to limestone sources and/or near markets helps reduce transport cost.
  • Beneficiation at quarry heads can reduce limestone transport costs.

• Power Supply

  • Cement manufacturing consumes a lot of power, mainly during grinding and kiln operations. Modern plants use 80-90 units of power per tonne of cement, down from older plants requiring 120-130 units.
  • Reliable and economical power supply is crucial, as coal forms about 40% of the production cost.

• Market Proximity

  • Ready markets facilitate quick disposal of heavy products like cement and reduce transportation expenses. Proximity to construction markets is vital.

• Other Factors

  • Economic factors such as capital availability and government policies influence industry location but are secondary to raw materials and transport.
  • Climate and availability of land and water also play roles but are less critical than raw materials and transport.
