Building materials: Value chain, from upstream to the customer
Cement, concrete, bricks, tiles, glass and gypsum board made from quarried minerals
Value chain, from upstream to the customer
Criticality to the chain: 5 · Chokepoint 4 · Critical 3 · Important 2 · Supporting 1 · Commodity service Stage 1 Quarrying and raw materialsHold mining leases and extract limestone for cement and crushed stone and sand for concrete, selling by the tonne within a short haul radius.
Why supporting: Many quarries compete locally, though limestone leases near a plant are fixed and river sand bans can cause local shortages. Technologies Drilling and blasting Mobile crushing and screening Manufactured sand plants Mine planning software Depends on Commodities Stn Crushed stoneAgg Sand & gravelKao Kaolin & clays Chemicals AN Ammonium nitrate Energy Oil Crude oilExp Explosives and propellants Industries Machinery and equipmentExamples: Holcim, Vulcan Materials, CRH, Heidelberg MaterialsCoal power stations and steel mills sell fly ash and granulated slag, and gypsum producers sell set-retarder gypsum, to cement and concrete makers.
Why important: Blended cements depend on these by-products, and supply moves with coal plant and steel mill output rather than cement demand.

Why important: Many producers nationally, but freight costs make markets regional, and in India the top two hold about 43% of capacity (calculated), so local supply can be tight.

Why critical: Only a handful of specialist firms, mainly European and Chinese, supply full cement lines, and new lines take two to three years.

Why critical: A float line costs hundreds of millions of dollars and runs non-stop for 15 years, so a few groups dominate each market.
