Supply. Kolkata cement comes mainly from the Chhattisgarh (Baloda Bazar) and Jharkhand belts plus eastern-region grinding units; TMT is well-supplied from the SAIL/Bhilai and local eastern mills, and aggregate is railed in from Jharkhand and Odisha quarries since the Bengal delta has no hard rock. For sand & aggregates specifically, this places Kolkata broadly in line with the national cost band — the page's table reflects close to the 50-city national average.
What moves the local price. the alluvial Ganga-delta geology means zero local stone — all coarse aggregate bears a long rail/road haul, structurally lifting concrete cost; river sand from the Damodar and Rupnarayan is available but increasingly regulated.
Buyer takeaway. steel is a relative bargain here owing to the SAIL/Bhilai supply chain, but aggregate carries one of India's higher haulage premiums — staging stone at a Howrah/Dankuni rail siding is the standard cost-control move for big pours. Cross-check the sand & aggregates ranges in the table above against a live local quote before raising a purchase order — the spread between bulk-dealer and retail rates in Kolkata, West Bengal is wider than the table's midpoint suggests.
Fine and coarse aggregates per IS 383:2016 together occupy 60-75 % of the volume of concrete. Fine aggregate (sand) is either river sand (natural) or manufactured sand (M-sand, produced by crushing stone). Coarse aggregates are graded stone chips — 10 mm, 20 mm, and 40 mm nominal sizes are standard. For a typical M20 mix, each m³ of concrete needs ~0.45 m³ of sand and ~0.9 m³ of 20 mm coarse aggregate. Quality matters: silt content, water absorption, flakiness, and grading all feed into mix design per IS 10262. Most Indian cities have banned mechanised river-sand extraction since 2013-2016, making M-sand the default for RCC.
Aggregate prices in India vary wildly by proximity to a quarry — coastal and hilly cities pay 2-3× the quarry-gate price due to transport. M-sand has overtaken river sand as the default in south India since 2020; north India and east India still lean on river sand where legally extracted. 2024-25 saw ~8-12 % price rise on diesel cost inflation and stricter mining enforcement. Kerala and the north-east remain the most expensive regions due to haul distance.
