Research cutoff: · Updated:The binder behind concrete
Cement is the fine binder that reacts with water and holds aggregates together in concrete. Concrete is the resulting composite material, rather than another name for cement. That distinction is essential when interpreting an industry whose output is frequently discussed alongside housing, roads, and other construction. A cement-production figure measures the manufactured binder, not the quantity of concrete placed or the number of buildings completed. s4
Iran has a substantial cement industry. The USGS country report records finished cement separately from clinker and identifies both domestic consumption and exports. Its account of 2024 names Iraq, Kuwait, Afghanistan, Russia, and Pakistan among destinations for combined cement-and-clinker exports. Those combined shipments should not be described as exports of finished cement alone. s2
[s2] [s4]Why clinker matters
The manufacturing sequence starts with preparing and blending mineral raw materials. High-temperature processing creates clinker, the hard intermediate material that is cooled and then ground with gypsum and other appropriate ingredients to produce cement. Gypsum helps control setting behavior. An integrated plant therefore performs a different range of operations from a works that only grinds purchased clinker. s3
Raw-material chemistry influences the blend and the process. Calcium-bearing materials such as limestone are combined with sources of silicon, aluminum, and iron. During processing, limestone decomposition releases carbon dioxide; fuel combustion provides another source of emissions. Cleaner electricity alone cannot eliminate the carbon dioxide released by the mineral reaction. This is a chemical distinction, not an estimate of emissions at any particular Iranian plant. s3s5
[s3] [s5]From mineral inputs to cement
The diagram separates clinker production from cement finishing. It shows the general material sequence, without implying that every Iranian works carries out every stage.
[s3]A fluctuating production path
The historical series below retains the observations and revision flags in a single USGS country-report table. It shows growth followed by a setback and recovery, rather than uninterrupted expansion. The final observation is the highest in this particular five-year window. Output alone does not establish profitability, construction demand, or the cause of any annual change. s1
A newer USGS summary supplies estimates through 2025. These appear in a separate dataset because they are a different statistical release with rounded estimates. The country report's more detailed 2024 figure and the summary's rounded estimate are not identical; neither has been silently substituted into the historical chart. s2s6

Data, units and methodology
Transcription of the Cement, hydraulic row in Table 1 of the USGS Iran 2023 country report. Original reporting-year labels and thousand-metric-ton units are retained. The table includes information available through January 6, 2025 and identifies reported values unless otherwise marked. Revised observations retain the source's r flag. Gregorian boundary dates are left null because underlying producer reporting periods were not independently harmonized. This dataset preserves one source vintage rather than merging later summary estimates.
| Reporting period | Hydraulic cement production (metric tons; ×1000) |
|---|---|
| 2019 | 60,400 observed — Reported value; stored in the source's thousand-metric-ton units.[s1] |
| 2020 | 68,300 observed — Reported value; stored in the source's thousand-metric-ton units.[s1] |
| 2021 | 62,700 revised — Marked r for revised in this source vintage.[s1] |
| 2022 | 64,200 revised — Marked r for revised in this source vintage.[s1] |
| 2023 | 71,400 observed — Reported value; stored in the source's thousand-metric-ton units.[s1] |
A five-year source vintage is presented rather than a fully reconciled 15-year history.
Later reports may revise earlier values; this chart is explicitly labeled by its source vintage.
The table does not provide sufficient detail to independently reconcile every underlying producer reporting period.
| Reporting period | Cement production, USGS summary estimate (metric tons; ×1000) |
|---|---|
| 2024 | 71,000 estimated — Source estimate rounded as published; distinct from the more detailed country report's 2024 figure.[s6] |
| 2025 | 68,000 estimated — Source estimate, not a final audited national production total.[s6] |
Capacity and environmental performance need separate evidence
Production capacity describes potential annual throughput under stated assumptions, while production describes material actually manufactured. USGS reports both for Iran, and also separates cement from clinker. Their figures answer different questions and should not be added together or treated as equivalent measures of demand. s2
Energy and emissions add another layer. Kiln heat is central to making clinker; grinding and handling are additional operations. Dust control addresses particulate emissions, while reducing carbon dioxide requires attention to fuel use and mineral chemistry. Process references explain these mechanisms, but they cannot prove the performance of an Iranian factory without local measurements. The industry's clearest assessment therefore combines correctly defined output with plant-level operating and environmental evidence. s3s5

limitations
- The historical country-report table and newer summary estimates retain separate release identities.
- USGS PDF passages and tables were inspected through indexed source text because direct PDF fetches were blocked; visual inspection of those USGS pages was not completed.
- General manufacturing references do not establish individual Iranian plant technology, emissions, or present operating status.
- Sources were accessed on 2026-10-28 for a research cutoff of 2026-10-26; no post-cutoff event is asserted.
data gaps
- The preferred 15-calendar-year window through 2026 was sought, but a fully reconciled comparable series for that entire interval was not established.
- The historical chart retains five comparable observations from one table; newer 2024–2025 estimates are presented separately.
- No full-year 2026 production value is supplied.
- Plant-level emissions, provincial output, and current operating interruptions were not established.
