Peak Cement, Falling Concrete: When Volume Stops, Price Is the Entire Market

Three markets, one event. Cement grows 86.3 per cent on price. Ready-mix concrete grows 113.4 per cent on price while volume subtracts 10.4 per cent. The bag that carries the cement grows 4.15 per cent in value on material volume of 1.35 per cent — for a customer whose own tonnage has already peaked.

Run those three together and a single sentence describes the entire construction materials chain: the volume stopped, and price became the whole market.

The cement side: a market that has already peaked and knows it

The tonnage series is unambiguous. 3,900 million tonnes in 2024 — revised down from an earlier 4,000 — and 3,800 million in 2025. The downward revision matters more than the decline, because it says the peak was lower than the industry believed while it was happening.

Against that, 86.3 per cent of the market’s value growth to 2033 is price. Not a majority: 86.3 per cent. Strip the price effect out and the industry is a flat 3.8-billion-tonne business with a carbon liability attached to every tonne of it.

This is not a story about an industry failing. It is a story about an industry that has successfully converted a volume business into a price business, which is a much better outcome than the alternative. The global cement market is growing in value on tonnage that will never grow again, and doing it in a way that its shareholders have largely been paid for.

The internal composition of that growth tells you where the durability sits. CEM I shrinks 1.31 per cent while CEM II grows 43.03 per cent, and CEM II’s share of the pair goes from 53.6 to 62.6 per cent. Price is carrying the market; specification is carrying the price.

The concrete side: the bridge that shows exactly where growth comes from

Ready-mix concrete is the cleaner demonstration because the decomposition can be run to the dollar. Of the total value increase, volume contributes a negative USD 7,563 million, price contributes positive USD 82,539 million, and interaction subtracts USD 2,151 million. That sums to USD 72,825 million against an actual movement of USD 72,827 million — a two-million-dollar rounding difference across a 72-billion-dollar bridge, which is as close to a proof as this kind of arithmetic gets.

So price is 113.4 per cent of the growth and volume is minus 10.4 per cent. The ready-mix market is not growing because more concrete is being poured. It is growing because a cubic metre costs more, at the same time as the number of cubic metres falls from 3,953 to 3,850 million.

And the price engine that produced this is visibly spent in the market that ran it hardest. US producer prices rose 13, 13, 8 and 4 per cent in four consecutive years — 43.4 per cent compounded — on volume that fell 1.59 per cent. Four straight halvings. Meanwhile Titan America’s realisation rose 1.2 per cent while its aggregates volume rose 36.5 per cent, and CRH put USD 2.1 billion into supplementary cementitious materials rather than into batching capacity.

That is what a company does when it has decided the price lever is finished. It stops buying the thing it was raising the price of and starts buying the inputs to the thing it will sell next.

The packaging side: a value story bolted to a volume decline

The bag market is where the whole chain’s arithmetic becomes visible, because the bag’s customer is the cement tonne and the cement tonne is not growing.

28.89 billion bags at twenty to the tonne carry about 1,444.5 million tonnes of cement — 38.0 per cent of world output — and the packaging bill for a USD 90 tonne of cement is USD 3.77, or 4.19 per cent. Nobody optimises 4.19 per cent. The cement packaging market grows 4.15 per cent in value against material volume growth of 1.35 per cent, and the gap between those two numbers is price and mix rather than more bags.

Downstream, the same pattern repeats with sharper numbers. Industrial paper sacks grow 4.68 per cent in value on paper volume of 1.60 per cent — a specification object rather than a larger number of sacks, against a customer, European cement, that is 57 per cent of deliveries and walking away. Woven polypropylene sacks grow 3.17 per cent in count while the polymer behind them grows 1.79 per cent, because the average sack falls from 88 to 79 grammes. Two different markets wearing one number.

And then the deletion. FIBC and bulk bags are 1.9 per cent of units and 34 per cent of the polymer, and they carry the tonnage of 48.6 billion 25-kilogramme sacks — 75.7 per cent of the entire 64.2-billion sack market — at 2.63 times the cost per tonne of the sacks they replace, and they win anyway. Because the substitution is not price-led. It deletes the bag count, the pallet and the labour.

Every one of those four markets is growing in value while the physical thing it sells is growing more slowly or shrinking. That is the same event as the cement and concrete numbers, observed three steps further downstream.

Why this is one event and not five coincidences

The volume peak is a policy outcome. Chinese output fell from 3.29 to 2.288 billion cubic metres of concrete between 2021 and 2025 — 30.5 per cent — and Chinese cement demand followed it. That removed more volume from the world market in four years than the rest of the world added. No forecast that assumed trend construction growth survived contact with it.

Price replaced it, everywhere, at once, because every market in this chain was running the same playbook: pass cost inflation through, consolidate the local competition, and harvest the margin while the volume base was still big enough to absorb it. It worked. It is now approaching its limit, and the limits are visible in the same place in every market — a halving increment, a flat realisation, a gap between unit growth and material growth that is getting wider.

What replaces price

Two things, and neither of them is a demand recovery.

Specification. The whole chain moves value from the undifferentiated tonne to the formulated one. Cement from CEM I to CEM II. Concrete out of standard structural mix, which falls from 64.1 to 49.0 per cent of value. Bags from a sack to a declared, barrier-coated, plot-audited packaging component. In each case the price stops being readable off a screen, and that is the entire commercial prize.

Conversion. The ready-mix market sits at 31.62 per cent of the world’s concrete, against 67 per cent in Europe and above 80 per cent in the United States. Every point of conversion is volume taken from a site mixer and given to a batching plant, and it is created by municipal prohibition rather than by construction activity. It is also the single most destructive force in the bag market, because a silo does not use bags.

The question no filing answers

Everything above is visible in published data. What is not visible anywhere is whether price can keep carrying the market — whether the next turn of price exists in a given producer’s territory, or whether the customer’s own economics have closed it.

That is precisely the question this programme’s primary layer exists to answer, and it is the reason the secondary record alone is insufficient here. A filing tells you what was realised. It does not tell you what a commercial lead believes about the next twelve months, what a specifier will accept, or whether a procurement threshold will arrive before a price increase does. Those are conversations, and they are weighted as evidence rather than quoted as attribution.

The chain has already done the hard part. It converted a volume business into a price business and got paid for it. The next conversion — into a specification business — is the one that decides who is still earning a margin in 2033, and it is happening in tender documents rather than in price announcements. That is where to look.

The pieces this draws on

Each argument in this synthesis is developed in full elsewhere in the cluster.

• The Cement Industry Is Retiring Its Own Cheapest Substitutes — why the cheapest route to a lower clinker factor has a supply ceiling.
• CEM I Shrinks While CEM II Adds the Growth — the product mix as the only growth in a flat market.
• China’s Register Is the Ceiling — where the volume peak actually came from.
• Carbon Stopped Being a Cost and Became a Price — the EUR 48 a tonne that makes the mix decision financial.
• There Is No World Price for Concrete — why the global average is a blend of two unrelated numbers.
• Sand Is the Binding Input — the 63.33 per cent of the product nobody prices.
• The American Concrete Price Engine Has Run Out of Road — the halving increments that end the price cycle.
• Ireland Told Public Bodies to Stop Buying CEM I — the regulator that concrete cannot avoid.
• The 31.6 Per Cent Gap — conversion as the only volume engine left.

About the method

This article is the synthesis piece for a seven-report cluster and draws on 70 per cent secondary and 30 per cent primary sources across all of it. The secondary layer is public and primary: national cement and concrete output series, product-level market data by cement type, producer weighted-average price series and company results disclosures, association returns on ready-mix penetration, and the CBAM regulation as published. The primary layer is structured fieldwork with producers, batching-plant managers, specifiers and procurement leads on whether price has further to run and where margin is expected to come from instead; it is weighted into the conclusions as evidence about commercial intent rather than quoted as individual attribution. All arithmetic in this article — the 86.3 per cent price contribution in cement, the USD 7,563 million volume, USD 82,539 million price and USD 2,151 million interaction bridge against USD 72,825 million, the 113.4 and minus 10.4 per cent contributions, the 43.4 per cent compounded US price rise and 1.59 per cent volume decline, the 28.89 billion bags and 1,444.5 million tonnes and 4.19 per cent of a USD 90 tonne, the 48.6 billion sack equivalent at 75.7 per cent and 2.63 times cost, and the 31.62 per cent ready-mix share — was computed deterministically from the published inputs. No third-party market-research estimate is used, and no competing research provider is cited.
