In 2025 Holcim turned over CHF 15.724 billion in net sales, with recurring EBIT of CHF 2.876 billion, a margin of 18.3% and more than 45,000 employees. It is one of the largest cement and ready-mix concrete producers in the world.

Its own concrete admixture plant only started up in July 2026, in Córdoba, Argentina — a little over USD 1.2 million invested, 7 million litres of annual capacity.

Those two numbers together are the right starting point for understanding this group's admixture business: until that moment, a group this size bought essentially all of its admixtures in.

This one is written for people who make admixtures. Because Holcim plays a double role in your world — it is one of the largest consumers of admixtures anywhere, and it is becoming the owner of part of the capacity. Knowing where its boundary sits matters more than knowing its size.

Update the map first: North America is no longer called Holcim

Before discussing the business, one piece of common knowledge needs correcting.

On 23 June 2025 Holcim completed the 100% spin-off of its North American business. The new company, Amrize, listed on the NYSE and the SIX Swiss Exchange. It booked USD 11.7 billion of revenue in 2024 and runs more than 1,000 sites with 19,000 employees across North America. Holcim US and Lafarge Canada stopped belonging to Holcim that day.

If your account list still says "Holcim USA", it now points at two different companies with two different procurement systems.

Post spin-off, Holcim is still headquartered in Zug, Switzerland, with operations concentrated in three regions:

  • Europe: around CHF 8.5bn of net sales, 17% recurring EBIT margin;
  • Latin America: around CHF 3.0bn, 30.6% margin — the highest of the three;
  • Asia, Middle East & Africa: around CHF 3.6bn, 24.6% margin.

The portfolio is still churning hard: 21 transactions closed in 2025, 18 of them acquisitions and three divestments (Jordan, Nigeria and Iraq). The Xella acquisition completed in June 2026, a majority stake in Peru's Pacasmayo was signed in December 2025, and an agreement to sell the Philippines business was signed in August 2026.

What it means for suppliers: Latin America carries the group's highest margin and its heaviest investment. New opportunities are unlikely to sit in Europe.

Where admixtures sit in this group: a cost item, not a product line

This is where most people misjudge. Holcim does not run an admixture brand sold into the open market — that is Sika's business, Mapei's, and Saint-Gobain's (Chryso / GCP / Fosroc).

By product line, Building Materials grew 5.1% organically in 2025 while Building Solutions reached CHF 5.85bn, down 1.6% organically (segment and group totals differ through eliminations). On Holcim's books an admixture is a cost line inside ready-mix concrete — and at the same time the lever that makes the concrete perform.

That positioning drives two consequences, both of which land on you:

  • First, it is extremely price-sensitive on PCE. Not out of meanness, but because the volumes are so large — unit price multiplied by global ready-mix volume makes a single percentage point real money.
  • Second, it has a captive base big enough to amortise a plant. Once bought-in volume passes a threshold, building a blending line clears the economic bar. Those 7 million litres in Argentina are exactly that logic taking physical form.

So you are not dealing with "a customer who needs some admixture". You are dealing with a customer doing the maths on whether to turn your step of the process into its own workshop. Those two mindsets produce very different deals.

Four tiers: how much does it actually make itself?

Laid out globally, Holcim's admixture footprint runs four tiers deep, and they differ enormously.

Tier 1: its own brand, sold openly

Colombia is the clearest case. Holcim's Colombian entity runs the ADI Admixture by Holcim line, sold to third parties rather than kept captive. In that country it is simultaneously the cement leader, the ready-mix leader and an admixture supplier — in head-on competition with independent admixture producers.

Tier 2: its own plants, captive only

Colombia has the Tocancipá admixture plant; Argentina has the new Córdoba ADI plant commissioned in 2026. The stated logic for the latter is blunt: produce in-house what was previously bought from third parties, to improve cost efficiency and productivity, and to round out a portfolio that already spans cement, concrete, aggregates and precast.

The local chief executive put it more plainly: the goal is to accompany the whole cycle of the works, not merely to be a cement supplier.

Tier 3: "additives" inside the mortar and adhesives system

Across Argentina, Chile, Peru and Ecuador, Holcim holds brands such as Tector and Compaktuna. To be precise: this tier is adhesives, renders, repair and waterproofing products — not core polycarboxylate superplasticizer. Reading it as "Holcim already knows how to make PCE" is a misjudgement.

Tier 4: bought in, still open

In Europe, Africa and most of Asia, Holcim still buys admixtures externally. In markets like France these products mostly feed its own ready-mix network, but purchasing is decided centrally at group level — the door is at the group, not at the individual batching plant.

What scale is 7 million litres?

Seven million litres is roughly 7,000 cubic metres; at typical liquid admixture density that lands around 7,000 tonnes.

One step further: at a standard dosage of about 1% on finished admixture, 7,000 tonnes supports something like 700,000 tonnes of cementitious material — which translates to concrete in the order of 2 million cubic metres.

For calibration: Horcrisa, the ready-mix business Holcim Argentina bought for USD 32 million in March 2025, operates seven plants in greater Buenos Aires with 1.2 million m³ of annual volume. In other words, this admixture line is not a pilot facility — it can absorb a substantial share of national demand on its own.

Keep half your scepticism, though. Captive lines usually cover the high-volume, formula-stable, general-purpose segment first. High-performance, special-climate and low-carbon-tailored products stay bought in for a long time.

What it means for suppliers: do not read "the customer built a plant" as "this customer is gone". The right question is — how far along the chain does his line reach, and who supplies the part beyond it?

The counter-evidence: it has a plant, and still imports polycarboxylate

This is the section worth remembering.

Holcim in Colombia has both the Tocancipá plant and the ADI brand. By rights it should be one of the markets least in need of outside supply.

Yet import records show Holcim Colombia still buying polycarboxylate superplasticizer from South Korea — the shipment describes a high-range water reducer at 50–60% polycarboxylate salt content, clearing through the port of Cartagena.

That single record draws the true boundary of captive capacity:

  • In-house capacity solves the standardised, high-volume part, competing on fixed cost spread over volume;
  • High-performance, extreme-climate and low-carbon-tailored products still get bought outside;
  • In short, captive capacity displaces the general-purpose slice of external purchasing — not all of it.

What it means for suppliers: your opening is not "I am cheaper than his own plant" — that road is short. It is the stretch his line cannot reach, or cannot reach economically.

Why Latin America is the main theatre

Holcim's vertical integration — cement → ready-mix → admixture — keeps landing in Latin America first, for a simple reason: at a 30.6% margin, the region earns the investment.

  • Argentina: roughly USD 300m invested cumulatively; the Horcrisa ready-mix acquisition for USD 32m in March 2025; the admixture plant commissioned in July 2026.
  • Peru: a run of local acquisitions from 2024 to 2026, plus the Pacasmayo majority stake signed in December 2025 — Pacasmayo alone reported about USD 0.6bn of net sales in 2025.
  • Colombia: after acquiring a competitor's assets in March 2026, its concrete capacity moved to second in the country, with more than 20 ready-mix plants.
  • Ecuador: national ready-mix leader, and commissioning a new calcined-clay production line.

What it means for suppliers: Latin America is where captive conversion runs fastest — and therefore where the mother-liquor opportunity is largest. Once they build blending lines, they need to buy mother liquor steadily. The link they cut out of their own chain is exactly the one you can supply.

The low-carbon line is rewriting admixture specifications

This is the most substantive variable of the next few years, and it has not registered with most suppliers yet.

In 2025 ECOPact low-carbon concrete reached 31% of ready-mix net sales (26% the year before); ECOPlanet reached 36% of cement net sales (34%). Construction demolition material recycled rose 23.5% to 8.0 million tonnes. The group has targeted 1 million tonnes of calcined-clay cement in 2026 with dedicated lines in several European countries, and has already validated net-zero concrete with a negative carbon footprint using biochar.

What does that mean for polycarboxylate?

Decarbonisation changes the binder itself: calcined clay, recycled fines, biochar, mineralised materials. Each supplementary cementitious material has different surface chemistry, water demand and adsorption behaviour. Conventional PCE drifts on water reduction, slump retention and dosage in these new systems.

Put plainly: a formula validated yesterday does not necessarily hold in a low-carbon mix. Whoever first delivers mother liquor tuned to high SCM loadings — calcined clay in particular — opens a genuine technical window.

One more signal worth noting: several of Holcim's main plants in Ecuador have used a carbon-nanotube concrete additive at scale since 2024, a non-PCE route. "Advanced admixture" does not have only one answer, and leading concrete producers are willing to try new ones.

Three routes — pick by your position

  • If you sell PCE mother liquor or intermediates: the goal is not "replace his plant" but "become the feedstock supplier to his plant". A customer building captive blending capacity is structurally good news for mother-liquor sellers — once it runs, it needs stable, high-volume, batch-consistent supply, and that demand is far more predictable than spot buying. Negotiate on batch consistency and security of supply, not unit price.
  • If you sell finished admixtures: stay out of head-on competition in general-purpose products, where his scale wins. Work where his line cannot reach — high SCM loading, extreme climate (slump retention in heat, early strength in cold), special engineering (nuclear, tunnelling, mass pours). Higher unit price, smaller volume, and precisely the range a captive line does not justify.
  • If you provide technical service and formulation support: localised mix validation in Latin America is a clear gap. Local cement differs from what you are used to in mineralogy and in the type and level of its blended additions, so systematic cement-adaptation testing is mandatory before first supply; the shift to low-carbon binders then creates a fresh round of adaptation demand. This is the stickiest route in.

Risk list: the cost of dealing with a group this size

  • Captive conversion is one-way. Once an in-house line runs, the general-purpose external share only shrinks. Planning around one major customer's commodity volumes as a long-term base carries real risk.
  • Purchasing is highly centralised. Decisions sit at group or regional level; individual batching plants have little or no buying authority. Getting onto the approved-supplier register takes time, and compliance and technical files must be prepared well in advance.
  • The portfolio churns. Jordan, Nigeria and Iraq were divested in 2025; a Philippines sale was signed in 2026; Russia went in 2022. The market you invest in can be sold in the next portfolio review, taking the buying entity with it.
  • North America changed hands. Since June 2025 the US and Canadian business belongs to Amrize — different counterparty, different contracts, different purchasing system.
  • Technology routes are diverging. Carbon nanotubes, CO2 mineralisation and biochar add non-PCE options. Keeping every egg in the polycarboxylate basket may not hold up over the long term.

One last point

Holcim is not a competitor in the admixture industry. It is one of the admixture industry's largest customers — and it is moving part of that purchasing into its own yard.

Seven million litres is not a large number in itself, but it marks a direction: captive capacity displaces the standardised, high-volume slice, while the high-performance, speciality and low-carbon-adapted slice keeps growing. The former is contracting; the latter is expanding.

Whether you are displaced or needed is decided not by your price but by which slice you sit in.
