MATERIALS / TECHNOLOGY / INVESTING Concrete built the world. Now it needs a revolution.

A vast market. A new generation of technology. And a question investors should ask: who will create more value from every tonne?

The next industrial opportunity may be beneath our feet.

Before a data center can run its first AI model, somebody has to build its foundations. Before an airport welcomes passengers, somebody has to pour its runways. Concrete quietly connects the digital economy to the physical world.

That makes this a story about far more than cement. Better materials can help us build housing, roads, bridges and energy infrastructure with less waste and greater confidence. The opportunity is to improve an essential product at enormous scale.

GCCA’s 2021 roadmap cited about 14 billion cubic meters of concrete a year. At an illustrative density of 2.4 tonnes per cubic meter, that implies roughly 34 billion tonnes. This is a scale benchmark, not a fresh 2026 production count. Concrete is the most-used human-made material by volume; that does not make it the largest industry by revenue.

Scale benchmark: GCCA, October 2021 roadmap announcement. Mass conversion: TIC illustration; density varies by mix.

01 / FOLLOW THE MONEY A trillion-dollar estimate. A much bigger question.

There is no single audited global concrete-revenue total. One useful benchmark is ready-mix: concrete batched for delivery to construction sites.

Fortune Business Insights estimates $1.081 trillion for 2025 and $1.172 trillion for 2026. Its 2034 projection is $2.389 trillion. These are third-party market estimates, not reported global company sales, and other studies can use different definitions and methods.

Know which market you are measuring.

Adding cement and ready-mix sales can double-count value. The sector’s size is not a small technology supplier’s addressable market.

Market figures and methodology: Fortune Business Insights — Ready-Mix Concrete Market. No categories have been added together.

02 / WHY IMPROVEMENT MATTERS We need smarter concrete.

GCCA attributes roughly 7% of global CO₂ emissions to the cement and concrete sector. The breakthrough investors want would lower delivered cost, cut emissions, improve durability and make schedules more predictable. Today’s solutions address parts of that challenge; none reviewed here proves a universal 30% cut in total project cost.

New technology and better integration are both needed. Certification, feedstock supply and reliable industrial output decide whether a promising idea becomes a durable business.

Evidence: CarbonCure ready-mix; Heidelberg CCS; Sika/Giatec; GCCA 2025/26 report. Company claims are identified.

03 / FROM TONNES TO VALUE What would 10%, 20% or 30% really mean?

Imagine a $100 million construction project. A genuine improvement across the entire budget would be powerful. But the denominator matters: saving money on concrete is different from saving the same percentage on the whole project.

Scenario only. These percentages are not demonstrated project savings from the technologies described in this edition.

Start with the actual cost structure.

Suppose concrete-related materials and work account for $15 million of the budget. A 20% reduction in that scope saves $3 million, or 3% of total project cost. It does not save $20 million. The 15% cost share is an assumption, not an industry average.

If better strength monitoring or a different construction method also brings completion forward, the developer may reduce financing and site overhead. For example, two months less on a $50 million average financed balance at 8% annual interest saves approximately $667,000, using simple interest. Whether the project can actually finish earlier must be demonstrated.

Combine that hypothetical financing benefit with the $3 million scope saving and the total is about $3.67 million, or 3.7% of the project budget. Add only independently measured benefits: avoid counting the same labor, overhead or timing saving twice.

Who gets paid when concrete gets better?

Developers gain from lower budgets and earlier use. Contractors can gain from less rework and efficient execution. Manufacturers benefit if reduced inputs outweigh energy, equipment and licensing costs. Technology owners can earn through licensing, software, additives or partnerships.

A solution earns its place through measurable customer value. Longer life and lower maintenance add potential benefits; test them in a discounted lifetime-cost comparison with explicit repair assumptions.

All project and financing calculations in this section are TIC hypothetical scenarios. CarbonCure’s 3–5% cement-content claim in the technology section is a separate, narrower measure.

04 / SEVEN WAYS TO OWN THE SECTOR Who is already on the market?

Seven listed businesses offer different routes into the story. Group revenues include products beyond concrete; a big company is not automatically a technology leader.

05 / WHERE WE WOULD START Three stocks. Three reasons to pay attention.

Our editorial order is CRH, Heidelberg Materials, then Amrize. CRH offers the strongest balance of scale, operating evidence and valuation in this focused shortlist. Heidelberg provides the clearest large-company technology case; Amrize adds regional growth. This is a research priority, not a claim of guaranteed outperformance.

³ Stock Analysis snapshots checked October 9. Forward P/E uses estimates; EV/EBITDA and FCF yield use the provider’s trailing definitions. They differ from company-adjusted EBITDA. Ratios can update independently of the price table.

01 CRH — The established leader

Growth and profitability: 2025 sales rose 5% and adjusted EBITDA rose 11%. Q2 2026 revenue grew 6%; the company retained its $8.1–$8.5B full-year adjusted EBITDA outlook. Innovation: investment in Sublime gives exposure to a new process alongside an existing materials business. Valuation: about 14× forward earnings is lower than Vulcan’s roughly 26×, although their mixes and margins differ.

02 Heidelberg Materials — The technology opportunity

Growth and profitability: FY25 revenue rose 1.4%; RCO reached €3.4B and free cash flow €2.1B. Innovation: Brevik and evoZero demonstrate industrial deployment. Valuation: the lowest forward P/E in our three-stock screen is attractive enough for further work, but low multiples alone do not establish undervaluation.

03 Amrize — The growth candidate

Growth and profitability: Q2 2026 revenue grew 8.6% to $3.494B. Innovation: the attraction is a scaled regional platform and product execution, rather than a proven proprietary cement breakthrough. Valuation: about 13.6× forward earnings makes the growth case worth examining; its broader building-envelope exposure changes the comparison.

06 / THE NEXT CHAPTER The next winner may own the recipe.

Imagine concrete that is cheaper to use, easier to schedule, more durable and more sustainable. Its value could come from patents, a recurring additive, software or a license for every tonne produced. The idea is exciting. The business model makes it investable.

Watch the innovators — and the route to public markets.

CarbonCure already supplies carbon-mineralization systems. Sublime Systems is scaling an electrochemical cement process; CRH and Holcim announced $75M in combined investment in 2024. Brimstone is developing a silicate-rock process that co-produces cement and other materials. These are private companies, not directly purchasable listed stocks. Their claims and scale-up plans should not be treated as proven full-scale economics.

Established producers may license a process, invest in a developer or acquire it. They bring distribution, plants and customer relationships; newcomers can bring intellectual property. Investors should ask for repeat orders, standards approval, costs at industrial scale and cash generation after capital spending. A partnership is evidence of interest, not proof of meaningful future earnings.

Our verdict: there is reason for hope in an industry that can improve housing, mobility and infrastructure together. Start with businesses that can fund change, then follow the evidence. The future is about creating more value from every tonne.
