補助セメント系材料（SCM）市場シェア分析、業界動向と統計、成長予測 2026-2031年

補助セメント系材料（SCM）市場は、2025年の279億6,000万米ドルから2026年には296億7,000万米ドルに成長し、2026年から2031年にかけて年平均成長率6.12%で2031年には399億米ドルに達すると予測されています。この拡大は、政府が炭素価格制度を施行し、公共事業が低炭素コンクリートの義務付けを導入する中で、建設部門が持続可能な建築慣行へと急速に移行していることを反映しています。サウジアラビアの1兆1,000億米ドル規模のビジョン2030パイプラインなどのインフラ投資プログラムの加速は、石炭燃焼副産物の減少に伴いセメント業界がクリンカー含有量を削減する必要性と相まって、補助セメント系材料（SCM）に対する持続的な需要を生み出しています。焼成粘土、火山性ポゾラン、石灰石混合セメ​​ントにおける供給側のイノベーションは、フライアッシュやスラグの供給量減少を緩和する一方、フラッシュ焼成技術は処理に必要なエネルギーを最大40%削減し、利用可能な原料基盤を拡大する。

セグメント分析

• 石炭生産量の減少にもかかわらず、フライアッシュは確立された物流ネットワークと予測可能なポゾラン特性に支えられ、2025年には補助セメント系材料市場で41.72%の市場シェアを占めると予測されています。高炉生産量が減少する中でも、高炉スラグセメント（GGBFS）は高性能コンクリート分野への供給を続けています。一方、焼成粘土は、フラッシュ焼成炉の普及によりエネルギーコストが削減され、カオリナイト含有量がわずか15～25%の粘土でも経済的に加工できるようになったことから、年平均成長率（CAGR）6.88%で拡大しています。この傾向は、焼成粘土を減少する石炭由来資源の主要な代替品として位置づけ、地域的な供給ポートフォリオを再構築し、豊富な鉱物資源を背景にした新規参入企業を誘致するでしょう。
• メーカー各社は、超精密な粒度制御が可能な専用焼成・粉砕プラントへの投資を強化しており、ポゾラン反応性指数を800 mg Ca(OH)₂/g以上に高め、高価格を実現している。シリカフュームと高反応性メタカオリンは、超高性能コンクリートにおいてニッチな役割を維持している一方、石灰石フィラーはポルトランド石灰石セメントの世界的な展開を支え、段階的な脱クリンカー化プロセスを強化している。これらの動向は、産業廃棄物の機会主義的な利用から、計画的かつ拡張可能な補助セメント系材料（SCM）市場生産戦略への転換を示唆している。
• 補助セメント系材料（SCM）市場レポートは、SCMの種類（フライアッシュ、スラグセメント、シリカフュームなど）、エンドユーザー（住宅建設、商業・公共施設、工業施設など）、材料形態（粉末、スラリー／懸濁液など）、および地域（アジア太平洋、北米、ヨーロッパ、南米、中東・アフリカ）別にセグメント化されています。市場予測は金額（米ドル）で示されています。

Supplementary Cementitious Materials Market Analysis

The Supplementary Cementitious Materials market is expected to grow from USD 27.96 billion in 2025 to USD 29.67 billion in 2026 and is forecast to reach USD 39.9 billion by 2031 at 6.12% CAGR over 2026-2031. This expansion reflects the construction sector’s rapid shift toward sustainable building practices as governments enforce carbon-pricing schemes and public-sector projects embed low-carbon concrete mandates. Accelerating infrastructure investment programs—such as Saudi Arabia’s USD 1.1 trillion Vision 2030 pipeline—collide with the cement industry’s need to reduce clinker content amid dwindling coal-fired by-products, creating durable demand for SCMs. Supply-side innovation in calcined clay, volcanic pozzolans, and limestone-blended cements mitigates the shrinking availability of fly ash and slag, while flash-calcination technology lowers processing energy requirements by up to 40% and broadens the viable feedstock base.

Global Supplementary Cementitious Materials Market Trends and Insights

Boom in Global Construction and Infrastructure Spending

Massive public-works funding underpins the supplementary cementitious materials market, with India’s infrastructure capital expenditure swelling 5.7 times to USD 36.1 billion in 2023-24, Saudi Arabia’s Vision 2030 exceeding USD 1.1 trillion, and African infrastructure outlays averaging USD 93 billion each year. These programs specify higher SCM substitution in concrete—Sydney Metro achieved 38–52% replacement, resulting in a 120,000-tonne CO₂-e reduction across projects . The construction surge, therefore, multiplies SCM demand, enabling suppliers to secure long-term contracts that justify investments in flash-calciner capacity and logistics optimization.

Stricter CO₂-Emissions Regulations and Carbon-Pricing Schemes

Regulatory pressure is intensifying. France’s RE2020 caps embodied carbon in new buildings at 640–740 kg CO₂-e/m², while the EU’s Carbon Border Adjustment Mechanism prices imports on a carbon basis. US Buy Clean rules require Environmental Product Declarations for federally funded concrete, and California applies carbon pricing to construction materials, creating premium markets for high-SCM mixes. These regulations make decarbonized concrete economically attractive, locking in structural demand for SCMs as a compliance pathway.

Dwindling Supply of Quality Fly Ash and Slag as Coal and BF Steel Decline

Coal-power output in the U.S. has fallen 60% since 2010, slashing high-grade fly ash volumes, while blast-furnace slag shrinks as steel producers pivot to electric arc furnaces. Remaining ash stockpiles command a 40-60% price premium, and transport distances lengthen, eroding cost advantages. Concrete producers must therefore re-engineer mix designs around alternative SCMs or pay higher inputs, constraining short-term growth until new supply sources mature.

Other drivers and restraints analyzed in the detailed report include:

• Rapid Adoption of Blended/Green Cements
• Government Green-Procurement Incentives
• High Variability in SCM Quality/Specifications

Segment Analysis

Fly ash held a 41.72% market share of the Supplementary Cementitious Materials market in 2025, supported by well-established logistics networks and predictable pozzolanic properties, despite declining coal generation. Slag cement (GGBFS) follows, supplying high-performance concrete segments even as blast-furnace output contracts. Calcined clay, however, is expanding at a 6.88% CAGR as flash-calciner units proliferate, lowering energy costs and enabling economic processing of clay with only 15–25% kaolinite. This trajectory positions calcined clay as the primary substitute for dwindling coal-derived sources, restructuring regional supply portfolios and inviting new entrants backed by mineral-rich deposits.

Manufacturers are funneling capital toward purpose-built calcination and grinding plants capable of ultraprecise particle-size control, raising pozzolanic reactivity indexes above 800 mg Ca(OH)₂/g and drawing premium pricing. Silica fume and high-reactivity metakaolin maintain niche roles in ultra-high-performance concrete, while limestone filler underpins the global rollout of Portland Limestone Cement, reinforcing incremental de-clinkerization pathways. Collectively, these trends signal a pivot from opportunistic use of industrial waste toward deliberate, scalable supplementary cementitious materials market production strategies.

The Supplementary Cementitious Materials Report is Segmented by SCM Type (Fly Ash, Slag Cement, Silica Fume, and More), End User (Residential Construction, Commercial and Institutional, Industrial Facilities, and More), Material Form (Powder, Slurry/Suspension, and More), and Geography (Asia-Pacific, North America, Europe, South America, and Middle East and Africa). The Market Forecasts are Provided in Terms of Value (USD).

Geography Analysis

The Asia-Pacific region remains the epicenter of the supplementary cementitious materials market, capturing 47.88% of the 2025 value, driven by China’s continued but moderating construction activities and India’s surge in infrastructure expenditure to USD 36.1 billion during 2023-24. Ready access to coal ash and blast-furnace slag once underpinned low-cost supplies; however, environmental policies are accelerating coal retirements, prompting regional cement majors to prioritize calcined-clay hubs near kaolinite-rich deposits. ASEAN economies are leveraging Belt and Road funding to build transport corridors that require high-SCM concrete volumes, while Japan and South Korea are deploying premium metakaolin blends in seismic-resistant and marine infrastructure.

The Middle East & Africa is projected to post the fastest 6.42% CAGR through 2031, underwritten by Saudi Arabia’s NEOM, the Red Sea Project, and regional mandates for low-carbon materials. UAE’s Estidama and Egypt’s green-building codes codify SCM thresholds, attracting investment in volcanic-ash processing in East Africa and calcined-clay projects throughout the Sahel. Logistics hurdles and quality assurance gaps impede immediate scale-up; however, mineral abundance positions the region for self-sufficiency once the processing infrastructure matures. North America faces a tightening fly-ash pipeline after 60% coal-generation decline, driving exploration of natural pozzolan sources in Nevada and Utah, alongside increased slag imports from Europe. Federal Buy Clean rules and state-level tax credits reward early adopters of high-SCM mixes, keeping demand buoyant despite supply friction. Europe, with mature carbon-pricing and RE2020 building codes, pushes technical boundaries by integrating limestone-calcined clay and recycled fines at industrial scale, cementing its role as a decarbonization laboratory. South America, though smaller, gains momentum as Brazil’s coastal resilience projects and Chile’s mining infrastructure demand durable, low-carbon concrete, stimulating regional pozzolan and rice-husk ash ventures that gradually connect into global supply chains.
