Market Driver

"Increased Infrastructure Spending in Developing Economies"

Governments across Asia-Pacific, Middle East, and Africa are scaling up infrastructure investments, which is creating a steady demand for durable and cost-effective construction materials.

For instance, in April 2025, the U.S. Department of Transportation approved a USD 150 million federal grant to fund a new roadway and Port of Entry facility in the San Diego–Baja California border region.

The Otay Mesa project will establish a modern border crossing east of the existing Otay Mesa Port of Entry, with the goal of improving transportation flow and supporting trade efficiency in the region.

The supplementary cementitious materials market benefits from these investments, as blended cements provide long-term performance in bridges, highways, dams, and tunnels. These materials reduce permeability and improve resistance to aggressive environments, making them suitable for large-scale infrastructure exposed to harsh conditions and extended lifespans.

Market Challenge

"Inconsistent Quality and Availability of Raw Materials"

A significant challenge hindering the growth of the supplementary cementitious materials market is the inconsistent quality and limited availability of raw materials such as fly ash and slag. Supply depends heavily on industrial by-products, which vary by source and region. This can impact performance in concrete applications.

To address this, key players are investing in advanced processing technologies, setting up dedicated blending units, and forming partnerships with energy and steel producers. These efforts help ensure a more stable and uniform supply, improving product consistency and enabling broader use across construction projects.

Market Trend

"Advancements in Blended Cement Technology"

Technological progress in cement formulation and processing is emerging as a notable trend in the supplementary cementitious materials market, enabling their integration into high-performance concrete.

New milling and activation techniques are improving the reactivity of pozzolans and slags, making them more efficient in concrete mixes. The market is benefiting from innovations that enhance strength development, setting time, and workability, allowing broader adoption in both precast and on-site construction applications.

In November 2024, Limak Cement and Air Liquide successfully conducted the first test of hydrogen-blended fuel at the Limak Cement plant in Ankara. Building on the positive results, Limak Cement plans to expand its use of alternative fuels with high biogenic content and renewable energy by 2030. The company continues its partnership with Air Liquide to further advance the integration of hydrogen technology in cement manufacturing.

Supplementary Cementitious Materials Market Regional Analysis

Based on region, the market has been classified into North America, Europe, Asia Pacific, Middle East & Africa, and South America.

Supplementary Cementitious Materials Market Size & Share, By Region, 2024-2031 The Asia Pacific supplementary cementitious materials market share stood at around 35.05% in 2024, valued at USD 8.97 billion. Asia Pacific has a strong base of thermal power plants and steel manufacturing units, particularly in rapidly industrializing areas.

These facilities generate fly ash and slag in large volumes, which are increasingly being processed and commercialized for use in blended cement. The ready availability of these by-products has created a stable and scalable supply chain for supplementary cementitious materials.

Moreover, several countries in the region have introduced environmental certification systems and construction mandates promoting the use of sustainable building materials. The shift is generating a demand for blended cements that include supplementary cementitious materials, leading to widespread adoption in commercial, industrial, and residential projects.

The North America supplementary cementitious materials industry is estimated to grow at a CAGR of 6.57% over the forecast period. North America is investing heavily in the repair and modernization of critical infrastructure, such as highways, water systems, and airports.

These projects require concrete that can withstand freeze-thaw cycles, chemical exposure, and heavy loads, which is boosting the demand for supplementary cementitious materials.

In August 2024, the U.S. Department of Transportation announced the 22nd Street Revitalization project in Tucson, which will replace a deteriorating bridge originally built in the 1960s. The new bridge will extend over the Union Pacific Railroad and State Route 210. Backed by a USD 25 million RAISE grant, the project also includes widening 22nd Street from four to six lanes with a divided median, along with the addition of a separate bridge for bicycle and pedestrian traffic.

Furthermore, several cement companies in North America are modernizing or building new terminals that can blend supplementary materials at the distribution point. The expanded blending capacity is improving market accessibility and fostering the use of supplementary cementitious materials across various construction segments.

Regulatory Frameworks

The U.S. regulates SCMs primarily through ASTM International standards. ASTM C618 governs fly ash and natural pozzolans, ASTM C989 covers ground granulated blast-furnace slag, and ASTM C1240 pertains to silica fume. ASTM C1709 offers guidance for alternative SCMs. Additionally, federal policies such as the Infrastructure Investment and Jobs Act and California’s Buy Clean California Act promote low-carbon construction, indirectly supporting wider SCM use in concrete applications.
The European Union regulates SCMs under harmonized standards, including EN 197-1 (common cement), EN 450-1 (fly ash), and EN 15167-1 (ground granulated blast-furnace slag). These standards define chemical, physical, and performance properties for use in concrete. The European Green Deal and the Fit for 55 legislative package drive policy integration, prompting construction stakeholders to adopt wider SCM for public procurement and climate-neutral building initiatives.
Japan’s SCM regulations are defined by national standards developed by the Japanese Industrial Standards Committee (JISC). SCMs such as fly ash, silica fume, and slag are widely accepted in construction to improve concrete durability, particularly in earthquake-prone zones. The Building Standard Law also requires performance verification, promoting the use of SCM. Japan’s Ministry of Land, Infrastructure, Transport and Tourism actively supports these materials for their role in long-lasting, low-maintenance infrastructure.

Competitive Landscape

Major players in the supplementary cementitious materials industry are increasingly focusing on expanding their production and distribution facilities to strengthen their regional presence and meet growing demand.

This strategy supports more efficient supply of supplementary cementitious materials to large infrastructure projects, particularly in high-density urban areas. Such facility expansions help companies improve logistics, reduce delivery timelines, and ensure consistent material availability across both local and national construction sectors.

In April 2025, Eco Material Technologies inaugurated the Blissville Rail Terminal located in Queens, New York. This facility is designed to handle around 50,000 tons of fly ash annually, sourced from the company’s nationwide network, to serve infrastructure developments across the New York metropolitan region. The terminal utilizes rail transport to deliver fly ash and other cementitious materials, which can substitute up to 25% of traditional Portland cement in conventional concrete formulations.
