Self-Consolidating Concrete Market size is forecast to reach US$14.6 billion by 2026, after growing at a CAGR of 6.8% during 2021-2026. SCC stands for self-consolidating or self-compacting concrete, which has a moderate viscosity, high segregation resistance, high deformability, and low yield stress. Self-consolidating concrete is a highly fluid mix with unique characteristics such as closely matching the texture of the mold, not requiring tamping after pouring, being closely related to self-leveling, and easily flowing through obstructions and formwork. It is often processed using raw materials such as limestone powder, silica fume, air entrainment, metakaolin, and more. Furthermore, pouring self-consolidating concrete requires less labor than traditional concrete mixes. All these advantages are majorly driving its market growth. The rapidly growing building and construction sector have increased the demand for durable and environment-friendly concrete; thereby, fueling the self-consolidating concrete industry growth.
Despite the government's efforts to put the construction industry at the center of its recovery plans, the Covid-19 pandemic posed a threat to the industry. The manufacturers of self-consolidating concrete were stranded on raw materials such as limestone powder, silica fume, air entrainment, metakaolin, and more due to a major effect on the logistics industry due to the lockdown in the COVID-19 area. This led to a shortfall in the supply of self-consolidating concrete from producers resulted in a significant demand-supply gap. Furthermore, the financial crisis caused much of the economy to shut down, forcing governments large and small to postpone construction activities, causing road, bridge, and tunnel projects to crumble. For instance, in March 2020, The Pennsylvania Department of Transportation suspended all road and bridge construction projects (such as Route 20 Bridge Rehabilitation in Erie County, Cambridge Springs (Route 6) Bridge Replacement in Crawford County, and more) until further notice in response to the ongoing coronavirus (COVID-19) pandemic. All these factors accumulatively limited the self-consolidating concrete market growth during the pandemic.
Self-Consolidating Concrete Market Segment Analysis – By Raw Material
The admixture segment held the largest share in the self-consolidating concrete market in 2020 and is forecasted to grow at a CAGR of 6.2% during 2021-2026, owing to its resistance or stability to segregation of the plastic concrete mixture. It's done by increasing the total amount of fines in the concrete and/or adding admixtures that change the viscosity of the mix. When the grading of available aggregate sources cannot be optimized for cohesive mixtures or when source variations are large, additives that affect the viscosity of the mixture are especially useful. With less cementitious materials content and/or admixture dosage, SCC can be achieved with a well-distributed aggregate grading. Companies are introducing SSC-related products and solutions. Grace Construction Products, for example, has introduced the ADVA® 400 Admixture Series, which offers unprecedented rheology control, materials management, and moisture control for consistent ready-mix self-consolidating concrete (SCC) manufacturing.

Self-Consolidating Concrete Market Segment Analysis – By End-Use Industry
The infrastructure segment held the largest share in the self-consolidating concrete market in 2020 and is forecasted to grow at a CAGR of 12.5% during 2021-2026. In comparison to traditional methods such as shotcrete, self-consolidating concrete is a relatively new technology that offers high flow rates, bonds well have low permeability, and provides smooth surfaces. Self-consolidating concrete can also be used in tight spaces and to match a structure's existing geometry. And, as a result of these benefits, self-consolidating concrete (SCC) has grown in popularity in the infrastructure construction industry in recent years. SCC is used in a wide range of applications, including slabs, elevated decks, thin and radiant floors, columns, bridge pier repair and rehab, and full-depth precast bridge deck panels. Unlike traditional concrete, which uses the largest aggregate size possible to reduce the amount of paste required, SCC uses smaller aggregate, ranging from 10 to 14 millimeters in size. SCC possesses high fluidity that easily conforms to a formwork's shape and high resistance to segregation and bleeding, owing to which it is being preferred over other concrete types.
Self-Consolidating Concrete Market Segment Analysis – By Geography
Asia-Pacific region held the largest share in the self-consolidating concrete market in 2020 up to 48%, owing to the flourishing building and construction industry in the region, which is accelerating the demand for self-consolidating concrete in the region. The construction industry is booming in China and India, with a huge amount of money flowing in. It is expected to change significantly in the forecast period, particularly in India, owing to the development and implementation of SCC by various companies. The construction industry accounts for a significant portion of India's GDP. As a significant contributor to India's GDP, the industry serves as a springboard for new opportunities. For illustration, the Government of India announced in June 2019 that the Project Monitoring-Invest India Cell (PMIC), which was established to expedite large infrastructure projects by the Centre, has so far resolved 615 of the 1,038 projects that came under its review, with an estimated investment of Rs 22.35 trillion. SSC is being used in major construction projects across the Asia Pacific. SCC was used to build the New Station of Chinese Centre Television, a significant landmark in Beijing. Furthermore, SCC was used to construct the Railway Underbridge over Boundary Street in Roseville, New South Wales, Australia, with ballast aggregates and a high dose of supplementary cementitious materials to minimize the heat of hydration. These projects in the Asia-Pacific region are accelerating the demand for self-consolidating concretes in the region, thereby driving market growth.
Self-Consolidating Concrete Market Drivers
Significant Reduction in Overall Cost of the Constructed Site
In recent years, the concept of self-compacting concrete (SCC) as a building material has gained widespread acceptance. Self-compacting concrete is less expensive to make than traditional concrete. The labor required to place and finish self-leveling, self-consolidating concrete is reduced. It reduces screeding and eliminates mechanical vibration. Noise is reduced in precast production settings when vibration is eliminated. Also, by reducing the overall need for vibration equipment and formwork, SCC lowers capital and maintenance costs. As a result, the self-compacting property of self-compacting concrete eliminates the need for vibrations, resulting in a lower manpower requirement for placement. In some cases, the labor required can be cut in half when compared to conventional concrete. The use of self-compacting concrete eliminates the need for energy, which would otherwise be used to carry out vibration processes. Furthermore, because it saves labor, accelerates project schedules, reduces noise, addresses environmental concerns, and ensures reduced equipment wear and tear, the use of self-compacting concrete results in lower maintenance, repair, and overhauling costs. As a result, the cost-saving benefits of self-compacting concrete are propelling the global self-compacting concrete market forward.
Increasing Infrastructural Projects
Self-compacting concretes can compact into every corner of formwork using only their weight, eliminating the need for vibrating compaction. Thus, they are extensively used in the infrastructure construction industry to ensure durable concrete structures, independent of the requirement of skilled workers. For instance, Mexico's government unveiled a private-sector initiative in November 2019 to revive the flagging economy by investing nearly 859 billion pesos (US$44 billion) in the development of infrastructure. According to the plan's details, 72 projects were completed in 2020, and another 41 are scheduled to be completed between 2021 and 2024. The ‘Infrastructure Investment Program' of Australia's federal government is expected to deliver US$57.5 billion in infrastructure funding between 2026 and 2027, including funding for the US$7.7 billion “National Rail Program” and equity for other major infrastructure investments, increasing market demand. Hence, all such infrastructure projects and investments are likely to drive the demand for self-consolidating concretes from the infrastructural sector during the forecast period.
Self-Consolidating Concrete Market Challenges
High Cost Associated with Self-Consolidating Concrete Raw Materials
The high cost of self-compacting concrete is a significant impediment to the industry's growth. The high costs of raw materials used in the production of self-compacting concrete continue to limit their use in a variety of industries. For instance, admixtures are frequently expensive and may carry relevant ecological footprints, the reason why there are a growing necessity and interest in finding cheaper and more sustainable alternatives. The price increase is being motivated by escalating raw material costs. For instance, BASF increased its price for PCE-based polymers (raw material) for concrete admixtures in Europe in September 2018. With an increase in the raw material prices, an immediate impact is seen on the prices of admixtures. Thus, the high cost of self-consolidating concrete raw materials such as that of admixture poses a challenge for the self-consolidating concrete market growth during the forecast period.
