水中コンクリートの世界市場規模は2024年に1,846億米ドルに達しました。IMARC Groupは、2025年から2033年にかけての成長率(CAGR)は3.52%で、2033年には2,562億米ドルに達すると予測しています。同市場が著しい成長を遂げている主な理由は、海洋インフラプロジェクトの増加、混合設計の技術進歩、環境持続可能性への注目の高まりです。耐久性のある海洋構造物に対する差し迫ったニーズと環境に優しいコンクリートソリューションの革新が、市場成長に明るい見通しを生み出しています。
技術の進歩
水中コンクリートの技術的進歩には、性能や耐久性を大幅に向上させる混合設計や添加剤における様々なイノベーションが含まれます。このような改良には一般的に、加工性や硬化時間を向上させる特殊な混和剤の開発や、腐食や硫酸塩攻撃に対する耐性を強化する添加剤が含まれます。例えば、LSUの工学研究者たちは、50万米ドルのNational Science Foundation Future Manufacturing Awardの資金提供を受けた先駆的プロジェクトに取り組んでいます。このプロジェクトの主な焦点は、AI主導の材料モデリングとバイオベースの建設材料を使用した、水中建設用の積層造形法の開発です。
海洋インフラプロジェクトの増加
港湾建設、港湾開発、洋上風力発電所などの海洋インフラプロジェクトの増加は、水中コンクリートの需要を大きく促進しています。その卓越した耐久性と過酷な水中環境への耐性は、これらの用途に理想的なものとなっています。例えば、2023年10月、インド政府(GoI)は23000ルピー相当の海事プロジェクトを立ち上げ、ブルーエコノミーの長期ビジョン文書を発表しました。このプロジェクトは、港湾施設を強化し、持続可能な慣行を促進し、国際協力を促進することを目的としています。これらのイニシアチブは、インド海洋ブルーエコノミー向け「Amrit Kaal Vision 2047」に沿ったものです。さらに、首相は、海洋分野における世界的・国家的パートナーシップのために、7.16億ルピーに相当する300以上の覚書を締結しました。
環境持続性への注目の高まり
水中コンクリートにおける環境の持続可能性とは、建設プロジェクトの二酸化炭素排出量を最小限に抑えるために、環境に優しい材料や技術を使用することです。これには、再生骨材、低炭素セメントの代替品、耐久性を高め環境への影響を低減する革新的な混和剤などを取り入れることが含まれます。こうした持続可能な材料を利用することで、建設業界は温室効果ガスの排出を削減し、長期的な生態系のバランスを促進することを目指しています。例えば、ECOncreteと呼ばれるイスラエルの新興企業は、海洋生物を誘引し、沿岸構造物の二酸化炭素排出量を削減する、環境に優しいコンクリート製品を開発しました。自然の岩層を模倣し、生物多様性を促進することで、これらの製品は時間とともに強度を増し、従来のコンクリート製バリアに代わる持続可能な代替品となります。
The global underwater concrete market size reached USD 184.6 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 256.2 Billion by 2033, exhibiting a growth rate (CAGR) of 3.52% during 2025-2033. The market is experiencing a significant growth mainly due to the increase in marine infrastructure projects, technological advancements in mixed designs and the growing focus on environmental sustainability. The pressing need for durable marine structures and innovations in ecofriendly concrete solutions is creating a positive outlook for the market growth.
Technological Advancements
Technological advancements in underwater concrete involve various innovations in mixed designs and additives which significantly enhances performance and durability. These improvements generally include the development of specialized admixtures which increases workability and setting time as well as additives to enhance resistance to corrosion and sulfate attacks. For instance, LSU engineering researchers are working on a pioneering project funded by a $500,000 National Science Foundation Future Manufacturing Award. The main focus of the project is on developing additive manufacturing methods for underwater constructions using AI driven material modeling and bio-based construction materials.
Increasing Marine Infrastructure Projects
The increasing in the number of marine infrastructure projects, including port construction, harbor development, and offshore wind farms, is significantly facilitating the demand for underwater concrete. Its exceptional durability and resistance to harsh aquatic environments make it ideal for these applications. For instance, In October 2023, the Government of India (GoI) launched maritime projects worth Rs 23000 crore and unveiled a long-term vision document for the blue economy. The projects aim to enhance port facilities, promote sustainable practices and facilitate international collaboration. The initiatives are aligned with the 'Amrit Kaal Vision 2047' for the Indian maritime blue economy. Additionally, the Prime Minister dedicated more than 300 Memorandums of Understanding (MoUs) worth over Rs 7.16 lakh crore for global and national partnerships in the maritime sector.
Rising Focus on Environment Sustainability
Environmental sustainability in underwater concrete involves using eco-friendly materials and techniques to minimize the carbon footprint of construction projects. This includes incorporating recycled aggregates, low-carbon cement alternatives, and innovative admixtures that enhance durability and reduce environmental impact. By utilizing these sustainable materials, the construction industry aims to reduce greenhouse gas emissions and promote long-term ecological balance. For instance, an Israeli startup called ECOncrete has developed eco-friendly concrete products that attract marine life and reduce the carbon footprint of coastal structures. By mimicking natural rock formations and encouraging biodiversity, these products strengthen over time providing a sustainable alternative to traditional concrete barriers.
Aggregates accounts for the majority of the market share
Aggregates account for the majority of underwater concrete market share mainly due to their indispensable role in enhancing the strength, durability and stability of concrete used in marine environments. These materials including gravel, sand and crushed stones provide the necessary bulk and weight to the concrete mix which ensures that it can withstand the harsh conditions underwater. High quality aggregates helps in reducing the permeability and shrinkage of concrete which makes it more resistance to water and chemical attacks. The rising demand for robust and long-lasting marine infrastructure continues to drive the importance and market dominance of aggregates in underwater concrete application.
Hydropower holds the largest share of the industry
Hydropower holds the largest share of the underwater concrete industry due to its extensive use in dam construction, water reservoirs, and hydroelectric power plants. The need for durable and reliable underwater concrete is paramount in these projects to ensure structural integrity and longevity. The increasing global focus on renewable energy sources, particularly hydropower, drives demand for underwater concrete. These structures must withstand significant water pressure and environmental challenges, making specialized underwater concrete crucial. The expansion of hydropower infrastructure worldwide continues to solidify its dominant position in the underwater concrete market.
North America leads the market, accounting for the largest underwater concrete market share
The report has also provided a comprehensive analysis of all the major regional markets, which include North America (the United States and Canada); Europe (Germany, France, the United Kingdom, Italy, Spain, Russia, and others); Asia Pacific (China, Japan, India, South Korea, Australia, Indonesia, and others); Latin America (Brazil, Mexico, and others); and the Middle East and Africa. According to the report, North America represents the largest regional market for underwater concrete.
North America leads the underwater concrete market, accounting for the largest share due to significant investments in marine infrastructure, port expansions, and the maintenance of aging structures. For instance, in April 2024, the US government announced a major $20 billion plan to revitalize the country's maritime infrastructure. This substantial investment is set to modernize American shipyards, boost domestic crane manufacturing, and improve port facilities, solidifying the nation's standing in international maritime operations. The region's advanced technological capabilities and stringent environmental regulations drive innovation in concrete formulations, enhancing durability and sustainability. Additionally, the growing focus on renewable energy projects, such as offshore wind farms, further boosts demand. The presence of major construction companies and ongoing infrastructure development projects solidify North America's dominant position in the underwater concrete market, driving continuous growth and technological advancements.
