In the realm of construction, materials like timber and steel have always dominated the scene.
Each, with its unique properties, has shaped the way we build and live. Today, with environmental concerns at the forefront, the focus is shifting towards sustainable construction, and nanotechnology is proving to be a game-changer.
Grand View Research valued the global nanomaterials market at USD 10.88 billion in 2022, anticipating a 14.8% CAGR from 2023 to 2030.
They stated, “The U.S. government invests heavily in nanotechnology with the motive of becoming a global power and to lead technological advancement across the globe.” This investment underscores the significance of nanotechnology in future innovations.
Nanotechnology in Modern Construction Materials
Nanotechnology is providing tangible upgrades to established materials in the construction industry.
Timber, known for its sustainability and carbon sequestration, has been bolstered against environmental threats with the incorporation of nanotechnology. Coatings enriched with alumina and silica nanoparticles not only shield the material but also provide enhanced UV resistance. This protective measure parallels innovations seen in metals used in construction.
Steel’s inherent strength has been amplified with nanoparticle-infused coatings, leading to the advent of the corrosion-resistant MMFX variant. The journey towards robustness doesn’t end with metals; foundational materials, like concrete, are also evolving.
Nano-silica’s integration into concrete results in denser compositions, increased durability, and heightened water resistance. Alongside concrete, even the venerable brick is getting a nanotech upgrade.
By blending in nano-clays, bricks enjoy enhanced compressive strength, ensuring they stand the test of time. As for adhesives, innovations are relentless. Mortars now benefit from nano-clay enhancements, providing superior moisture resistance while contributing to global energy-saving endeavors.
Startups Pioneering Nanotechnology in Construction
In the innovative realm of construction, nanotechnology is ushering in a revolution, with various startups leading the charge.
NanoPhos is a standout startup using nanotechnology in construction materials. They develop smart materials that adjust their properties based on external conditions, addressing challenges like moisture and mould. Their offerings enhance surfaces like tiles and walls, improving energy efficiency in construction. Branching into marine coatings via a subsidiary, the company’s innovations are the brainchild of Greek researchers, with products made in Greece.
Another noteworthy venture is Dena Nano Wood. This startup taps into the potential of nanotechnology by recycling end-of-life tires (EOLT) and repurposing waste thermal materials. The result? Rapidly assembled, cost-effective housing solutions that are ideal for disaster-stricken or challenging terrains.
Building on this momentum, GoNano emerges as yet another innovator in the sector. Their forte lies in offering construction materials that are enhanced by nanotechnology. Particularly, their catalogue boasts of nano-augmented wood and concrete surfaces, showcasing the limitless possibilities of this technology in the construction world.
Conclusion
Nanotechnology is not merely an advancement; it’s a paradigm shift in how we perceive and execute construction. As startups and innovations continue to flourish, one thing is certain: nanotechnology holds the blueprint for a more resilient and sustainable future in construction.
