A considerable area in which incremental nanotechnology keeps up with growing consumer demands is the construction industry. Although a wide range of nano-based products are already available on construction markets, state-of-the-art applications are in the process of being developed or sometimes close to market launch. Nanotechnology equips this sector with extraordinary improved properties such as mechanical strength, durability, antibacterial resistance, self-cleaning ability, energy conservation, and thermal insulation, to name but a few, leading to a revolution in constructing modern, safe, and inexpensive buildings, railways, dams, airports, and roadways. Therefore, manufacturers, authorities, and researchers all over the world have focused on the development of novel products, some of which are waterproof coatings for stone, wood, metal, and glass; nanocomposites insulated with aerogel to stop thermal losses; antibacterial floors, tiles, and paints; long-lasting concretes, cements, and primers; and efficient heat storage. Titanium dioxide, zinc oxide, and carbon nanotubes are the most common nanomaterials, which have been commercialized in the construction industry. Furthermore, similar to other areas, the construction industry is in desperate need of a new paradigm to reduce pollution and wastes during production processes. In this regard, nanotechnology facilities present some panaceas by which the construction industry is being more environmentally-friendly; clean; sustainable; and resistant to pollution, algae, fungi, and graffiti.
Nano-based products of the construction industry are classified into the following subdivisions:
1. Structural materials including block, concrete, cement, steel, and rebar.
2. Masonry materials/Building materials including brick, thatch, plaster, filler, primer, tile, flooring, mosaic, stone, glass, and panel.
3. Paints and pastes
4. Coatings based on thermal insulating, glass protective, heat protective, corrosion protective, self-healing, self-cleaning, anti stain, anti fingerprint, degreying, and waterproof solutions
5. Chemicals such as seeds, bioadhesive, scratch resistant additives, additives for asphalt and concrete.
The keywords used to build up the construction industry nanoproducts database are as follows: Nano + Solutions, coatings, wood, stone, paste, paint, glass, thatch, tile, mosaic, concrete, cement, sand, plaster, filler, thermal insulator, sound insulator, wax, composite panel, asphalt, additive, adhesive, photocatalytic solutions, self-cleaning solutions, and corrosion protective solutions.
