Nanotechnology for Construction Industry
Nanotechnology has the potential to significantly alter material properties, resulting in better performance and novel usefulness.
In the building sector, nanotechnology offers a wide range of uses. Nanotechnology has the potential to improve the primary properties of traditional construction materials (e.g. concrete), add functionality to existing materials (e.g. paints/coatings or glass could gain self-cleaning, antimicrobial, and pollution-reducing properties), and introduce ‘‘new" materials to meet existing needs.
The use of nanoparticles in cementitious materials can help to increase structural efficiency, durability, and strength, as well as the quality and lifetime of constructions. The usage of nanoscale industrial waste-based cement substitutes can help to minimise CO2 emissions from concrete production.
Structure stability can be achieved using nanotechnology by analysing a variety of measurements from sensors such as displacement transducers, accelerometers, strain gauges, and temperature sensors, which provide an array of real-time data that can be continuously monitored from a central location to provide detailed insight into the state of a structure.
Because of the surfaces' superhydrophobicity, only a small amount of water is required to create a very thin, continuous film using nanomaterials, resulting in surfaces that can reduce air conditioner use and associated energy consumption, as well as reduce heat island phenomena common in cities and urban areas.
Arising nanotechnology-based MEMS sensors have additionally further developed capacities and sensitivities. MEMS sensors can either be surface mounted or installed in substantial construction itself and the sensors can be utilized for nonstop estimation and checking of the strain in structures.
Antimicrobial nanoparticles in the form of antimicrobial coatings can prevent ‘‘sick building syndrome," in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, and ‘‘building related illness," in which illnesses are attributed directly to airborne building contaminants.
The incorporation of nanoparticles to concrete creates smart concrete that meets the needs of structural sensors. They can detect a wide range of stresses/strains and the response is reversible with no detrimental impact on structural parameters like compressive strength, flexural strength, or ductility.
Self-cleaning hydrophobic paints have the potential to save money in the construction industry by lowering maintenance costs for building walls and facades. Hydrophobic coatings can also be used to limit the buildup of snow and prevent the formation of ice on solid surfaces, which could be useful on roadways and windows in areas where the temperature is below 0 degrees Celsius.
Solar paints" can be easily applied to a conductive surface and generate electricity when exposed to light. Solar paint can be used in solar cell glazing because it is efficient, inexpensive, and simple to apply. This type of glazing combines the transparent/ translucent qualities of glass with the solar energy harvesting capabilities of solar cells.
For use in building, self-cleaning products based on the idea of hydrophilicity have been commercialised. Tiles, glass, aluminium cladding, plastic films, tent materials, cement, and other superhydrophillic self-cleaning surfaces are available. Self-cleaning glass and self-cleaning tent materials are widely utilised in bus and train terminals, sports centres, park sunshades, and other places.

How Nanotechnology Is Bringing Change
The thoughts and ideas driving Nano Science and nanotechnology began with a discussion named "There's Plenty of Room at the Bottom" by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology on December 29, 1959, some time before the term nanotechnology was utilized.
