How Nanotechnology Can Change the
Concrete World
Nanotechnology is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials.
Traditionally, nanotechnology has been concerned with developments in the fields of microelectronics, medicine and materials sciences. However, the potential for application of many of the developments in the nanotechnology field in the area of construction engineering is growing. In this paper a broad overview of the potential application of various nanotechnology developments in the construction engineering field is discussed, and the potential for further basic research that may lead to improved systems is evaluated.
APPLICATION OF NANOTECHNOLOGY IN
CONSTRUCTION:
Nanotechnology can be used for design and construction processes in many areas since nanotechnology generated products have many unique characteristics. These include products that are for: Lighter structure; Stronger structural composites e.g. for bridges etc ; Low maintenance coating ; Improving pipe joining materials and techniques ; Better properties of cementitious materials ; Reducing the thermal transfer rate of fire retardant and insulation ; Increasing the sound absorption of acoustic absorber ; Increasing the reflectivity of glass.
Nano with concrete;
The new steel was developed with higher corrosion-resistance and weld ability by incorporating copper nanoparticles from at the steel grain boundaries. Sandvik NanoflexTM is new stainless steel with ultra-high strength, good formability, and a good surface finish developed by Sandvik Nanoflex Materials Technology. Due to its high performance, Sandvik NanoflexTM is suitable for application which requires lightweight and rigid designs.
Its good corrosion and wear resistance can keep life-cycle costs low. Attractive or wear resistant surfaces can be achieved by various treatments (Sandvik Nanoflex Materials Technology). MMFX2 is nanostructure-modified steel, produced by MMFX Steel Corp
CONCLUSIONS
• Nanotechnology is a rapidly expanding area of research where novel properties of materials manufactured on the nanoscale can be utilized for the benefit of construction infrastructure
• A number of promising developments exist that can potentially change the service life and life-cycle cost of construction infrastructure.
