10 hydrogen atoms arranged side by side measure 1nm.
What is actually happening? At the nanoscale, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter. At the nanoscale, the classical mechanics of the everyday cross over into the quantum mechanics of the nano-world
Nano Materials TiO2: is a white pigment and can be used as an excellent reflective coating. hydrophilic and therefore gives self cleaning properties to surfaces to which it is applied from concrete to glass. anti-fogging coatings or self-cleaning windows. see
Carbon Nano Tubes(CNT): Carbon nanotubes are a form of carbon that was first discovered in 1952 in Russia (and mostly ignored) and then re-discovered in the 1990’s in Japan. They are cylindrical in shape, as shown in figure below, and their name comes from their nanometre diameter. They can be several millimetres in length and can have one “layer” or wall (single walled nanotube) or more than one wall (multi walled nanotube). The Production cost of nanotubes is high and the price ranges from 20€ to 1000€ per gram depending on quality . It is being used to strengthen and monitor concrete.
NANO-SILICA In 2004, Lab tests and production tests proved that the nano silica did not contaminate, but it also produced better results than micro silica, and a liter bottle of the product was equivalent to a barrel full of micro silica, extra cement and super plasticizing additives. see
If we don’t use steel or iron, how can concrete be durable?
In Istanbul University, there’s a running to set up “Magnetic Field Laboratory” Because of magnetism, we can not use steel or iron in our concrete. Carbon Nanotubescan take the place of steel and iron. While concrete is stronger, at the same time we preserve laboratory from damage of magnetism.
Cuore concrete is the first nano product that replaced the micro silica with nano silica. Cuore concrete surpassed the expectations of its design and gave concrete not only the high initial and final resistance but in addition, plasticity, impermeability, and cement savings of up to 40%. Also, it lowered the levels of environmental contamination.In addition, a liter bottle of Cuore concrete equals a whole barrel of micro silica, extra cement and super plasticizers. If before a 2 meters thick beam was required to hold a bridge correctly, now only 75 cm are required. If before 28 days were necessary in order to achieve compressive strengths of 80MPa, now only 1 day is required.
American Iron and Steel Institute and the U.S. Navy started to develop new, low carbon, high performance steel (HPS) for bridges in 1992 . The new steel was developed with higher corrosion-resistance and weld ability by incorporating copper nanoparticles from at the steel grain boundaries. SandvikNanoflexTM is new stainless steel with ultra-high strength, good formability, and a good surface finish developed by SandvikNanoflex Materials Technology. Due to its high performance, SandvikNanoflexTM 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 (SandvikNanoflex Materials Technology).
MMFX2 is nanostructure modified steel, produced by MMFX Steel Corp. Compared with the conventional steel, it has a fundamentally different microstructure- a laminated lath structure resembling “plywood”. This unique structure provides MMFX2 steel with amazing strength (three times stronger), ductility, toughness, and corrosion resistance. Due to high cost, the stainless steel reinforcement in concrete structure is limited in high risk environments. The MMFX2 steel could be an alternative because it has the similar corrosion resistance to that of stainless steel, but at a much lower cost (MMFX Steel Corp.).

AWARDING NANOTECHNOLOGIC PAINT: NANSULATE BUILDER news Magazine 2008 Best Product Winner - "Energy Efficiency" category.Ultra Thin Industrial Grade High Performance Protective Insulation Coating. Nansulate is the first isolation paint in the world. It is introduced in 2004. It provides heat isolation with very thin layer. It's possible decreasing heat from 100°C to 70 ° C also thin as 200 micron layer. It's impossible to do this work with traditional methods.
The suggested thickness of layer for the buildings is 200 micron. The product shows full performance in two months. It’s more expensive than ordinary paint but if we assume that product as a isolation material, it’s cheapest method for jacketing.
Physical appearance of this paint is like a glass. It provides heat and corrosion isolation. There is no space in materials. So it is durable to external factors. Because of configuration of paint, oxygen doesn’t affect to internal structure. By this way we protect our materials from corrosion.
This isolation paint can be applicable to steel,aluminum and other different metal surfaces. This application procures perfect adherence on steel,aluminum,PVC,fiberglass,wood,concrete,plastic and much more surfaces. You can clean easily. You just need water and soap. Optionally can be painted.(Other colors) High heat range between -40 °C and 240 °C Least 10% energy saving.
PHOTOCATALYSIS Photocatalysis is the substance that provides reaction with the light. Photocatalysis’s active all the time although it is exposed to sunlight.TiO2 is the best example for phocatalysis. It can clean and refresh itself by force of sunlight or the things that spread light.
SOLUTION OF SELF CLEAN OUT SURFACE LAYER AIM: Protection from UV beam and stop the biologic growing. Surface cleans itself from exhaust fumes. SOLUTION: Nanophotocatalysis layer is combination of nanotechnology and photocatalysis. This overlap is applicated easy on the surface, so there are different perfect properties on building surface. It provides clean appearance.It decrease the cleanup and cure cost.
PROPERTIES: Easy and self cleaning. Protection from UV damages. Super hydrophility. Air purify. Anti bacterial and anti sooty moulds. Anti-static surface. BENEFITS: Nanophotocatalysis layer separates organic dirt. It prevents the splash after the rain. It decreases energy consumption for frigorific in summer season. It restrict the growing algae, sooty moulds.
