What is Nanotechnology?

Nanotechnology is the art and science of

manipulating matter at the nanoscale

One nanometre (nm) is one billionth

of a metre, or one millionth of a millimetre.A human hair is 80,000nm thick.

A red blood cell is 5,000nm in diameter.

A DNA molecule is 2.5nm wide.

10 hydrogen atoms arranged side by sidemeasure 1nm.

Concrete is a mixture of cement, sand(fine aggregate),

coarse aggregate and water.

As concrete is most usable material in constructionindustry its been require to improve its quality.

Nanotechnology can modify the molecular structure of

concrete material to improve the material properties.

CONCRETE

Concrete is the most important structural

material.

Because of that, concrete must be durable.

If we dont use steel or iron, how can

concrete be durable?


10/36

In Istanbul University, theres a running to setup Magnetic Field Laboratory

Because of magnetism, we can not use steelor iron in our concrete.

Carbon Nanotubes can take the place ofsteel and iron.

While concrete is stronger, at the same time

we preserve laboratory from damage ofmagnetism.

Nano silica and clinker used to increasedensification and hence mechanical

properties and durability of

cementitious materials.

Service life can be doubled through theuse of nano-additive viscosity

enhancers which reduce diffusion of

harmful agents in concrete (patent

pending).

Photocatalytic TiO2 added to concrete

to reduce carbon monoxide and NOx

emissions on roadways.

Cuore concrete is the first nano product that replaced the

micro silica with nano silica. Cuore concrete surpassed theexpectations 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 inorder to achieve compressive strengths of 80MPa, now only 1 day

is required.

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.

mechanics of the everyday cross over

TiO2: is a white pigment and can be used as an excellent

reflective coating. hydrophilic and therefore gives self

concrete to glass. anti-fogging coatings or self-cleaning

Carbon Nanotubes


18/36

Carbon Nano Tubes(CNT): Carbon nanotubes are a form of carbon thatwas first discovered in 1952 in Russia (and mostly ignored) and then re-discovered

in the 1990s 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.

Carbon nanotubes (CNTs) as a proxy for

polymeric chemical admixtures .

In 2004, Lab tests and production tests proved thatthe 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.

American Iron and Steel Institute and the U.S. Navy started to

develop new, low carbon, high performance steel (HPS) for

bridges in 1992 [10]. 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 SandvikNanoflex 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 wearresistant surfaces can be achieved by various treatments

(Sandvik Nanoflex 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 steelreinforcement 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 SteelCorp.).
