Nanotechnology is the art and science of manipulating matter at the nanoscale
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 Cuore concrete is the first nano product that replaced the micro silica with nano silica. Cuore concrete 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.
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.
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.
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
