NANOTECHNOLOGY IN CIVIL ENGINEERING BY: SHYAM SHUBHAM 08DDCE011
What is Nanotechnology? “Nanotechnology is the art and science of manipulating matter at the nanoscale”
INTRODUCTION • Nanotechnology is not a new science and it is not a new technology. • Nanotechnology is an enabling technology that allows us to develop materials with improved or totally new properties • Nanotechnology is the use of very small particles of material. A nanometer is a billionth of a meter.
NANOTECHNOLOGY IN CONCRETE • Concrete is a mixture of cement, sand(fine aggregate), coarse aggregate and water.As concrete is most usable material in construction industry it’s been require to improve its quality. • Nanotechnology can modify the molecular structure of concrete material to improve the material properties.
Introduction To Nano Materials • Carbon Nano Tubes(CNT) • NANO-SILICA • TiO2 • TiO2 In Concrete:TiO2 is a white pigment and can be used as an excellent reflective coating.it is hydrophilic and therefore gives self cleaning properties to surfaces to which it is applied.
High Strength Steel Cables • High strength bolts • Temperature restriction Need For Nanotechnology In Steel..
