What Is Nanotechnology

“Nanotechnology is the art and science ofmanipulating matter at the nanoscale”

What is Nanotechnology?

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 MaterialsCarbon Nano Tubes(CNT)NANO-SILICATiO2TiO2 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.

NANOTECHNOLOGY And STEEL

Need For Nanotechnology In Steel..

• High Strength Steel Cables• High strength bolts• Temperature restriction
