Abstract: This research aims at Comparative experimental behavior of Halloysite Nano Tubes& Clay as an in –fill to Composite Steel tubes. Both materials are of Nano category and one is in the tubular form and the other amorphous. Naturally formed in the Earth over millions of years, Halloysite Nano Clay are unique and versatile Nano materials that composed of aluminum, silicon, hydrogen and oxygen and are mined from natural deposits in countries like China, New Zealand, America, Brazil, and France. The effects of the diameter, length of steel tube, grade of concrete & volume fractions of HNC’s to concrete (0%,0.5%,1%,1.5%,&2%) on the behavior of Halloysite Nano Clay(HNC’s) concrete filled steel tube columns under axial compression are presented and compared with that of Nano tubes. Also, Studies are carried out to know the effect of Diameter (D), Change in steel tube length (l), and Strength of infill (fCK) and to determine the ultimate load (Pult) & defection (?axial) in HNC’s composite steel hollow tubes under monotonic loading and SEM (scanning electron microscope) image are taken during mixing, before testing and after testing and Fracture Analysis will be carried out for the buckled steel tubes using Radiographic Testing

Keywords: Halloysite Nano Clay1, SEM2, Fracture Analysis3.
