Experimental Investigation on Steel Columns Infilled With Halloysite Nano Tubes
Mr. Hafeez Khan, Dr. N. S Kumar
Abstract :
Concrete filled steel tubes have been extensively used in the modern Structure mainly due to the combination of the advantage of Steel tube & Concrete core. The in–fill material inside Steel tubes is required to be of the quality as to increase the ductility, but not the strength of composite columns, many kind of in–fill materials were used to improve ductility of composite columns. Among the various in fill materials, we are using Halloysite Nano Tubes (HNT’s). 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 In this experimental research , the effects of the diameter, length of steel tube, grade of concrete & volume fractions of HNT’s to concrete (0%,0.1%,0.2%,0.3%) on the behavior of Halloysite Nano Tubes(HNT’s) concrete filled steel tube columns under axial compression are being investigated. Also, study being conducted on the effect of Diameter (D), Change in steel tube length (l), and Strength of infill (fCK) and the ultimate load (Pult) & deflection (Δaxial) in HNT’s composite steel hollow tubes under monotonic loading and SEM (scanning electron microscope) images are taken during mixing, before testing and after testing along with the Steel tube –Fracture analysis carried out for the buckled steel tubes using Radiographic Testing.
