YOUNG’S MODULUS OF CAEBON NANOTUBESS REINFORCED CONCRETE USING REPRESENTATIVE ELEMENTARY VOLUME METHODOLOGY & ANSYS

Abstract

The catastrophic failures of concrete structures occur everywhere due to natural calamities such as floods, earthquakes, Tsunamis, cyclones and volcanoes. The man-made disasters due to war and bombing leads to huge amount of property loss and lives. To prevent the occupants and the property, the strong column weak beam theory is adopted in seismic prone areas. However the failures or cracks in structures could never be eliminated. With advent of nanotechnology & its applications in concrete, this research investigation focuses on developing a newer material by reinforcing concrete with CNT fibres and macroscopic CNT bars. Nano technology promises crack free materials and structures that could stand for a millennia. So far the CNTs have been known in the form of powder and recent technologies have projected the possibilities of using CNTs as cables for suspension cable bridges with reduced cross sectional area and the Japanese had proposed space elevators using CNT technology
