BAI Hao
Abstract：In order to study the energy evolution characteristics of carbon nanotube-polyvinyl alcohol concrete under uniaxial compression,different contents of carbon nanotube-polyvinyl alcohol concrete were designed and uniaxial compression tests were carried out.The results show that the appropriate amount of carbon nanotubes is beneficial to improve the uniaxial compressive strength of concrete,but the strength will decrease after the excessive amount of carbon nanotubes,when the content of carbon nanotubes is 0.5％,the uniaxial compressive strength is increased by 20.04％;The energy evolution of ordinary concrete and carbon nanotube-polyvinyl alcohol concrete undergoes four stages;With the increase of carbon nanotube content,the total strain energy and elastic strain energy at the peak stress point increase first and then decrease;The evolution of energy density before peak stress satisfies the exponential function relationship.
