摘要

In order to study the mechanical and deformation characteristics of rubber concrete under repeated loading,50 cycles of high-stress equal amplitude cyclic loading and uniaxial compression tests were carried out on 30 concrete specimens of 5 groups.The change of uniaxial mechanical properties and the deformation during cyclic loading of normal concrete(NC)and rubber concrete(RC)with 5%,10%,15%,and 20%content were analysed.The results show that the peak stress and modulus of elasticity decrease and the peak strain increases with the increase of rubber content.After cyclic loading,the degradation degree of NC peak stress and elastic modulus reached 11.0%and 36.8%respectively.This study can provide a basis for the application of rubber concrete.
