| Abstract: | An experimental system of real-time laser holographic interferometry under static load has been set up by use of He-Ne laser.The system is applied to the dynamic observation on the whole process of real-time laser holographic interferometry experiment on different concrete specimen under uniaxial compression respectively.At the same time,the strain concrete values of are measured.Estimation of concrete life time is obtained by using of damage mechanics,then giving a experiment method in order to estimate concrete work lifetime. |

| Keywords: | concrete strain-stress work lifetime |
