Abstract

The mechanical property and wave velocity of fine sandstone after different high temperature such as 25 400 600 800 and 1000 , be test studied by the servo-controlled testing machine RMT-150B and ultrasonic nondestructive testing instrument TUA2000A. The test results show that: (1) the sensitivity of stage from 400 to 800 is remarkable to stage from 25 to 400 and from 800 to 1000 on the wave velocity and quality. (2) the uniaxial compressive strength is increasing in early stage and reducing in later stage according to the temperature, the turning point is 800 ,and the quadratic polynomial with the conversion between the positive and negative on temperature accurately reflects this change. (3) elastic module is also increasing in early stage and reducing in later stage according to the temperature, and it is the maximum when temperature reaches 400 , the minimum when temperature 1000 is only 45% of initial value.
