| Abstract: | In order to simulate work environment of high dam concrete and effects on the mechanical properties of concrete due to high seepage pore water pressure,standard concrete samples are immersed into a high water pressure container and high hydraulic gradient is produced in testing samples.The concrete mechanics and physical properties studied in the paper are included strength,young's modulus,water content and wave velocity.The effects due to different water pressure in the container(concrete pore water pressu... |
