摘要 |
FIELD: inspection of strength of concrete and ferroconcrete structures. ^ SUBSTANCE: strength of concrete in concrete and ferroconcrete structures includes measurement of speed of ultrasound in samples-cubes and material of structures, mechanical testing of samples-cubes, building of calibration dependence of "speed of ultrasound - strength of concrete" from the results of measurements and testing of samples-cubes and determining of strength of concrete from the results of ultrasonic measurements and preliminary built calibration dependence. Average humidity of tested samples-cubes of concrete is determined on the base of different sets of samples-cubes of concrete. Average speed of propagation of ultrasound in samples-cubes and average strength of concrete cubes-samples are determined the same manner. Value of strength s set by mathematical relations. ^ EFFECT: improved precision; improved reliability of determination of strength of humid concrete. ^ 2 dwg |
