Pulse velocity measurements on concrete dams
Pulse velocity method, using soniscope is convenient and reliable technique for measuring velocities through path lengths up to 23 m or more; reproducibility of measurements through good quality concrete is within about 2%; deterioration of concrete is indicated by abnormally low velocities; Portland Cement Association has conducted tests on 29 concrete dams; included are gravity, arch, and buttress types; concrete in most of them is of sound quality, but some have shown surficial cracking or deterioration and others have been affected by alkali-aggregate reaction or other undesirable effects.
