| Summary: | The effects of aggregate-cement and water-cement ratios on the relationship between
ultrasonic pulse velocities and the cube compressive strength of concrete under
continues wet curing and wet curing for specilic periods were studied. The
relationship of the velocity with the compressive strength almost unaffected by the
aggregate-cement ratios between 4.8 and 6.8, but the variation of water-cement ratio
between 0.45 and 0.67 has some effect. The differences become more pronounced in
the wet cured samples which have been exposed to the laboratory conditions. The
ultrasonic velocities of similar samples and cured in similar manner but were tested at
different ages follow the same velocity-strength relationship |
