| Summary: | Grade 20 and 30 of young concrete paste with water-cement ratios 0.5 and 0.6 have
been studied using ultrasonic wave. The young concrete paste ages between one day
and 28 days have been tested with an ultrasonic combined method. Relative amplitude
of pressure wave, amplitude A and velocity Vp of the ultrasonic wave parameters have
been measured for the compressive strength of the young concrete. Moisture content
of the young concrete paste was also been studied to determine its effect on the
concrete paste parameters in relation to the compressive strength. The relative
amplitude the pressure wave amplitude A and the pressure wave velocity of the
ultrasonic wave showed clearly that the parameters varied with the change of the
compressive strength. However the effect of moisture on these parameters are also
large and therefore the effect of moisture on the measurement should be taken into
account |
