Abstract

Early age cracking of structures often leads to aesthetic problems and service life
reduction. Among the parameters involved in the stress build-up that causes this cracking process,
the stiffness evolution is of major importance for models and numerical computations. This paper
reports the use of six different techniques aimed for stiffness evolution assessment, applied on the
same concrete mix, in a round robin experimental test within three laboratories. The observations
are compared after having expressed the results at the same maturity. Some of the reported
techniques provide original means for Young's modulus monitoring of concrete at early age both
for industrial and research applications. Two sets of results emerge. Ultrasonic measurements
provide values of Young's modulus much higher than the values provided by the static or quasi
static tests at the time of the concrete setting. This difference decreases as the concrete hardens.
