—The economic efficiency of the slip form system
depends on the careful maintenance of the adequate lifting speed
enabling to satisfy the construction quality required on site. This
lifting rate is determined with respect to the extent of setting of
concrete. This study intends to measure the extent of hardening of
concrete placed inside the slip form system using the surface wave.
The wavelet transform is adopted for the analysis of the surface
wave. Numerical analysis is then conducted to determine the
appropriate position of the probe for the measurement of the
surface wave. Moreover, the surface wave velocity is measured
according to the hardening degree of concrete by performing
penetration resistance test, compressive strength test and surface
wave velocity measurement test with respect to the mix
proportions and curing temperature of concrete. This process
enabled us to determine the surface wave velocity necessary for the
rise of the slip form system. The validity of the surface wave
velocity determined in this study as a criterion for the lifting of the
slip form system is finally established by means of a mockup test.
