Rising Experiment of Slip Form System Using Surface Wave Velocity

Hee Seok Kim, Young Jin Kim, Won Jong Chin, and Hyejin Yoon

Abstract—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.

Index Terms—Slip form system, setting of concrete, surface wave velocity, wavelet transform.
