Using Shear Wave Velocity to Monitor the Curing Process of High Performance Flowable Concrete

Shear wave velocity measurement of geomaterials using bender element has been used widely in geotechnical engineering during the last decades. The shear wave velocity, or the stiffness of a freshly casted concrete will also change significantly from close to zero to 1300- 2000 mjs. However, monitoring of the lateral pressure, instead of S-wave velocity, was currently adopted as the standard method. The first objective of this proposal is to use bender element as a new monitoring tool to monitor the curing process of a concrete. The second objective of this proposal is to use S-wave velocity as a tool to predict the strength of the early (1 or 3 days) strength of a freshly-casted concrete using correlation between these two quantities.
