Early Age Concrete

A modified one-sided Rayleigh wave (R-wave) velocity measurement technique is applied to monitor the strength gain of early-age concrete. A series of experiments were performed on early-age concrete specimens with various curing conditions. The results show that the R-wave velocity and strength gain has a strong relationship and that the R-wave velocity can be effectively used to monitor the strength development of the early-age concrete.

Early Age Concrete

Monitoring the concrete early-age strength gain at any arbitrary time from a few minutes to a few hours after mixing is crucial for operations such as removal of frameworks, prestress, or cracking control. This paper presents the development and evaluation of a potential active wireless USB sensing tool that consists of a miniaturized electromechanical impedance measuring chip and a reusable piezoelectric transducer appropriately installed in a Teflon-based enclosure to monitor the concrete strength development at early ages and initial hydration states. In this study, the changes of the measured electromechanical impedance signatures as obtained by using the proposed sensing system during the whole early-age concrete hydration process are experimentally investigated. It is found that the proposed electromechanical impedance (EMI) sensing system associated with a properly defined statistical index which evaluates the rate of concrete strength development is very sensitive to the strength gain of concrete structures from their earliest stages.
