| 英文摘要 | Real-time monitoring of cementitious material strength development in construction is of great importance for safety and stability of engineering structures. In this paper, a new method for early-age strength prediction of mortar and concrete based on classical elastic wave theory is proposed, combining embedded smart piezoelectric module (SPM) and wave propagation (WP) technique. Two Wave Modulus of Elasticity (WMoE) are derived from wave velocities as the robust indicator to monitor the curing process for mortar and concrete, respectively. Further, series experiments were conducted to determine the optimal excitation wave frequency and waveform. The optimal excitation signals could be represented by a Hanning-windowed 5-peak sine wave with the frequency bandwidth of 100 kHz to 120 kHz. And the WMoE measured by embedded SPMs was verified by surfacepatched SPMs. Finally, the early-age strength prediction models for mortar and concrete are proposed based on the WMoE and actual compressive strength of specimens. The strength prediction model can accurately evaluate the curing process as well as predict strength development of cementitious materials. These results reveal that the proposed method could offer several advantages of reliability, quantitative precision, robustness, and real-time capability for monitoring and assessing the early-age strength development of cementitious materials. |
