AI Technical Summary
Existing methods for predicting the early-age strength of concrete, such as the maturity method, cannot take into account the influence of moisture conditions, resulting in limited prediction accuracy under complex on-site conditions.
By combining maturity and resistivity, and by monitoring the in-situ temperature and resistivity of concrete, the baseline strength estimate and strength correction value are calculated. The deviation of the maturity model is corrected by the resistivity change rate, thus achieving high-precision early-age strength prediction.
It significantly improves the accuracy of early-age strength prediction for concrete, responds in real time to changes in internal state, reduces errors caused by moisture loss and material differences, and provides reliable support for construction decisions.
