Cementitiously Stabilized Materials Using Ultrasonic Testing

摘要：

　　The effect of curing time and compaction effect on cementitiously stabilized materials (CSM) was studied using ultrasonic P-wave propagation.In general, the P-wave velocity increased with curing time.The trend between unconfined compression strength (UCS) with dry density or compaction water content was the same as the trend with P-wave velocity measurements.For stabi lized fine-grained soils, there was a peak in P-wave velocity coinciding with the maximum dry den sity.The P-wave velocity and constrained modulus were strongly correlated to the UCS for CSMs.A model for prediction of UCS was proposed.These test results provide insights for use of ultrasonic pulse velocity testing method for the determination of mechanical properties of CSM.
