Resonant Frequency Ultrasonic P-Waves for Evaluating Uniaxial Compressive Strength of the Stabilized Slag–Cement Sediments

Abstract Marine sediments can be stabilized by ultra high-strength binders: cement, Cement Kiln Dust (CKD) and slag. The properties of the soil indicate potential to their reuse. This study investigated performance unconfined compressive strength (UCS) in marine binder (cement, CKD, slag), tested ultrasonic P-waves. Materials include 194 specimens collected from port Gothenborg. experiment was performed Swedish Geotechnical Institute (SGI). UCS different ratio binders slag) resonance frequencies elastic significant increase (>1500 kPa) recorded for highest values CKD low correlation profiles water/high (L W /H B ) cement/slag (40/60%) were controlled curing time. slag–cement–CKD simplex tests demonstrated samples with low/high water content various cement (kg/m 3 ). time play a critical role followed mechanical intensity stress. exceed 1000 m/s results shown high accuracy (97%) non-contacting approach testing sediments. Seismic methods applied test sediments, also in-situ via seismic CPT, surface or cross hole testing.
