Solidification Effect and Mechanism of Marine Muck Treated with Ionic Soil Stabilizer and Cement
In this study, an environmentally friendly ionic soil stabilizer (ISS) was adopted with combination of Portland cement to stabilize a marine muck. The macro and micro tests results demonstrated that the ISS was an effective stabilizer to improve the strength of marine muck when it was used combined...
