Consolidation Behavior and Compression Prediction Model of Coastal Cement Soil Modified by Nanoclay

Coastal cement soil modified by nanoclay (NCS) has particular research significance as a modification approach to improve the high compressibility of coastal (CCS). At curing ages 7 days and 28 days, consolidation SEM tests were performed on 6 groups NCS samples with content between 0% 10% CCS 10 20%, compression prediction model was established based test results. Test results show that (1) there is linear interval for improvement effect increment samples. In this test, in 12% 18%. 18% preferred. (2) The sample better 4% 8%, but poor 2%. pressure 100 kPa 800 kPa, (3) Adhesion 4%, filling 8%. (4) cosine-power function-exponential established, measured data are fitted, amount established.
