Characteristics and Application Potentials of Ground Improvement with Semi-Rigid Inclusions Based on an Innovative Composite of Polymers and Gravel-Video

Video Transcription

Video Summary

The presentation introduces a semirigid ground-improvement composite made from polymer and gravel, developed with Keller and TPH. Image analysis measures polymer content and distribution, supporting quality control in laboratory samples and field drill cores. Rheometer tests show that one polymer gains initial strength sooner than the other; raising the ground temperature from 10°C to 20°C approximately doubles the reaction rate. Numerical simulations compare composite columns with stone and concrete columns: stone columns transfer loads through surrounding soil, while composite columns act mainly as vertical supports.
