Research on a New Technology for Water-resistant Self-healing Soil Solidification |
| |
Abstract: | Water-resistant self-healing materials were prepared based on polymer technology. By adding active self-healing catalysts, we can repair microcracks inside the structure. A new water-resistant self-healing soil curing technology was carried out. The material properties of water-resistant self-healing stabilized soils were studied in terms of water resistance, self-healing properties and fatigue properties, respectively. The study showed that the water stability of water-resistant self-healing stabilized soil was significantly better than that of cement-lime soil. The curing agent has a significant effect on the strength recovery of the stabilized soil material. The addition of water-resistant self-healing materials improved the fatigue performance of the stabilized soil. |
