水泥在水化过程中生成的钙离子与土颗粒表面的钠离子进行离子交换作用,生成稳定的钙离子,从而进一步提高土体的强度,达到提高其复合地基承载力的目的。
The calcium ions generated in the cement hydration process ion exchange with the sodium ions on the surface of the soil particles to generate stable calcium ions to further enhance the strength of the soil so as to achieve the purpose of increasing the bearing capacity of the composite foundation.
