AI Technical Summary
In existing technologies, the early strength of high-moisture-content sludge is insufficient, resulting in slow construction progress and high costs. Ordinary silicate cement hydrates slowly and has low early strength. Increasing the dosage of cement-based curing agent leads to problems such as high cost and excessive soil pH.
A polymer-modified curing agent is used to form a mixture by mixing silicate cement, sulfoaluminate cement, mineral powder, desulfurized gypsum, quicklime, redispersible latex powder, and other components. The curing agent is then stirred and pumped into the silt layer using a mixing head and pumping pipe to form solidified soil, stimulate early and late strength, and control the pH value.
It achieves early strength enhancement of high water content sludge, meets engineering requirements, allows for rapid large-scale mechanical construction, has good later strength and solidification effect, reduces costs, and avoids the problem of excessive pH value.
