Effect of Early Strength Agent on Early Strength of Silt-solidified Soil

As a commonly used admixture, early strength agent can effectively accelerate the early solidification process of silt-solidified soil.This paper takes the high water content mudflat of Xuwei, Lianyungang, Jiangsu Province as the research object to study the unconfined compressive resistance of the early solidified soil when the solidification agent is mixed with two early strength agents of calcium formate and sodium sulfateThe influence of intensity.The research results show that: (1) when the two early strength agents are mixed alone, they can play an obvious early strength effect on the silt solidified soil, and the early strength effect of calcium formate is better than sodium sulfate;(2) the two early strength agentsWhen the compound is added, the synergy between the two can be stimulated to further accelerate the early solidification process of the sludge solidified soil. When the calcium formate content is 2% and the sodium sulfate content is 1%, the early strength effect is the best.
