水泥-矿渣-分散剂协同固化淤泥黏土性能研究
Performance of cement-slag-dispersant synergistically solidified silty clay
摘要
Abstract
Taking marine silty clay as the research object,experimental studies were conducted on the flowability,setting time,and compressive strength of fluidized solidified soil.The influence mechanism of different organic polymer dispersant dosages,solidifying agent dosages,and cement slag ratios in solidifying agents on the physical properties of solidified soil was revealed,and a normalization method was used to establish an engineering mix design model.The research results indicate that organic polymeric dispersants can achieve the plastic flow transition of viscous solidified soil,and their dosage increases with the increase of the dosage of solidifying agent and the mass ratio of cement slag.The setting time of fluidized solidified soil decreases with the increase of the dosage of solidifying agent and the mass ratio of cement slag.When the dosage of solidifying agent is 20%and the mass ratio of cement slag is 6∶4,its compressive strength reaches its maximum.Organic polymeric dispersants delay the setting time and reduce the strength of solidified soil by altering the growth and distribution of the solid liquid gas three-phase space inside the solidified soil.The research results can provide theoretical support for the construction technology of viscous flow solidification.关键词
