Liquid cement modifier and application thereof

The invention discloses a liquid cement modifier and application thereof, and belongs to the technical field of cement process admixtures. The liquid cement modifier comprises the following raw material components in percentage by mass: 1-8% of a lattice distortion induced modifier, 3-8% of a precipitation accelerator, 1-3% of a complexing agent, 10-40% of an early strength agent, 0.5-4% of a retarder and the balance of water. When the liquid cement modifier is applied to a cement processing technology, the mixing amount of the liquid cement modifier in cement is 0.3-0.8% of the mass of the cement. The liquid cement modifier can meet the requirements of different types of cement, can improve the 3-day strength and 28-day strength of the cement at the same time according to the characteristics of the cement, effectively reduces the clinker proportion, and saves the cost. 本发明公开了一种液体水泥改良剂及其应用，属于水泥工艺外加剂技术领域。所述液体水泥改良剂按质量百分比计，原料包括以下组分：晶格畸变诱导改性剂1～8％、沉淀加速剂3～8％、络合剂1～3％、早强剂10～40％、缓凝剂0.5～4％，余量为水。所述液体水泥改良剂应用于水泥加工工艺时在水泥中的
