Additive for improving early strength of cement based material as well as preparation method and application of additive
The invention provides an additive for improving early strength of a cement based material. The additive is prepared by the reaction of an ionic copolymer and silane, wherein the ionic copolymer is prepared by the reaction of a monomer A, a monomer B, a monomer C and a monomer D. The invention further provides a preparation method of the additive for improving early strength of the cement based material and application of the additive in improvement of the early strength of the cement based material. The additive is simple in preparation process, convenient to use, low in cost and relatively high in water reduction rate, accelerates the hydration of the cement in the early stage, improves the early strength of the cement based material, particularly shows an obvious effect on improving the early strength of the cement based material at a low temperature environment, is relatively high in adaptability to the raw materials, has a good super early strength improving effect for different cement, and does not have any adverse effect on the future strength and durability.
