Method for preparing novel polycarboxylic acid nanocrystal nucleus type early strength functional powder

The invention provides a method for preparing novel polycarboxylic acid nano crystal nucleus type early strength functional powder, and relates to the field of nano functional powder. The novel polycarboxylic acid nanocrystal nucleus type early strength functional powder is disclosed. By introducing a calcium source and a silicon source step by step, the prepared nanocrystal nucleus can be uniformly dispersed into the water reducer, so that the calcium water-reducing complexing agent can be better dispersed into a concrete system, and the problem of dispersity of the nanocrystal nucleus is effectively solved; the water-reducing agent provides crystal nucleus growth points for cement hydration reaction, reduces the activation energy mode for forming hydration product C-S-H gel, has excellent water-reducing effect, accelerates concrete coagulation, and improves early strength. And the prepared water-reducing complexing agent does not contain components which damage the long-term strength of concrete and acceler
