Nanocrystalline nucleus suspension liquid based on industrial solid waste and preparation method thereof

The invention discloses a nanocrystalline nucleus suspension liquid based on industrial solid waste and a preparation method thereof. The preparation method comprises the following steps: treating calcium-silicon industrial solid waste by protonic acid to obtain calcium-silicon industrial solid waste dissolution liquid; dispersing a polycarboxylate superplasticizer into water, and adjusting the pHvalue to 10.5-13.5 to obtain a polycarboxylate superplasticizer dispersion liquid; and slowly dropwise adding the calcium-silicon industrial solid waste dissolution liquid into the polycarboxylate superplasticizer dispersion liquid, and carrying out stirring reaction to obtain a calcium silicate hydrate nanocrystalline nucleus suspension liquid. The calcium and siliceous raw materials used in thepreparation method are from industrial solid waste and are wide in source and low in cost, the preparation process is simple, subsequent processes such as washing, drying and ultrasonic dispersion are not needed, and the prep
