【 摘 要 】

Solid polycarboxylate superplasticizer can not only solve the problems caused by water reducing agent in storage and transportation, but also meet the needs of some special projects. We can choose to use the mineral slag, which is larger than surface area and has stronger adsorption, as adsorbent to absorb liquid polycarboxylate superplasticizer and absorb its moisture, and then makes solid polycarboxylate superplasticizer after drying. It determines the solid-liquid ratio to prepare the solid polycarboxylate superplasticizer to be 3:1. The temperature change within 100°C will not cause changes in the functional group and structure of the water reducing agent molecule. The application of the solid polycarboxylate superplasticizer was basically unchanged compared with its liquid water reducing agent.
