Retarding Mechanism of Nano-Zn-Fe Hydrotalcites for Sulfoaluminate Cement-Based Grouting Materials

Abstract

AbstractA retarder is often required to maintain the workability of sulfoaluminate cement-based grouting materials (SCGMs). Carbohydrates are widely used as cement retarders, but a high carbohydrate content can degrade the late-stage performance of ...
