RISRetarding Mechanism of Nano-Zn-Fe Hydrotalcites for Sulfoaluminate Cement-Based Grouting Materials
Publisher: American Society of Civil Engineers
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 ...
Synthesis of Shrinkage-Reducing Admixture with Different Branch Chain Structures and Its Effect on the Drying Shrinkage of Cement-Based Materials
Publisher: American Society of Civil Engineers
Abstract: AbstractShrinkage-reducing admixtures (SRAs) can effectively mitigate the drying shrinkage
of cement-based materials, but the influence of SRA structures with varying configurations
on drying shrinkage remains unclear. ...
Effect of Magnesium Fluosilicate on the Properties of Sulfoaluminate Cement–Based Grouting Materials
Publisher: American Society of Civil Engineers
Abstract: AbstractSulfoaluminate cement–based grouting materials (SAGMs) are frequently employed in
projects concerning reinforcement and repair. Retarders are often added to SAGMs to
improve their workability by delaying the hydration ...
