Abstract Based on aluminum sulfate, a fluorine-free and alkali-free liquid accelerator (FF-AF-A) was prepared in this
study. The setting time and compressive strength of three cement types with different FF-AF-A dosages were fully
investigated. The compatibility of the FF-AF-A with the superplasticizers were also investigated, and the early
hydration behavior and morphology of the hydration products of reference cement paste with the FF-AF-A were
explored by hydration heat, X-ray diffractometry (XRD), and scanning electron microscopy (SEM). Test results
indicated that adding the FF-AF-A at 8 wt% of the cement weight resulted in 2 min 35 s initial setting time and
