Abstract This study investigated the effect of inorganic salt hardening accelerator (including sodium thiocyanate, sodium sulfate and sodium thiosulfate) on early age hydration of cement by means of in-situ XRD analysis and isothermal calorimetry. Analysis on the quantitative results of hydration samples in each group was also carried out. Results revealed that the three hardening accelerators with a proper dosage range were able to promote the hydration of C₃S, C₃A and C₄AF and accelerate the hydration heat evolution in different degrees. Consequently, the degree of early age hydration of cement was improved. The conclusion drawn from quantitative results of in-situ hydration samples was in consistent with the variation law of isothermal calorimetry curve, indicating the effectiveness and reliability of in-situ XRD in investigating the early age hydration of cement.

Key words： in-situ XRD hardening accelerator cement hydration
