The hydration of cement is highly related with the mixing condition. The influence of mixing order to firstly add water or cement and mixing mass on the properties cement paste was investigated. XRD and Rietveld quantification was applied to study the hydration process and NMR is utilized to study the pore structure evolution. The results suggest the change in mixing condition does not intensively affect the hydration degree but affect the pore structure. Changing mixing procedures especially the mixing order exert a long-lasting influence the water distribution in interhydrate and gel pores.
