In this paper, cement and dechlorinated Polyaluminum Chloride Residue (PACR) have been used to prepare a net slurry mortar specimens.Two hydration activity indicators quantitatively analyze the PACR activity.In particular, effect of content on compressive strength has assessed by means tests.Moreover, X-ray diffraction (XRD) scanning electron microscopy (SEM) employed observe microstructure considered products.The following results obtained.The 28th day index is 75%, therefore it meets criterion for use active admixture.The increase in tends reduce specimens, however, beneficial its later growth.When not greater than 10%, remains unchanged, otherwise, decreases.The does form new crystalline phase slurry, until age day.The inclusion mainly deteriorates early but promotes production products after 7th day.
