CEMENT ADDITIVES DIVISIONCement additives ScienceDirect,2015-1-1 · Abstract. This chapter deals with special chemicals that can be used as cement additives. There are two basic kinds of activities in cementing, namely, primary and secondary cementing. Primary cementing fixes the steel casing to the surrounding formation. Secondary cementing is used for filling formations, sealing, or water shutoff.
