the most important method of regulation used with the lowpercentage al2o3 slag cements in the usa is the whiting process this process includes the use of caustic soda caustic potash sodium chloride ampc added either as aqueous solution or in a dry state at some stage of the process of cement manufacture.

the strength of cements was defined in small samples from cement paste 10 with watercement ratio of 028 the results given in table 3 show that the use of slags in raw materials instead of clay positively affects the activity of clinkers the strength improvement within a 28day interval at full replacement of a clay component with slag made 62.
