· Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.
Cement samples from each grind were tested for setting time on at least one of the following penetrometers: the Vicat Needle; the Gilmore Needle; and the Maruto Testing Machine. Roan Industry's RII® 77 grinding aid was used as the standard. The results of the set time tests are shown in Table II. TABLE II.
