Cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements. The aluminium oxide and iron oxide are present as a flux and contribute little to the strength. For special cements, such ...

White Clinker – White clinker is characterized by its purity and bright, light color. Manufacturers create white clinker by using raw materials with a low iron and manganese content. This is the primary material in white cement. High Alumina Clinker – This clinker has a higher level of alumina than other clinker types. This is essential in ...

Cement is a hydraulic binder; it consists of a finely ground inorganic material which forms a paste when mixed with water, is able to set and harden because of numerous exothermic hydration reactions (and processes), and is thus capable of binding fragments of solid matter to form a compact whole solid [1,2,3].After hardening, cement retains its …

Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone, these volatile phases are in liquid form and a proportion volatilizes, the remainder passing out of the kiln in the clinker as inclusions within the ...

It was determined that there are no significant differences between the chemical and mineralogical composition of G70 cement and its clinker. Granite cutting waste (GCW) (Sa = 913 m2 kg-1, q = 2.927 g-1 cm3) is a by-product of granite production in the plant of JSC ''Granitas.'' X-ray fluorescence (XRF) analysis showed that GCW mainly ...

Other additives may be used instead of gypsum, depending on the cement. Clinker can keep for months in dry conditions. If it gets rained on, you'll have a singularly useless job-lot of hardened concrete-type material on your hands. When water is added, clinker initially reacts by turning into a gritty puddle, more commonly known as cement paste.
