MANUFACTURING PROCESS FOR OBTAINING HIGH-STRENGTH RAPID-HARDENING CEMENT

VERFAHREN ZUR HERSTELLUNG VON SCHNELL ERHAERTENDEN ZEMENTEN MIT HOHER FESTIGKEIT

In order to improve the hydraulic characteristics of cement and to produce rapid-hardening cement, organizations in the USSR carried out investigations which showed that the clinker's baking conditions had the greatest influence on the hydraulic properties of cement. The composition and fineness of raw meal, the cooling of the clinker and the fineness of the cement are other parameters affecting the hydraulic properties. If the raw material available has A silicate ingredient containing ferrous oxide, rapid baking of the clinker in a short oven with a short flame is recommended. In a long oven with an extension clinkerization zone, good hydraulic quality clinker is obtained only if the alkali content exceeds 0,7%. Tests 700 and 850 kp/sq.cm. (TRRL)
