Effect Of Temperature On Cement Grinding

Dec 01, 1999 High temperatures also affect the compressive strength of concrete. Above 212 F, the cement paste begins to dehydrate (loses chemically combined water of hydration), which gradually weakens the paste and paste-aggregate bond. The temperature that concrete has reached often can be determined by observing color changes in the aggregate

    The effects of grinding temperature on the grindability and quality of cement were discussed mainly from the standpoint of the action of gypsum. A mixture of normal portland cement clinker and natural gypsum (SO 3 =1.7 in the resulting cement) was ground in the test mill at 25-200 C for 20-100 min. which is provided with a heating device
