effect of cement mill temperature on cement properties

WHAT ARE THE EFFECTS OF HOT COLD WEATHER ON CONCRETE
Jan 11 2015 · Effects of Hot Weather on Concrete Any operation of concreting done at atmospheric temperature above 400C may be put under hot weather concreting. The effect of hot weather may be as follows Accelerated setting A higher temperature of fresh concrete results in a more rapid hydration and leads to reduced workability/ accelerated setting.

Curing Effects on High-Strength Concrete Properties
This study was conducted to investigate the impact of hot and dry environments under different curing conditions on the properties of high-strength concrete. The concrete samples were prepared at a room temperature of 20°C and cured under different curing conditions. Some specimens underwent standard curing from 24 h after casting until the day of testing.

Effect of High Temperatures on Concrete Concrete
High temperatures also affect the compressive strength of concrete. Above 212º 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.

Effect of nanosilica on the mechanical properties of oil
The effects of nanosilica (NS) on the properties of cement slurries were studied at low temperatures. It was found that the early strength of cement slurries was significantly enhanced with the addition of NS. Furthermore sedimentary stability and the ability to control fluid loss were improved at low temperatures.
