    Heat generated in the grinding process causes gypsum (CaSO4.2H2O) to lose water, forming bassanite (CaSO4.0.2-0.7H2O) or γ-anhydrite (CaSO4.~0.05H2O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminatehydration. If more than this amount forms, crystallization of gypsum on their re-hydration causes "false set" a sudden thickening of the cement mix a few minutes after mixing, which thins out on re-mixing.

Cement Clinker Quality Control During Clinker Production

4. Calcination temperature. During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.

Why Concrete Temperature Testing Is Important During

23/3/2018· Concrete Temperature Control During Mixing and Curing. In cold weather, the temperature of the concrete can be controlled by providing appropriate curing conditions to maintain insulation and strength gain, such as the use of heating systems. High curing temperatures can also be controlled when mass pouring with cooling pipes. The temperature when the concrete is placed can

Methods of Limiting Temperature of Concrete

The maximum allowable concrete temperature rise can not be fixed to the exact value. It depends on the type of concrete and its composition. However, there are general norms for limiting the temperature of the concrete. American Concrete Institute also provide some guideline on the temperature variations. According to the general norms in the construction industry, it is fixed to 70 Celsius

As an example, to reduce the maximum concrete temperature by approximately 10 F (6 C), the concrete temperature at the time of placement should generally be reduced by 10 F (6 C). Methods to precool concrete include shading and sprinkling of aggregate piles (as appropriate), use of chilled mix water, and replacement of mix water by ice. Efforts to cool aggregates have the most pronounced
