  • 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.

  • How Temperature Affect Grinding Efficiency

    The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1. As can be seen the effect at high

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
