What is the temperature range (Fahrenheit) at which cement ...The Basic Idea Behind Proper Curing Is To Allow This Reaction To Continue As Long As Practical By Maintaining A Suitable Curing Temperature, Usually 50°F To 90°F, And By Keeping The Concrete Wet. If The Temperature Of The Concrete Drops Below 50°F, Hydration Begins To Slow, And If The Water In The Mix Freezes, The Concrete Will Be Ruined.
Thermal Expansion and Contraction - Penn State EngineeringConcrete expands slightly as temperature rises and contracts as temperature falls. Temperature changes may be caused by environmental conditions or by cement hydration (the exothermic chemical process in which the cement reacts with the water in a mixture of concrete to create the calcium silicate hydrate binder and other compounds).
Cement kiln - WikipediaAlite is the characteristic constituent of Portland cement. Typically, a peak temperature of 1400–1450 °C is required to complete the reaction. The partial melting causes the material to aggregate into lumps or nodules, typically of diameter 1–10 mm. This is called clinker.
