The fresh concrete temperature essentially depends on the temperatures of the raw materials used. By influencing the temperatures of the main concrete constituents cement, aggregates and water, the change in fresh concrete temperature can be estimated.
Our "golden rule" at KTI is:
A 1K (1.8°F) change in fresh concrete temperature results from a...
- ... Change in cement temperature by approx. 10K (18°F).
- ... Change in water temperature by approx. 3.6K (6.5°F).
- ... change of the temperature of the aggregate by approx. 1.6K (2.7°F).
- ... Addition of 7 kg (15.5 lb) of ice.
[Assumption: cement 300kg/m³ (505 lb/yd³), aggregates 1900kg/m³ (3200 lb/yd³), water 170l/m³ (34 US.Gal/yd³)]
