HOT WEATHER CONCRETING
To meet the required concrete temperature of fresh concrete during ‘Hot Weather Concreting’, as per ACI 305-5.13.The following support facilities are adopted & considered to reduce the temperature of fresh concrete. The temperature of fresh mixed concrete should not exceed 32 degrees and we shall take all necessary precaution to ensure that this limit is not exceeded. Concrete with a temperature less than 32 degrees will be produced by combinations of the following methods. The support facilities (erected on the plant) are as follows:
- Shading aggregates.
- Aggregate Washing plant.
- Moistening of aggregate with portable water.
- Use of cement with a low temperature i.e. less than 77º C.
- Water Chiller Plant
- Ice Plant
- Shading of mixing area.
- Use of white paints on cement silos, Micro-silica silos.
- Use of thermocol insulation in water pipeline & water storage tanks.
As part of these precautions, extra efforts have been made to keep the concrete temperature as low as possible within considerable limits. For maximum effectiveness, the ice should not be allowed to melt before it is placed in the central mixer and in contact with other raw materials but it should melt completely prior to the completion of mixing of the concrete. All procedures mentioned above are implemented.
