Abstract
We conducted a survey on the actual conditions of material temperatures at ready-mixed concrete plants in 4 areas (Fukuoka, Osaka, Aichi, Tokyo) in hot weather in 2018. Cement is 45-55°C, groundwater is 20-25°C, and other materials are slightly lower than 30°C. The amount of temperature increase of the material temperature with respect to the outside temperature of 1 °C is 0.38 to 0.4 °C for aggregate and 0.25 to 0.32 °C for mixed water other than groundwater. Based on the current situation of 4 areas, the need for further temperature control measures for the materials used was shown.
