concrete workability mill temperature

Effect of temperature of fresh concrete on workability …

this is because the high temperature increases the heat of hydration process of cement due to which concrete workability decreases. ideal temperature during concrete pouring is between 24 to 32 c but 36 C is the maximum temperature allowed in hot weather concrete. higher temperature can lead to cracks and decrease the durability.
