ASTM C-1064 (Temperature of Freshly Mixed Concrete)

ASTM C-1064 is a standard test method used to measure the temperature of freshly mixed concrete. It ensures that the concrete’s temperature is within specified limits to achieve optimal setting and strength properties. Proper temperature control is vital because high temperatures can cause rapid setting and reduce durability, while low temperatures may delay setting and affect strength development. The test involves inserting a calibrated thermometer or temperature probe into the freshly mixed concrete to accurately record its temperature. This standard helps contractors maintain quality and consistency during concrete placement, ensuring the final structure meets design specifications and performs reliably over time.
