Test Name: Temperature of Freshly Mixed Concrete
Standard: ASTM C1064/C1064M-23 — Standard Test Method for Temperature of Freshly Mixed Hydraulic-Cement Concrete.

Purpose: To measure the temperature of fresh concrete at the time of testing and verify compliance with the project-specified temperature requirement.

Typical field procedure:

Obtain a representative sample of fresh concrete.
Insert the calibrated thermometer/probe into the concrete.
Ensure the probe is surrounded by concrete and not touching the container.
Allow the reading to stabilize, typically 2–5 minutes.
Record the temperature in °C.

For your photo: the thermometer reading is approximately 30.4°C.

Test Item Result
Concrete Temperature 30.4°C
Test Method ASTM C1064/C1064M-23
Unit °C
Equipment Digital concrete thermometer
Acceptance As per project specification

Important: ASTM C1064 is the measurement method; it does not itself establish a universal maximum concrete temperature. The acceptance limit should come from your project specification/approved mix requirements.
