C1064/C1064M – 17—Temperature of Freshly Mixed Hydraulic-Cement Concrete
This test method covers the determination of temperature of freshly mixed hydraulic-cement concrete.
1 / 10
At what maximum time interval after obtaining the sample should the temperature of the concrete be measured?
2 / 10
What should be done after placing the temperature measuring device in the freshly mixed concrete?
After positioning the temperature measuring device, gently press the concrete around the device at the surface to prevent ambient air temperature from affecting the reading.
3 / 10
What type of container is required for measuring the temperature of freshly mixed concrete?
The container must be large enough to ensure there is at least 75 mm of concrete in all directions around the sensor to accurately measure the temperature.
4 / 10
What is the significance of the number following the designation C1064/C1064M in the standard?
The number following the designation indicates the year of the last revision of the standard.
5 / 10
How often should the accuracy of the temperature measuring device be verified?
The accuracy of each temperature measuring device used for determining the temperature of freshly mixed concrete should be verified at least annually.
6 / 10
Which ASTM standard is referenced for the definition of terms used in ASTM C1064?
ASTM C125 is the standard that provides terminology relating to concrete and concrete aggregates used in ASTM C1064.
7 / 10
What type of bath is used for verifying the accuracy of temperature measuring devices?
Verification of the accuracy of the temperature measuring devices may be made in oil or other suitable bath liquids having uniform density.
8 / 10
Which committee is responsible for the ASTM C1064 standard?
ASTM Committee C09 on Concrete and Concrete Aggregates is directly responsible for the ASTM C1064 standard.
9 / 10
How long should the temperature measuring device remain in the concrete to obtain a reading?
The device should remain in the concrete for at least 2 minutes but not more than 5 minutes before reading the temperature.
10 / 10
What is the minimum period that the thermometer should be left in the concrete to ensure a stable reading?
