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
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.
2 / 10
What is the maximum allowable difference in readings between the reference and the test temperature measuring devices during verification?
The difference in readings between the reference and the test temperature measuring devices should not exceed 0.5 °C during verification.
3 / 10
At what maximum time interval after obtaining the sample should the temperature of the concrete be measured?
4 / 10
What should be done to the sample container before sampling freshly mixed concrete?
Immediately prior to sampling the freshly mixed concrete, the sample container should be dampened with water.
5 / 10
What is the primary purpose of ASTM C1064?
ASTM C1064 provides a method for measuring the temperature of freshly mixed hydraulic-cement concrete to verify conformance to specified temperature requirements.
6 / 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.
7 / 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.
8 / 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.
9 / 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.
10 / 10
Within how many minutes should the temperature of freshly mixed concrete be measured after obtaining the sample?
The temperature of the freshly mixed concrete should be measured within 5 minutes of obtaining the sample to ensure accurate readings.
