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
According to ASTM C1064, what should be done if the temperature measuring device fails verification?
If the temperature measuring device fails verification, it may be adjusted and then reverified to check if it then meets the required accuracy.
2 / 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.
3 / 10
According to ASTM C1064/C1064M, the temperature measuring device must be capable of accurately measuring the temperature of fresh concrete to within what range?
4 / 10
How should the thermometer be inserted into the concrete sample to ensure an accurate temperature reading?
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
What is the reported accuracy of the reference temperature measuring device?
The reference temperature measuring device must be readable and accurate to ±0.2 °C at the verification points.
7 / 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.
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
At what maximum time interval after obtaining the sample should the temperature of the concrete be measured?
10 / 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.
