This test method covers the determination of temperature of freshly mixed hydraulic-cement concrete.
1 / 10
What is the minimum period that the thermometer should be left in the concrete to ensure a stable reading?
2 / 10
What is the minimum immersion depth for the temperature measuring device in the concrete?
The end of the temperature sensing portion of the device must be submerged a minimum of 75 mm into the freshly mixed concrete to ensure an accurate measurement.
3 / 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.
4 / 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.
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 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.
7 / 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?
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
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.
10 / 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.
