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
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.
2 / 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.
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 minimum period that the thermometer should be left in the concrete to ensure a stable reading?
5 / 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.
6 / 10
What is the minimum required size of the concrete sample for temperature measurement according to ASTM C1064/C1064M?
7 / 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.
8 / 10
At what maximum time interval after obtaining the sample should the temperature of the concrete be measured?
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 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.
