10 Questions
What was the ratio of cementitious materials in the concrete mixture?
500 lb equally divided between cement and fly ash
What was the purpose of adding a double dosage of chemical retarder?
To minimize slump losses and maintain workability
What was the average slump loss during the 20-minute test?
0.68 in.
What was the temperature range of the concrete during testing?
86 to 93°F (30 to 34°C)
What was the total number of slump tests performed?
270
Why was the precision data applicable to both metal and plastic molds?
Because both metal and plastic molds produced comparable results
What is the definition of 'same materials' in this context?
Freshly mixed concrete from one batch
What is the bias of this test method?
It has no bias
What was the unit of measurement used to develop the precision statement?
Metric units (millimeters)
What is the purpose of the retarder in the concrete mixture?
To slow down the setting process
This quiz is based on the ASTM International standard for concrete slump test, focusing on precision, standard deviation, and acceptable range of results. It covers the data and calculations related to the test. Test your knowledge of concrete workability and plasticity!
