2 cards from this section. Quick, good the night before a test.
What is the primary purpose of the Flow Table Test?
Think about why concrete flow is important.
What apparatus is used in the Flow Table Test?
Remember, it involves a special table and mold.
What is the significance of the Flow Table Test in concrete workability?
Think about what aspect of fresh concrete it assesses.
True or False: The Flow Table Test is suitable for testing very low workability concrete.
Consider the type of concrete being assessed.
A concrete mix is tested, and it spreads to 600 mm in both directions after the Flow Table Test. If the original diameter was 400 mm, calculate the flow percentage.
Use the provided formula carefully.
How would you modify the concrete mix if the Flow Table Test indicated poor flowability, say only 350% spread for a self-compacting mix?
Think about what factors affect flowability.
