2 cards from this section. Quick, good the night before a test.
What is the target slump range for mass concrete?
Think about the type of structure being worked on.
Why is recording test results important?
Consider the implications of having no records.
What is the target slump for reinforced concrete?
Remember the categories of concrete and their respective ranges.
Slump tests should be conducted for each batch of concrete.
Consider the importance of consistency in construction.
A project requires pumped concrete with a target slump range of 100-150 mm. A batch measures 95 mm. Discuss the practical steps to remedy this situation.
What adjustments can improve the workability without compromising strength?
If a frequent slump test results show variations exceeding ±25 mm, what implications does this have, and how could these be resolved?
Consider what factors contribute to workability issues.
