4 cards from this section. Quick, good the night before a test.
What is trial batching?
Think about how we confirm if our concrete works before large production.
Name one test done during trial batching.
It measures the workability of concrete.
What is the primary purpose of trial batching?
Think about the process used before concrete goes into production.
True or False: A slump test is not necessary for trial batching.
Remember what is assessed for placement and compaction.
You have conducted a trial batch that resulted in a slump of 20 mm, but the target was 50 mm. Outline the steps you would take to adjust the mix.
Think about what directly affects workability.
After trial batching, your compressive strength results show only 18 MPa compared to a target of 25 MPa. Discuss potential implications for the project.
Identify factors affecting strength and the impacts on project execution.
