2 cards from this section. Quick, good the night before a test.
What is specific gravity?
Think about how to compare weight with something.
What is the normal specific gravity range for aggregates?
Refer to the values mentioned during the lesson.
What does specific gravity measure?
Consider the definition of specific gravity.
True or False: Bulk specific gravity includes water in the pores of the aggregate.
Reflect on what 'bulk' means.
You have two types of aggregates for a concrete mix: Aggregate A has a specific gravity of 2.5, and Aggregate B has a specific gravity of 3.0. If you need a mix that utilizes both while optimizing mix strength, how would you choose the proportions?
Reflect on how specific gravity relates to strength.
A project requires concrete with a specific gravity close to 2.7. You have aggregates with specific gravities of 2.3, 2.4, 2.6, and 2.9. How would you proceed to create the required concrete mix?
Think about how mixing aggregates impacts the outcome.
