Show hintHide hint
Think about how rough surfaces work.
Question 5.
Given a set of aggregates with a size distribution and a known bulk density, calculate the required volume of paste needed to fill voids in a concrete mix.
Show hintHide hint
Consider how void spaces determine paste requirements.
Question 6.
Explain what adjustments you would make to a mix if the bulk density was found to be lower than expected.
Show hintHide hint
Think about how density impacts material requirements.
