Show hintHide hint
Consider how we assess structures under load.
Question 5.
Consider a scenario where the Aggregate Impact Value of tested aggregates is found to be too low. Discuss the potential impact on the concrete's performance and suggest alternatives.
Show hintHide hint
Think about how aggregates react under stress over time.
Question 6.
If it is discovered that the aggregates are prone to alkali-silica reactivity after conducting the ASR test, detail the strategies that can be employed in the project to ensure concrete longevity.
