Question 5.
Discuss how a lack of control charts might impact the integrity of a concrete project and suggest a strategy to mitigate this risk.
Show hintHide hint
Consider the long-term implications of monitoring strength on your project.
Question 6.
A construction site used volume batching for a concrete mix. As a result, they faced issues with varying concrete quality. Propose a change in their batching process and justify your choice.
