Given an aggregate with a water absorption rate of 6%, calculate how this would affect the water-cement ratio when using a mix design for concrete. If the specific gravity of the aggregate is 2.5, what considerations must be placed in the design?
💡 Hint: Recall how absorption impacts mixing ratios.
If an engineer has both rounded and angular coarse aggregates, explain how to decide which is more appropriate for a specific concrete application.
💡 Hint: Consider the function of the concrete in the overall structure.
