Challenge Problems
Push your limits with challenges.
Question 1
You perform a sieve analysis, finding that 30%, 20%, and 25% of aggregate are retained on different sieves. How would you calculate FM and what could be the implication of that FM for concrete workability?
💡 Hint: Sum all retained percentages carefully.
Question 2
If the requirements for a high-strength concrete mix set the FM limit at 2.5, but your selection yields an FM of 3.2. What adjustments could you consider?
💡 Hint: Focus on sourcing aggregates with finer qualities.
