What is the target flexural strength calculated for M40 concrete?
💡 Hint: Remember the formula for calculating target strength.
True or False: A lower water-cement ratio improves the workability of concrete.
💡 Hint: Consider the balance required for both workability and strength.

Challenge Problems
Push your limits with advanced challenges
A new specification requires increasing the target flexural strength to 5.5 MPa due to higher environmental demands. How would you adjust the water-cement ratio to achieve this considering the original ratio was 0.38?
💡 Hint: Consider how to maintain the balance between strength and shrinkage.
If upon testing, your actual flexural strength of a trial mix only reached 3.8 MPa, what remedial actions could you take in future designs?
💡 Hint: Reflect on improving the mix design adjustments.
