Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A concrete structure was built with a water-cement ratio of 0.55 in a coastal area. Discuss the potential long-term impacts on the structure's integrity.

💡 Hint: Focus on the chemical interactions that might occur due to excessive water.

Challenge 2 Hard

How would you approach redesigning a mix that initially had a water-cement ratio of 0.50 for a bridge in a sulfate-rich environment?

💡 Hint: Consider strategies for improving workability without increasing the w/c ratio.
