Challenge Problems

Push your limits with challenges.

Question 1

During a project in hot weather, the concrete mix was found to lose workability quickly. Discuss strategies to maintain workability without compromising strength.

💡 Hint: Think about both temperature control and mix adjustments.

Question 2

Your construction project requires a concrete mix with high workability to fit into intricate molds. Which admixtures would you choose, and how would you determine the optimal water-cement ratio?

💡 Hint: Consider both the dynamic measure of workability and the physical characteristics of strength.
