If a concrete mix originally had a water-cement ratio of 0.40 and was changed to 0.55, how would you expect the performance to differ, especially in terms of structural applications?
💡 Hint: Consider how strength and ductility relate to this change.
Design a concrete mix targeting high durability in a marine environment. Discuss your choice of aggregates, water-cement ratios, and admixtures.
💡 Hint: Think about what properties are critical for marine applications.
