What is permeability in concrete?
Think about how fluids move through materials.
Why do we want lower permeability?
Consider the long-term effects on structures.
What is the primary reason for reducing permeability in concrete?
Think about what moisture can do to concrete.
True or False: Using a higher water-cement ratio generally reduces concrete strength.
Consider how water affects concrete density.
Discuss how a lower water-cement ratio and the inclusion of SCMs would work together to minimize permeability in concrete structures.
Consider their combined effects on both hydration and density.
Evaluate the impact of improper curing on the permeability of concrete, and suggest measures to mitigate these effects.
Think about the importance of hydration for concrete strength.
