17. Introduction to Durability and Permeability
Durability and permeability of concrete play a crucial role in construction, affecting its longevity against environmental factors like freeze-thaw cycles, sulphate attacks, and marine conditions. Factors such as water-cement ratio and effective curing practices are vital for enhancing durability, while advanced materials and techniques can significantly improve concrete performance under aggressive environments.

What we have learnt
- Durability is essential for reducing long-term maintenance costs and ensuring structural integrity.
- Permeability influences the susceptibility of concrete to environmental attacks like freeze-thaw damage and sulphate corrosion.
- Utilizing supplementary cementitious materials can enhance concrete durability and resistance against degradation.
Key Concepts
- -- Durability
- The ability of a material to withstand environmental effects without significant deterioration.
- -- Permeability
- The rate at which fluids can pass through a material, critical for preventing harmful substance ingress.
- -- FreezeThaw Resistance
- The ability of concrete to withstand cycles of freezing and thawing without significant damage.
- -- Sulphate Attack
- Chemical degradation of concrete caused by the reaction of sulphate ions with hydrated cement compounds.
- -- Marine Durability
- The resilience of concrete structures against degradation in marine environments, involving chloride and sulphate attacks.
