- •
Efficiency factor k is often used as a practical approach for determination of the role of SCMs on concrete strength.
- •
The applicability of k-values to durability-related properties is questionable.
- •
Strength-derived k-values showed to be appropriate as a proxy-criterion only for carbonation resistance.
- •
Specific k-values are needed for chloride-resistance performance.
- •
These k-values were around 1.5 for fly ash and slag and lower than 1 for ground limestone and pozzolan.
