Importance of using pozzolans in hydraulic and environmental structures

Q. Why is the use of an effective pozzolan particularly desirable in hydraulic, water treatment, environmental engineering structures, and in tunnel and canal linings?


A. The continuing presence of moisture in service ensures the maximum ultimate lime-pozzolan combination, and this enhances the properties and benefits previously mentioned, especially reducing the permeability.
