Performance-based Durability Specifications of Fly Ash Concrete for Chloride-induced Environment

Existing standard concrete practices under implementation of Standard Specifications for Building Works (SSBW) promptly altered from prescriptive specifications to Performance-based Durability Specifications (PBDS) as advocated by Eurocode 2. This study was carried out to overcome the chloride-induc...
