Section D of the Standard Specification of Building Works 2014 do not underline the use of corrosion inhibitors. Table D4 of the specification only listed five types of admixtures only to be used. However, the use of corrosion inhibitors are normally being specified to maritime structures but not always. The general specification has guidance on the durability of a concrete mix by specifying the exposure classes and the related required cover, concrete grade and type of cement to be used. The use of corrosion inhibitors are additional option and can be added if required by the designer.
