This Malaysian Standard describes the methods of specifying concrete and gives guidance for the specifier.
NOTE. The guidance for the specifier is given in Annex A. This annex provides guidance on the concrete quality to specify for selected exposure classes, intended working life and nominal cover to normal reinforcement. It does not give guidance on stainless steel and non-metallic reinforcement. Guidance on nominal cover to reinforcement for structural and fire consideration is available in other publications, e.g. structural design codes of practice.
This MS 523: Part 2 complements MS 523: Part 1. It provides Malaysia national provisions
where required or permitted by MS 523: Part 1. It also covers materials, methods of testing
and procedures that are outside the scope of MS 523: Part 1, but within national experience.
