“Special Class” is Concrete which is specified to have certain
properties or characteristics different from, or additional to, those of
Normal Class concrete.
Special Class requirements are either:
- Performance based and may specify a property which can be
verified through testing - such as compressive strength of 60MPa @ 28
- Prescription based and may specify the mix design by dictating the material types and proportions - such as 280
Performance and Prescription requirements may include such things as:
microstrain shrinkage, flexural or tensile strength, early age strength
limitation, non-chloride additives, maximum water cement ratios, GP or
GB cement types, fibres, mineral oxide pigments, water proofing
additives, testing requirements, pumping and placement requirements,
