Austroads Technical Specification ATS 5321 sets out the requirements for the application of maturity principles to determine the Strength - Maturity Relationship of a concrete mix (the “Maturity Method”) and apply it to production concrete. It may apply to either cast-in-place concrete or precast concrete.
The Contractor may use the Maturity Method for the purpose of facilitating early formwork removal, lifting of precast members or the early application of loading, subject to the Principal’s approval of the Quality Plan.
Edition 1.0 was superseded by Edition 1.1 in July 2025.
