High early and long term strength concrete

Concrete can be specifically designed to have higher early strengths or higher long-term strengths depending on the construction application.

For high early strength concretes, compressive strengths are developed more rapidly (not to be confused with lower setting time). These materials may ideally suit applications such as precast concrete or situations where early age strength for stripping of formwork is required.

Higher long-term concrete strengths may be required for applications such as some building column bases or large foundations. In such cases, mixes can be designed such that potential conflicting design and constructional requirements are optimised.
