The method of mixing will also be specified, as well as conditions that it may be used in.This allows a user of the concrete to be confident that the structure will perform properly.

Stamped concrete is an architectural concrete which has a superior surface finish. The choice of a concrete mix depends on the need of the project both in terms of strength and appearance and in relation to local legislation and building codes.The design begins by determining the requirements of the concrete.Such software provides the user an opportunity to select their preferred method of mix design and enter the material data to arrive at proper mix designs. Regular Roman concrete for example was made from volcanic ash (pozzolana), and hydrated lime.Roman concrete was superior to other concrete recipes (for example, those consisting of only sand and lime) used by other nations.Ongoing research into UHPC failure via tensile and shear failure is being conducted by multiple government agencies and universities around the world.

Micro-reinforced ultra-high-performance concrete is the next generation of UHPC.

Various types of concrete have been developed for specialist application and have become known by these names.

Concrete mixes can also be designed using software programs.

Regular concrete can typically withstand a pressure from about 10 MPa (1450 psi) to 40 MPa (5800 psi), with lighter duty uses such as blinding concrete having a much lower MPa rating than structural concrete.

Many types of pre-mixed concrete are available which include powdered cement mixed with an aggregate, needing only water.

In the UK, BS EN 206-1 defines High strength concrete as concrete with a compressive strength class higher than C50/60.
