Properties of Concrete for use in Eurocode 2. How to optimize the engineering properties of concrete in design to Eurocode 2

This publication is aimed at providing both civil and structural design engineers with a greater knowledge of concrete behaviour. This will enable the optimal use of the material aspects of concrete to be utilised in design. Guidance relates to the use of concrete properties for design to Eurocode 2 and the corresponding UK National Annex.

In the design of concrete structures, engineers have the flexibility to specify particular concrete type(s) to meet the specific performance requirements for the project. For instance where calculated defl ections exceed serviceability limits, the designer can achieve lower defl ections by increasing the class of concrete and the associated modulus of elasticity, rather than by resizing members. This publication will assist in designing concrete structures taylor-made for particular applications.
