“The European Guidelines for Self Compacting Concrete” represent a state of the art document addressed to those specifiers, designers, purchasers , producers and users who wish to enhance their expertise and use of SCC.
The Guidelines have been prepared using the wide range of the experience and knowledge available to the European Project Group. The proposed specifications and related test methods for ready-mixed and site mixed concrete, are presented in a pre-normative format, intend to facilitate standardisation at European level. This approach should encourage increased acceptance and utilisation of SCC.
“The European Guidelines for Self Compacting Concrete” define SCC and many of the technical terms used to describe its properties and use. They also provide information on standards related to testing and to associated constituent materials used in the production of SCC.
Durability and other engineering properties of hardened concrete are covered to provide reassurance to designers on compliance of SCC with EN 1992-1-1 Design of concrete structures (Eurocode 2).
The Guidelines cover information that is common to SCC for the ready-mixed, site mixed and the precast concrete industry. Chapter 12 is devoted to the specific requirements of precast concrete products.
The document describes the properties of SCC in its fresh and hardened state, and gives advice to the purchaser of ready-mixed and site mixed concrete on how SCC should be specified in relation to the current European standard for structural concrete, EN 206-1. It also describes the test methods used to support this specification. The appended specification and test methods are presented in a pre-normative format that mirrors current EN concrete standards.
Advice is given to the producer on constituent materials, their control and interaction. Because there are a number of different approaches to the design of SCC mixes, no specific method is recommended, but a comprehensive list of papers describing different methods of mix design is provided.
Advice is given to the contractor/user of ready-mixed and site mixed concrete on delivery and placing. Whilst accepting that SCC is a product used by both the precast and in-situ industries, the Guidelines attempt to give specific advice related to the differing requirements of the two sectors. For example, early setting and early strength are important to precasters, whereas workability retention may be more important in in-situ applications.
