What is PD CEN/TR 16349 - Avoidance of a damaging ASR in concrete about?
PD CEN/TR 16349 is a technical report that gives guidance for avoiding a damaging Alkali-Silica Reaction (ASR) in concrete.
Who is PD CEN/TR 16349 - Avoidance of a damaging ASR in concrete for?
PD CEN/TR 16349 on ASR in concrete is useful for:
- Manufacturers of concrete and concrete products
- Cement and concrete industry
- Civil engineers
- Contractors
- Quality control and testing bodies
Why should you use PD CEN/TR 16349 - Avoidance of a damaging ASR in concrete?
ASR in concrete is a result of the reaction between the alkaline pore solution in concrete and reactive mineral species (as reactive silica and silicates) in the aggregate. ASR is a damaging mechanism in concrete that causes cracking and deterioration of the concrete.
In this regard, PD CEN/TR 16349 covers the elements of specifications for avoiding a damaging ASR in concrete within the following structure:
- Characterisation of the environment
- Undertaking recommendations for precautionary measures appropriate to concrete, depending on the environmental category
PD CEN/TR 16349 specifies the levels of characterisation of the environment, precautionary measures appropriate to concrete and verification of the suitability of a concrete mix.
Thus, if you are a manufacturer of concrete, PD CEN/TR 16349 can guide you on the specifications to avoid ASR in order to investigate the expansion and cracking behaviour of concrete.
Moreover, this assessment enables manufacturers to reconsider the choice of materials such that the overall performance and cement can be maintained.
