Supersession
This part of BS B500 supersedes BS 8500-2:2015A2:2019 which is withdrawn.
Relationship with other publications
BS EN 206:2013A2:2021. Together they form a plete package for the specification production BS 8500 contains additional United Kingdom provisions to be used in conjunction withand conformity of concrete.
BS 8500 is published in two parts:
•Part 1 Method of specifying and guidonce for the specifier andPart 2 Specification for constituent materials and concrete.
Information about this document
This new edition of BS 8500-2 incorporates technical changes only It does not represent a full reviewor revision of the document which will be undertaken in due course. The principal changes are:
• the inclusion of BS EN 197-5 cements and their equivalent binations as general purpose cements;• the redefinition of a production day for air content testing:clauses for production delivery and conformity requirements moved to a new normative annex;amendment of the bination conformity procedures for the new equivalent binations;corrections and minor clarifications; and
* all references have been updated.
The changes are predominantly concerned with the increased range of cementitious materialscovered. BS EN 197-5 introduced CEM II/C-M and CEM IV multi-ponent cements with a lower proportion of clinker than allowable by BS EN 197-1. The conformity procedure for binations and examples have been expanded for the equivalent binations of Portland posite andposite cements.
