Standards Development
This part of BS 8500 specifies constituent materials and concrete, and complements BS EN 206-1:2026 and BS EN 206-2:2026. It provides United Kingdom national provisions where required or permitted by BS EN 206. It also covers materials, methods of testing and procedures that are outside the scope of BS EN 206, but within national experience. It gives guidance as to how the mixing of cements and additions in the mixer can be assessed to be classed as combination equivalents to factory produced cements.
BS EN 206-1:2026 and BS EN 206-2:206 have been published but without the complementary requirements and guidance required for national implementation. References need to ne updated, as does terminology to align with the new European standard.
BS EN 197-6 was published after the last revision to BS 8500-1 (2023) and describes CEM II/C-M cements utilizing building waste that will allow lower carbon concretes to be produced with recycled concrete fines and improve the quality of crushed concrete aggregates.
There has been requests from industry for the inclusion of CEM II/C-M (Q-L) cements (lower carbon ternary cements with calcined clays and limestone fines).
