BS 8500-2:2015+A2:2019 PDF Download

BS 8500-2:2015+A2:2019 is a complementary British Standard to BS EN 206 and is part of a two-part series that provides specifications for constituent materials and concrete. It is intended for use by concrete producers, manufacturers, factory production control managers, commercial technical managers, concrete contractors, and specifiers.

The standard includes the latest options and testing procedures for constituent materials and concrete. It outlines requirements for the constituents of concrete, the properties of fresh and hardened concrete, the limitations for concrete composition, the specification of concrete, the delivery of fresh concrete, the production control procedures, and the conformity criteria and evaluation of conformity.

BS 8500-2 complements BS EN 206 by providing national provisions where required or permitted. It covers materials, methods of testing, and procedures that are outside the scope of BS EN 206 but within national experience.

The recent update to the standard expands the range of cementitious materials covered, including natural pozzolana, natural calcined pozzolana, high reactivity natural calcined pozzolana, Portland-pozzolana and pozzolanic cements, and ternary cements with up to 20% limestone fines. The update also provides clarity on the use of the equivalent concrete performance concept and offers additional guidance on the preparation and transport of cube specimens for strength testing.
