The UK Concrete Standard BS 5328 was withdrawn in December 2003. This guide, published by Tarmac, gives a very useful assessment of the impact of the changes to the previous Standard which is being replaced by two Standards, a European Standard (BS EN 206-1: Concrete – Part 1) and a complementary British one (BS 8500 Concrete).
The guide covers the following aspects:
• Workability (now termed consistence), strength and air content
• Density requirements for normal and heavy-weight concrete
• Chloride classes
- Changes in terminology and designations for concrete types
• Sulphate and aggressive ground conditions
• Slump tests and classes
The reader is advised that both the European Standard and the complementary British Standard need to be used.
