SPACER STANDARDS

Reinforced concrete durability is only achieved by protecting the steel reinforcement from environmental attack. The level

of the protection depends not only upon the quality of the cover concrete but also upon the type and quality of the spacers

that are used. The focus of standards/ specification on improving concrete quality and durability has not been matched by

improved spacer requirements.

Eurocode 2 and the British Standard and AS/NZS standard have clearly specified rebar spacer strength and dimensional

tolerance and their adoption improves concrete performance. Reflecting the recognition of how concrete spacers can affect

concrete durability, standard/specification are now also including spacer durability properties that required them to match

or exceed those of the host concrete.

British Standard: Structural use of concrete — BS 8110-1:1997

Part 1: Code of practice for design and construction.

7.3 Fixing

The mix used for spacer blocks made from cement, sand and small aggregate should be comparable in strength, durability,

porosity and appearance to the surrounding concrete as far as is practicable. Concrete spacer blocks made on the

construction site should not be used.
