This British Standard specifies terms, definitions and requirements for special purpose admixtures in order to establish suitability for use in concrete conforming to BS EN 206-1.
The admixtures covered are listed as follows; they are intended for use in plain, reinforced, foamed, prestressed and semi-dry concrete as appropriate. The concrete can be site mixed, ready mixed or pre-cast:
— underwater concrete admixtures;
— shrinkage reducing admixtures;
— corrosion inhibiting admixtures;
— pumping aids;
— segregation reducing admixtures;
— foaming admixtures;
— semi-dry concrete admixtures.
Provisions governing the practical application of admixtures in the production of concrete, i.e.
requirements concerning composition, mixing, placing, curing, etc. of concrete containing admixtures are not within the scope of this standard.
