Readerfast & Readerfast A
Readerfast and Readerfast A is a khaki/buff coloured calcium sulfo-aluminate for use in high-performance cement systems.
When used with a suitable source of sulphate and lime, Readerfast reacts to produce a composite cement combining the properties of rapid setting, high early strength development, good late strength, increased resistance to sulfate attack, and depending on the mix proportions, either shrinkage compensation or positive expansion.
The calcium sulphate content is invariably provided in the form of ground synthetic anhydrite and the lime is present in the Portland cement component.
The Readerfast range gives controlled set, enhanced strengths, shrinkage compensation/expansion and sulfate resistance. Uses include any cement based products needing these properties - for example:
- Patching compounds
- Floor screeds
- Tile adhesive and grouting
- Sprayed products
- Mortars and concrete
