A high-calcium hydrated lime at 90–94% Ca(OH)₂ — for lime:cement:sand mortars and renders, soil stabilisation, and water and flue-gas treatment. Non-hydraulic: it is used with cement in mortar, not instead of it.

Applications
Hydrated lime does two different jobs: it makes mortar workable and breathable, and it raises pH. Both matter, and they rarely sit in the same tender.
