Buyer’s Notes
Choosing the grade. Grade is by Ca(OH)2 content: this lot is about 90.3%. Higher purity gives more alkalinity per kg; buyers for water treatment compare available lime and residue, buyers for plastering look at fineness.
What to check on the spec sheet. Ca(OH)2, available CaO (68.2%), moisture, residue on the 250 BSS sieve, acid-insoluble and MgO. Fineness controls how fast it reacts and how much sludge forms.
Handling and storage. Irritating to eyes, skin and lungs. Keep sealed and dry, because it slowly picks up moisture and CO2 from the air and loses strength. Add to water slowly.
Where it is used. pH correction, flue-gas desulphurisation, soil stabilisation, and plastering and construction.
