4.2 Sub-famIlies of air lime
4.2.1 Calcium lime (CL)
Calcium lime is an air lime consisting mainly of calcium oxide and/or calcium hydroxide without any hydraulic or pozzolanic addition.
4.2.2 Dolomitic lime (DL)
Dolomitic lime Is an air lime consisting mainly of calcium magnesium oxide and/or calcium magnesium hydroxide without any hydraulic or pozzolanic addition.
4.3 Forms of air lime
4.3.1 QuIcklime (Q)
Quicklime is an air lime mainly in the oxide form which reacts exothermically on contact with water. Quicklime is available in a range of sizes from lump to powder.
4.3.2 Hydrated lime (S, S PL or S ML)
Hydrated lime is an air lime mainly in the hydroxide form produced by the controlled slaking of quicklime. Hydrated lime is available as:
— powder(S);
— putty (S PL): or
— slurry or milk of lime (S ML).
Dolomitic lime is also produced as semi-hydrated dolomitic lime (Si). mainly consisting of calcium hydroxide and magnesium oxide.
4.4 Calcium lime
4.4.1 Classification of calcium lime
Calcium lime shall be classified according to the notation given in Table 1 and its total (CaO + MgO) content in accordance with Table 2.
Conformity with this classification is assessed by means of statistical quality control as described in Annex A
of this European Standard.
4.4.2 Chemical requirements for calcium lime
The properties of the type of calcium lime shown in Table 2 determined in accordance with EN 459-2 shall conform to the requirements in that table. All types of calcium lime listed in Table 2 may contain additives in small quantities to improve the manufacture or properties of calcium lime. When the total content exceeds 0,1 %, the actual types and amounts shall be declared.
4.4.3 Physical requirements and other physical properties for quicklime The physical properties of the type of quicklime shown in Table 3 and Table 4 determined in accordance with EN 459-2 shall conform to the requirements in those tables.BS EN 459-1 pdf download.
