1.1 These test methods cover physical testing of quicklime and hydrated lime, and of limestone not otherwise covered in ASTM standards.

Note 1-Quicklime and hydrated lime have a high affinity for moisture and carbon dioxide. Caution should be taken to protect both hydrated and quicklime during sampling, storage, and testing (see Practice C50).

1.2 The test procedures appear in the following order:

Section Air Entrainment 13 Apparent Loose Density of Hydrated Lime, Pulverized Quicklime, and Limestone 17 Apparent Packed Density of Hydrated Lime, Pulverized Quicklime, and Limestone 18 Autoclave Expansion of Hydrated Lime 8 Dry Brightness of Pulverized Limestone 16 Dry Screening by Air Jet Sieve 20 Fineness of Pulverized Quicklime and Hydrated Lime by Air Permeability 19 Limestone Grindability 21 Particle Size of Pulverized Limestone 15 pH of Pulverized Limestone 14 Plasticity of Lime Putty 7 Popping and Pitting of Hydrated Lime 9 Residue and Sieve Analysis 5 Settling Rate of Hydrated Lime 11 Slaking Rate of Quicklime 12 Specific Gravity of Hydrated Lime Products 22 Standard Consistency of Lime Putty 6 Water Retention of Hydrated Lime 10

1.3 The values stated in SI units are to be regarded as the standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
