• Số trang / Page: 23
• Phạm vi áp dụng / Scope of standard: 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 C 50). 1.2 The test procedures appear in the following order: Section Air Entrainment 8Apparent Loose Density of Hydrated Lime, Pulverized Quicklime, and Limestone 20Apparent Packed Density of Hydrated Lime, Pulverized Quicklime, and Limestone 21Autoclave Expansion of Hydrated Lime 9Dry Brightness of Pulverized Limestone 12Dry Screening by Air Jet Sieve 18Fineness of Pulverized Quicklime and Hydrated Lime by Air Permeability 16Limestone Grindability 13Particle Size of Pulverized Limestone 17Plasticity of Lime Putty 6Popping and Pitting of Hydrated Lime 10Residue and Sieve Analysis 15Settling Rate of Hydrated Lime14Slaking Rate of Quicklime 11Specific Gravity of Hydrated Lime Products22Standard Consistency of Lime Putty 5Water Retention of Hydrated Lime 7Wet Sieve Analysis of Agricultural Liming Materials191.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.
