These test methods cover physical testing of quicklime, hydrated lime, and limestone. Plastic property testing shall include test methods for standard consistency and plasticity of lime putty, water retention of hydrated lime, and air entrainment. Soundness testing shall include test methods for autoclave expansion, and popping and pitting of hydrated lime. Application testing shall include test methods for slaking rate of quicklime, dry brightness of pulverized limestone, limestone grindability determination by the laboratory ball mill method, and settling rate of hydrated lime. Particle size analysis shall include test methods for residue and sieve analysis, fineness of pulverized quicklime and hydrated lime by air permeability, particle size of pulverized limestone, and dry screening of hydrated lime, pulverized quicklime, and limestone by air jet sieving. Density measurement shall include the following test methods: apparent loose density, and apparent packed density of hydrated lime, pulverized quicklime, and limestone; specific gravity of hydrated lime products; and wet sieve analysis of agricultural liming materials.

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:
