ASTM C110-20 PDF Download

The ASTM C110-20 standard provides guidance on conducting physical tests on these materials. The standard addresses various aspects of physical testing, including plastic property testing, soundness testing, application testing, particle size analysis, and density measurement.

Plastic property testing involves determining the standard consistency and plasticity of lime putty, as well as water retention and air entrainment of hydrated lime. Soundness testing examines the autoclave expansion, popping, and pitting of hydrated lime. Application testing focuses on evaluating the slaking rate of quicklime, the dry brightness of pulverized limestone, the grindability of limestone using the laboratory ball mill method, and the settling rate of hydrated lime. Particle size analysis includes residue and sieve analysis, determination of fineness using air permeability for pulverized quicklime and hydrated lime, measurement of particle size for pulverized limestone, and dry screening using air jet sieving for hydrated lime, pulverized quicklime, and limestone. Density measurement involves determining apparent loose and packed density for hydrated lime, pulverized quicklime, and limestone, as well as specific gravity of hydrated lime products and wet sieve analysis of agricultural liming materials.

The standard also includes important cautionary notes regarding the high affinity of quicklime and hydrated lime for moisture and carbon dioxide. It emphasizes the need to protect these materials during sampling, storage, and testing. The test methods are organized in a logical order within the standard, making it easy for users to follow the prescribed procedures.
