ABSTRACT
This specification pertains to quicklime and hydrated lime, either high calcium, dolomitic, or magnesium lime, for use in stabilization of soils. Quicklime and hydrated lime for soil stabilization shall conform to the required chemical composition for calcium, magnesium oxides, carbon dioxide, and free moisture. The physical properties of hydrated lime, quicklime, and residue of quicklime shall not exceed the specified limits. Chemical analysis of quicklime and hydrated lime shall be conducted.

The four types of lime under this specification shall be designated as Type N which is the normal hydrated lime for masonry purposes, type S which is the special hydrated lime for masonry purposes, type NA which is the normal air-entraining hydrated lime for masonry purposes and type SA which is the special air-entraining hydrated lime for masonry purposes. Hydrated lime for masonry purposes shall conform to the required chemical composition for calcium and magnesium oxides and carbon dioxide. The hydrated lime covered by Types N or S in this specification shall contain no additives for the purpose of entraining air.

The four types of lime under this specification shall be designated as Type N which is the normal hydrated lime for masonry purposes, type S which is the special hydrated lime for masonry purposes, type NA which is the normal air-entraining hydrated lime for masonry purposes and type SA which is the special air-entraining hydrated lime for masonry purposes. Hydrated lime for masonry purposes shall conform to the required chemical composition for calcium and magnesium oxides and carbon dioxide. The hydrated lime covered by Types N or S in this specification shall contain no additives for the purpose of entraining air.
SCOPE
1.1 This specification covers four types of hydrated lime.

Note 2—For normal (Type N) and special (Type S) finishing hydrated lime, refer to Specification C206.
Note 3—Some building codes prohibit the use of air-entraining materials in mortar, because of the accompanying reduction in bond and compressive strength.

1.1.1 PHL—Pozzolanic hydraulic lime for use in mortar, scratch, brown, and finish (stucco) coats of interior or exterior plaster.
1.1.2 PHLc—PHL with a maximum 20 % binder weight of hydraulic cement.
1.1.3 PHL-A—Air-entrained PHL.
1.1.4 PHLc-A—Air-entrained PHLc.
1.2 This specification classifies pozzolanic hydraulic lime by minimum hydrated lime content, maximum hydraulic cement content, and specific performance requirements.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Appropriate conversion can be done using IEEE/ASTM SI 10.
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.

ABSTRACT
This specification covers limestone suitable for use as dust in coal mines to prevent coal dust explosions. The limestone shall conform to the chemical composition requirements prescribed. The chemical analysis and the particle size analysis of the limestone shall be conducted.
SCOPE
1.1 This specification covers limestone suitable for use as dust in coal mines to prevent coal dust explosions.  
Note 1—Limestone can serve as a source of incombustible material in coal mine operations. Limestone is dusted onto coal exposures in sufficient amount so that not less than 65 % of all loose dust shall be limestone incombustible material. In return air courses the concentration of incombustible materials should be not less than 80 % of the total dust (MSHA 30 CFR 75.403). With such a concentration of limestone incombustible material, dust explosions cannot initiate or be propagated from nearby gas explosions. The limestone must be substantially dry in order to dust satisfactorily.
1.2 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.
1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

ABSTRACT
This specification covers limestone supplied for use as a mineral supplement in animal feeds. Limestone shall conform to the chemical requirements specified. In order to determine particle size, a sieve analysis shall be done.
SCOPE
1.1 This specification covers limestone supplied for use as a mineral supplement in animal feeds.  
Note 1—The calcium needed for animal nutrition is customarily supplied by limestone. Such limestone must be sufficiently fine to blend with mixed feeds and yet be free from excessive dusting.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.

ABSTRACT
This specification covers lime putty products made from hydrated lime or quicklime products. Lime putty is suitable for use in masonry, plaster and stucco applications. The hydrated lime or quicklime products used to make lime putty shall be tested and shall conform to the chemical composition, plasticity, residue, soaking period, popping and pitting, and density requirements specified.
