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 particle size of hydrated lime shall be determined in accordance with the sieve analysis of hydrated lime in the referenced standard test method.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification pertains to quicklime and hydrated lime, either high calcium, dolomitic, or magnesian lime, for use in stabilization of soils (See Note 2).

Note 1Quicklime and hydrated lime act upon clay soils and may render such soils suitable for highway construction and for other load-bearing applications. In most cases, lime causes finely divided clay particles to agglomerate into coarser particles which improves load-bearing properties and subsequently the lime-treated soil hardens by chemical reaction.

Note 2No attempt is made to present requirements for by-product lime, commercial lime slurry, etc. Specification requirements for these materials could be better determined on a local basis.

1.2 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.

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.
