Anotace textu normy ASTM C977-18 :
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.

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 1: Quicklime 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
improve load-bearing properties and subsequently the lime-treated
soil hardens by chemical reaction.
Note 2: No attempt is made to present requirements for
by-product lime, commercial lime slurry, and so forth.
Specification requirements for these materials could be better
determined on a local basis.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
