Abstract

This specification covers the qualification of fly ash and other pozzolans for use with lime in plastic, nonplastic mixtures and other mixtures that affect lime pozzolanic reaction required by soil stabilization. Evaluation of pozzolans containing available lime, such as Class C fly ash, is given consideration. Pozzolans covered include artificial pozzolans such as fly ash, and natural pozzolans, such as diatomite and pumicite, in either raw or calcined state. Various procedures are recommended to quantify various aspects of the lime enhanced pozzolanic reaction. The tests shall qualify sources of fly ash and other pozzolans to meet specified job or project criteria as related to soil stabilization. The following shall be peformed on the pozzolan: water-soluble fraction, fineness, and lime-pozzolan strength development. For the nonplastic mixtures, compressive strength development and freeze-thaw resistance tests shall be performed. The materials shall be subjected to vacuum saturation strength testing.

Scope

1.1 This specification covers the qualification of fly ash and other pozzolans for use with lime in plastic, nonplastic mixtures and other mixtures that affect lime pozzolanic reaction required by soil stabilization. Evaluation of pozzolans containing available lime, such as Class C fly ash, is given consideration. Pozzolans covered include artificial pozzolans such as fly ash, and natural pozzolans, such as diatomite and pumicite, in either raw or calcined state.

1.2 The following precautionary caveat pertains only to the test method portion, Sections 5 and 10 of this specification: 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.
