Significance and Use
This test method states various procedures that are recommended to quantify various aspects of the lime enhanced pozzolanic reaction. These tests are intended to qualify sources of fly ash and other pozzolans to meet specified job or project criteria as related to soil stabilization.
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.
