摘要

This paper documents laboratory testing and results showing that a new performance-based ASTM standard specification is appropriate for geopolymer concrete. The paper will provide recommended guidelines for the specification and limit the analysis to alkali-activated pozzolan cements, with no Portland cement. Specific performance-based specifications and supporting test data will be presented that characterize the minimum requirements for geopolymer concrete proposed for use in any construction application, without the need for the application of external heat. These performance specifications will include shrinkage, set-time, compressive strength, freeze and thaw resistance, chloride ion penetration resistance, sulfuric and hydrochloric acid attack resistance, elastic modulus, and Poisson's ratio. The specification does not include specific constituent detail, but is performance-based.
