ASTM C1709 − 11 Standard Guide for Evaluation of Alternative Supplementary Cementitious Materials ASCM for Use in Concrete

Scope

1.1 This Guide is intended to provide a technical approach to the evaluation of alternative supplementary cementitious materials such as pozzolans and hydraulic materials that fall outside the scope of Specifications C618, C989, and C1240.

This Guide provides the initial steps for a comprehensive evaluation of an ASCM that provides due diligence for its specific intended uses in concrete; however, it does not evaluate conformance to all possible performance criteria for all types of concrete mixtures.

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 Performing the tests or meeting the test limits in this guide should not imply that the material tested meets the requirements of Specifications C618, C989, and C1240.

These materials should not be represented as such and each specific source is to be evaluated separately.

Significance and Use

4.1 Common types of SCM include fly ash, slag cement, calcined clays, and silica fume.

The introduction and widespread use of fly ash, slag cement, calcined clay, and silica fume have been characterized and supported by significant research and development programs, preconstruction testing, field testing and long-term performance monitoring.
