Class C and Class F Fly Ash:Comparisons, Applications Unlike other emerging alternative supplementary materials that have no existing specification, natural pozzolans can be specified under ASTM C618 / AASHTO M 295 Transportation costs an issue in some cases needs to be weighed against rising costs for fly ash as supply becomes more difficult So Whats Up With Fly Ash?
The specification from AASHTO M295 is based on a previous ASTM C618 specification from 1996. Since that time ASTM C618 has been updated to the more recent version portrayed in this report. Transportation departments will often change their specification from the indicated ASTM C618 and AASHTO M295 to reflect regional practices and preferences. One
Fly Ash, Slag, Silica Fume, and Natural Pozzolans, Chapter 3ASTM C 618 (AASHTO M 295) Class F and Class C fly ashes are commonly used as pozzolanic admixtures for general purpose concrete (Fig. 3-4). Class F materials are generally low-calcium (less than 10% CaO) fly ashes with common. Supplementary cementitious materials are used in at least 60% of ready mixed concrete (2000PCA).
NCHRP - Transportation Research BoardProposed revision/update to the AASHTO M 295 standard specification or a new standard specification that addresses marginal or unconventional fly ash sources for use in highway concrete. 4. A draft TRNews article highlighting the products of this research and their implementation.
Comply with AASHTO M 295 for Class C and Class F. Comply with ASTM C618 for Class N. Alkali content calculated in accordance with DOTD TR 531 shall not exceed 2.5 percent by weight. Fly ash and natural pozzolans with alkali contents greater than 1.5 percent may only be used with innocuous (non-reactive) aggregates. 937
Summary Methods for Evaluating Fly Ash for Use in The current test for ASR mitigation contained in AASHTO M 295 (ASTM C441) uses PyrexÂ® glass as a synthetic alkali-silica reactive aggregate. For consistency with AASHTO PP 65, ASTM C1567 should be incorporated in AASHTO M 295 with a maximum expansion limit of 0.10% after 14 days of exposure in sodium hydroxide (NaOH) solution.
Use of Reclaimed Fly Ash in Highway Infrastructure Tech ASTM C618 and AASHTO M 295 are the most common fly ash specifications cited in highway construction contract documents. Both are constantly being reviewed and improved to ensure these standards are applicable to harvested ash as well as fresh ash, and improvements in testing are currently being discussed.
