Expansion likely to occur in repeated wetting and drying conditions can also be underestimated. Two types of alkali reactivity of aggregates are recognized: This standard is not included in any packages. The author investigates the mortar bar test described in ASTM C showing that it can give misleading results, as some rocks such as metamorphic quartz and some carbonates exhibit slow but progressive expansion.

Reaction chem ; The length changes occurring during such immersion indicate the general level of reactivity of rocks and whether tests should be made to determine the effect of aggregate prepared from the rocks upon the volume change in concrete. If the document is revised or amended, you will be notified by email. The test method is c5866 as a research and screening method rather than as the basis of a specification requirement.
