Reaction chem ; Specification standard ; Alkali-reactivity can be detected in concrete, qstm the assessment of the importance and state of progress is almost impossible. As the significance of the mortar bar test results depend upon the conditions tested, it is relevant to employ the cement type and aggregate proposed for actual use. 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 awtm carbonates exhibit slow but progressive expansion.

It is intended to supplement data from field service records, petrographic examinations according to Guide Cand tests of aggregate in concrete according to Test Method C Please asym verify your email before subscribing to alerts.

The length changes occurring during such immersion indicate the general level of reactivity of the rock and whether tests should be made to determine the effect of aggregate prepared from the rock upon the volume change in concrete.

The test method is intended as a research and screening method rather than as the basis of a specification requirement. Alkalies participating in the expansive reactions with aggregate constituents in concrete usually are derived from the hydraulic cement; under certain circumstances they may be derived from other constituents of concrete or from external sources.

Two types of alkali reactivity of aggregates are recognized: The length changes occurring during such immersion indicate the general level of reactivity of the rock and whether tests should be made to determine the effect of aggregate prepared from the rock upon the volume change in concrete.
