PART 2 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. Expansion likely to occur in repeated wetting and drying conditions can also ashm underestimated.

Subscription pricing is determined by: The effectiveness of preventive measures such as the use of low-alkali cement and the addition of fly-ash and slag is difficult to assess.

This test method is intended to give a relatively rapid indication of the potential expansive reactivity of certain carbonate rocks that may be used as concrete aggregates. Sims, I Publication Date: 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 The inch-pound units in parentheses are provided for information only.

Specification standard ; 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.

No other units of measurement are included in this standard. This standard is also available to be included in Standards Subscriptions. Need more than one copy? 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.

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.
