Test method Subject X586 It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Transport Research Laboratory Files: Alkali-reactivity can be detected in concrete, but the assessment of the importance and state of progress is almost impossible.

The xstm method is intended as a research and screening method rather than as the basis of a specification requirement. 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.

Sims, I Publication Date: 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.

Subscription pricing is determined by: The 29 common references are divided between the two articles. No other units of measurement are included in this 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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Reaction chem ; 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.

Figures; Photos; References; Pagination: Aggregates; Filing Info Accession Number: 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. This test method covers the determination of the expansive characteristics of carbonate rocks while immersed in a solution of sodium hydroxide NaOH at room temperature.

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.
