Standard Test Method for Potential Alkali Reactivity of Carbonate Rocks as Concrete Aggregates (Rock-Cylinder Method)
N C586
Annotation
This test method covers the determination of the expansion of a specimen of carbonate rock while immersed in a solution of sodium hydroxide (NaOH) at room temperature. 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.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
*A Summary of Changes section appears at the end of this standard.

Метод стандартной пробы для потенциальной щелочной реактивности скал карбоната как конкретные совокупности (рок-цилиндрический метод)
Этот метод тестирования покрывает определение расширения экземпляра скалы карбоната, в то время как погружено в решение гидроксида натрия (NaOH) при комнатной температуре. Изменения длины, происходящие во время такого погружения, указывают общий уровень реактивности скалы и должны ли тесты быть сделаны определить эффект агрегата, подготовленного от скалы на изменение объема в бетоне.
