Standard Test Method for Water-Extractable Sulfate in Hydrated Hydraulic Cement Mortar
N C265
Annotation
This test method covers the measurement of waterextractable SO3 in hardened hydraulic cement mortar. This measurement is assumed to represent unreacted, available sulfate remaining in the mortar.
Warning—Fresh hydraulic cementious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
Values in SI units were obtained by measurement in SI units or by appropriate conversion using the Rules for Conversion and Rounding given in IEEE/ASTM SI-10 Standard of measurements made in other units.
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.
*A Summary of Changes section appears at the end of this standard.
Автоматический перевод:
Метод стандартной пробы для водно-извлекаемого сульфата в гидратируемом миномете гидравлического цемента
Этот метод испытаний покрывает измерение waterextractable SO3 в укрепленном гидравлическом цементном растворе. Это измерение, как предполагается, представляет не реагировавший, доступный сульфат, остающийся в миномете.
