significance And Use:
Excess soluble sulfate ions in hardened cement can result in reduced durability. This test method is intended to show whether calcium sulfate has been used in cement in such amount to leave excess... View More
scope:
1.1 This test method covers the measurement of water-extractable SO3 in hardened hydraulic cement mortar. This measurement is assumed to represent unreacted, available sulfate remaining in the mortar.
1.1.1 Warning-Fresh hydraulic cementious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
