(Practice)Standard Practice for Determination of Major and Minor Elements in Aqueous Pore Solutions of Cementitious Pastes by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)
Standard Practice for Determination of Major and Minor Elements in Aqueous Pore Solutions of Cementitious Pastes by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)
SIGNIFICANCE AND USE
5.1 The chemical composition of the liquid in cementitious pastes is an important indicator of the solid component reactivity at early times, being influenced by the content and rate of reaction of readily soluble alkali components, lime, and other soluble phases. Monitoring the solution composition with time can provide valuable diagnostic information about cement quality and reactivity to supplement other sources of characterization data. This practice is intended to aid in the interpretation of the concentrations of readily soluble components in cement paste solutions, which may include portland cement, limestone, fly ash, ground granulated blast furnace slag, or other components. It provides guidance for measuring the time dependence of the concentrations of one or more components, on an elemental basis, including, but not limited to, aluminum, calcium, potassium, silicon, sodium, and sulfur.
SCOPE
1.1 This practice describes a procedure for collection, sample preparation and analysis of aqueous pore solutions obtained from cementitious materials at different hydration times when analyzed by ICP-OES for the six most common readily soluble elements aluminum, calcium, potassium, silicon, sodium and sulfur.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
