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)

Importancia y uso:

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.
