Determination of Calcium Ions in Hydrated Cement Paste at Early Stage

Abstract:

Article Preview

A novel method that allows determining instantaneous concentration of calcium ions, Ca2+, in hydrated cement paste (HCP) is suggested. EDTA solution (belonging to a group of carboxylic acids/carboxylates and borates) seems to be very effective retarder altering nucleation and subsequent growth of newly forming clusters of calcium minerals. Concentrations of Ca2+ have been determined for various water to cement ratios, at different times and for given temperature.
