The effect of sodium carbonate (2%) on the hydration of tricalcium silicate was studied. Free lime, nonevaporable water content, calorimetric measurements, analysis of the liquid phase for Ca 2+ and OH − ions, zeta potential measurements, and compressive strength measurements were made. The accelerating action of sodium carbonate can be interpreted in terms of adsorption of ions. Further, since sodium carbonate is a structure breaker for water, more free water will be available in the presence of sodium carbonate, which may accelerate the reaction.
