Fig. 1.15 Adsorption isotherm of calcium lignosulfonate on ordinary Portland cement (Ernsberger). Fig. 1.15 Adsorption isotherm of calcium lignosulfonate on ordinary Portland cement (Ernsberger).
Water-reducing admixtures are not adsorbed equally by the various anhydrous and hydrated cement constituents and in studies with calcium lignosulfonate, the approximate maximum adsorption figures shown in Table 1.5 have been obtained [38,39], In addition, adsorption isotherms have been studied at various ages of C3A hydration [36] and it has been shown that it is the initial hydration products (less... [Pg.45]
