Figure 7
Calculated density–time plots obtained by the method outlined in the text for five cases involving synthetic tricalcium silicate hydration: the pure control system (ref) and four additions of polynapthalene sulphonate (1% PNS; 1% PNS plus a further 0.64% NaOH; 1% PNS plus a further 1.14% Na₂SO₄; 1% PNS plus a deliberately delayed addition of PNS by 45 minutes). After an initial density rise over the first 1–2 h, the density plots show very differing characteristics.
