Chemical admixtures can influence and modify nucleation and growth of minerals ( Griffin et al., 1999, Fricke et al., 2006 ). In the case of C 3 S and cement hydration, several studies have implied that chemical admixtures act on precipitation and growth of hydrates, interfering with them in various ways.

The results are provided in Table 1. The addition of 1.0 % SNF was required to reach the targeted slump flow. All tested PCE-based dispersants were much more effective, allowing for dosage reduction of 80 % and more. While PCE 1 resulted in a slight set-retardation of a few seconds, PCE 3 resulted in setting times comparable with SNF.

The effect of all superplasticizers is based on their adsorption to the positively charged cement particles, mostly to ettringite and monosulfate, via ionic groups (e.g. sulfonate or carboxylate) which also renders an excess of negative charge that induces an electrostatic repulsion between the particles resulting in better dispersion of the lat...
