Abstract

It is becoming more generally accepted that the role of the polymers in these MDF (macro-defect-free) cement systems is more complex than simply acting as a processing aid or a filler. The polymer interacts in some way with the cations released from the cement to form a metal cross-linked polymer gel. Studies on complex formation in polymer gels have shown that there is often an unusual specificity in the ions, resulting in the highest degree of complexation. In addition, gel formation often occurs only within a narrow pH regime. Hence, the results shown here will attempt to examine the effects of altering the cement chemistry on strength development in calcium silicate-based systems.
