Effects of Formulation Components on Properties
1. Viscosity: Finer sized filler produced higher viscosity than coarser sized filler.
2. Tensile Strength: The tensile strength can be increased by:
a. Increasing the ratio of dry premix to aqueous phase;
b. Increasing the concentration of the cement component.
3. Elongation: The elongation can be increased by:
a. reducing the ratio of dry premix to aqueous phase;
4. Water Proofing: increasing the amount of NALSTANEÒ M will impart better waterproofing to the membrane.
