| Background: The Portland cement is hydrophilic cement; as a result, the powder-to-liquid ratio affects the properties
of the final mix. In addition, the mixing technique affects hydration. The aim of this study was to evaluate
the effect of different mixing techniques (conventional, amalgamator and ultrasonic) on some selective physical
properties of Portland cement.
Material and Methods: The physical properties to be evaluated were determined using the ISO 6786:2001 specification.
One hundred sixty two samples of Portland cement were prepared for three mixing techniques for each
physical property (each 6 samples). Data were analyzed using descriptive statistics, one-way ANOVA and post hoc
Tukey tests. Statistical significance was set at P<0.05.
Results: The mixing technique had no significant effect on the compressive strength, film thickness and flow of
Portland cement (P>0.05). Dimensional changes (shrinkage), solubility and pH increased significantly by amalgamator
and ultrasonic mixing techniques (P<0.05). The ultrasonic technique significantly decreased working time,
and the amalgamator and ultrasonic techniques significantly decreased the setting time (P<0.05).
Conclusions: The mixing technique exerted no significant effect on the flow, film thickness and compressive strength
of Portland cement samples. |
