چکیده

Physicochemical properties of pozzolan Portland cement were compared to ProRoot MTA and MTA BIO. To test the pH, the samples were immersed in distilled water for different periods of time. After the pH analysis, the sample was retained in the plastic recipient, and the electrical conductivity of the solution was measured. The solubility and radiopacity properties were evaluated according to specification 57 of the American National Standard Institute/American Dental Association (ANSI/ADA). The statistical analyses were performed using ANOVA and Tukey's test at a 5% level of significance. Pozzolan Portland cement exhibited pH and electrical conductivity mean values similar to those of the MTA-based cements. The solubilities of all tested materials were in accordance with the ANSI/ADA standards. Only the MTA-based cements met the ANSI/ADA recommendations for radiopacity. It might be concluded that the pH and electrical conductivity of pozzolan Portland cement are similar to and comparable to those of MTA-based cements.

Relationship between Compressive and Chemical Compositions of Portland and Pozzolanic Cements

Pozzolans have been used to improve the some properties of concrete and also to reduce the cost of producing cement. Many researchers investigated pozzolanic cements, which were mostly made with kind of artificial or natural pozzolans. While the most recent investigations on pozzolan containing cements study the effect of pozzolan type, replacement amount and fineness, this study was investigat...
