Comparative Analysis of Selected Physicochemical Properties of Pozzolan Portland and MTA‐Based Cements

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
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
