In minerals, as a feldspar, it can be found as anorthite, an end-meer of the plagioclase series.. Uses. As a food additive, it is sometimes designated E556.It is known to the FDA as, at under 2% by weight, an anti-caking agent for table salt, and as an ingredient in vanilla

Effects of an experimental calcium aluminosilie cement

INTRODUCTION: Quick-setting calcium aluminosilie cement with improved washout resistance is a potential substitute for calcium silie cements in endodontics. This study examined the effect of an experimental calcium aluminosilie cement (Quick-Set; Primus Consulting, Bradenton, FL) on the viability of odontoblast-like cells.

Calcium Aluminate - an overview | ScienceDirect Topics

Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH, ranging from 11.4 to 12.5, is reduced as compared to OPC (Goñi et al., 1991 ). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.

The effect of CaO(MgO) on the structure and properties of

Oct 15, 2018· And in the calcium aluminosilie, the bond angle is about 138° and it is about 135° in magnesium aluminosilie. The bond angle of Si O Si is generally 140°, which is closer to that in calcium aluminosilie. This point shows that under the same mass content, the effect of MgO on the structure of aluminosilie is greater than that of CaO.
