✦ Synopsis

There is considerable current interest (1-4) in magnesia-phosphate cements (MPC), which develop strength rapidly and seem to be ideally suited for repair work.

At least three related systems are under investigation, which all involve an acid base reaction between MgO and some compound(s) containing ammonium and phosphate ions, viz. diammonium phosphate (DAP) (i), ammonium polyphosphate (APP) (2), or a mixture of monoammonium hydrogen phosphate (MAP) and sodium tripolyphosphate (STPP) (3,4).

Similar systems are of interest as dental cements (5-7). Some of our observations (4,8) differ from those reported by Sugama and Kukacka (1,2).

In our experiments, mortar samples were exposed to a CO2-enriched atmosphere (CO2-series) and to a CO 2 + SO2-enriched atmosphere (SO2-series). Because of the gas concentrations (0.7 vol.-% CO2; 0.06 vol.-% CO2) used, the dominant process consists in the reaction of CO 2 with the alkaline components

Drs Matusinovi~ and Curlin have undertaken a very useful investigation of the acceleration of setting in calcium aluminate cement CAC (high alumina cement HAC) by lithium salts (1). They have investigated the reasons why U + ions have a much greater influence in accelerating the setting time than th
