Properties and application of chemical synthesized calcium aluminate cement |
| |
| Abstract: | The properties of chemical synthesized calcium aluminate cement such as strength development,setting time,bonded water content and exothermic profile were researched,and in comparison with conventionally sintered calcium aluminates cement,its application in the typical castable was also studied.Test results revealed that the strength development based on the chemical synthesized calcium aluminate cement was quick and substantial,early curing strength was high.Hydraulic exothermal profile showed that exothermal rate was in peak at about 2 hours;heat release was fast and concentrated.Bonded water content test also showed that the cement had high hydraulic reactivity.The typical castables prepared with chemical synthesized calcium aluminate cement performed a higher strength after dry,other properties like strength after firing were rather comparative with that containing conventional sintered calcium aluminate cement. |
