Abstract
The need to reduce CO2 emissions stimulate the scientific community to develop an alternative to traditional Portland cement. Calcium sulfoaluminate cements, industrial production which first began in China in the 1970s, are currently being investigated as an alternative to this. The expansion of current knowledge about sulfoaluminate cements has been developed and implemented in a pilot mode, a new method for their preparation, according to which the sulfate formed by combustion of sulfur chemically reduced; This method will reduce the amount of CO2 emissions by 30% compared with Portland cement. Nevertheless, some of the compositions too quickly seize - perhaps due to the fact that the ettringite formed too quickly.
