Hydraulic cement with an accelerated development of high strength

摘要: The invention consists in a method for the manufacture of calcium sulfoaluminate based cements, which formation clinker by burning raw materials at temperature above 1200 °C, so that produced has high content sulfoaluminate, tricalcium silicate and dicalcium silicate, and, during or prior to grinding resulting mixture, adding, together with basic components previously mentioned, optimum amounts oxide hydroxide sulfate as activate said clinker. During approximately between 100 125 °C shall be ensured, well sufficient time convert gypsum into hemihydrate, thus ensuring present product obtained will condition react rapidly hydration cement, etringite, requiring pH 12 order do this.
