A method for the production of Calcium sulphoaluminate Cements and cement produced with said method

摘要

The invention consists of a method for the production of cements based on calcium sulfoaluminate, and cement produced with said method, the method comprising the steps of forming a clinker by means of calcining raw materials higher than 1200 ° C in a manner that the clinker produced has a high content of calcium sulfoaluminate, tricalcium silicate and dicalcium silicate, and during or before the demolition stage, add the asiproduced clinker,and with the aforementioned basic components, optimal amounts of calcium oxide and hydroxide and calcium sulfate in order to activate said clinker. In said milling a temperature of approximately 100 ° C to 125 ° C must be observed, and a sufficient volume to convert the gypsum into homohydrate, so that the calcium sulfate present in the product thus obtained will be achieved, is able to react quickly during the hydration of the cement, resulting in the obtaining of etringite, requiring the presence of a superior pH 12.
