ABSTRACT:
A method of preparing magnesium oxychloride and/or oxysulfate cements is described which involves the control of temperature of the magnesium chloride and/or sulfate solutions and the magnesium oxide used to prepare the cements during mixing and the controlled addition of the requisite amounts of magnesium oxide, magnesium chloride and/or sulfate required to form the cements during the mixing procedure. In mixing the requisite oxides with the sulfate and/or chloride solutions used to produce the cement mixtures, the oxide is mixed and thoroughly blended with at least 80 percent of the requisite chloride and/or sulfate solution required to provide a homogeneous mixture. After achieving the initial homogeneous mixture, the balance of the chloride and/or sulfate solution required to provide the requisite chemical constituents to form an oxychloride or oxysulfate cement is added and thoroughly blended to provide a second homogeneous mixture capable of forming a magnesium oxychloride or magnesium oxysulfate cement product upon setting.
