Production method of cement substitute
The invention relates to a method for manufacturing a cement substitute, comprising the following steps: a) mixing a basic aluminosilicate-containing material with at least one aluminosilicate hydrate-containing material, b) heating the mixture thus obtained to a calcination temperature of less than 800 DEG C, thereby forming a calcined product, the calcined product includes a reactive amorphous phase having alkali metal ions incorporated therein. The method may further include the step of cooling the calcined product to a desired temperature. The invention also relates to a cement substitute obtainable by the method according to the invention. The cement substitute comprises a reactive amorphous phase of a co-calcined alkali metal aluminosilicate-containing material and an aluminosilicate hydrate-containing material having alkali metal ions bound therein. The alkali metal ion is preferably a sodium ion. The invention also relates to a cement composition containing the cement substitute according to the invention and to a mortar or concrete composition containing such a cement composition.
本发明涉及用于制造水泥替代品的方法，该方法包括以下步骤：a)将含碱性硅铝酸盐的材料与至少一种含硅铝酸盐水合物的材料混合，b)将由此获得的混合物加热至低于800℃的煅烧温度，从而形成煅烧产物，该煅烧产物包含具有结合在其中的碱金属离子的反应性无定形相。该方法可以进一步包括将煅烧产物冷却至期望温度的步骤。本发明还涉及通过根据本发明的方法可获得的水泥替代品。水泥替代品包含共煅烧的含碱金属硅铝酸盐的材料和含硅铝酸盐水合物的材料的反应性无定形相，其具有结合在其中的碱金属离子。碱金属离子优选是钠离子。本发明还涉及含有根据本发明的水泥替代品的水泥组合物和含有这种水泥组合物的砂浆或混凝土组合物。
