Natural hydraulic lime clinker and method for preparing early-strength hydraulic lime from natural hydraulic lime clinker
The invention discloses a natural hydraulic lime clinker which comprises the following mineral components: CaO, C2S, silicon magnesium calcium aluminate (6CaO. 4Al2O3. MgO. SiO2) and other mineral phases, and the natural hydraulic lime clinker is prepared by taking low-magnesium limestone, high-magnesium limestone, red sandstone and bauxite as raw materials and then carrying out high-temperature calcination. The high-magnesium low-grade limestone is used for firing the natural hydraulic lime clinker, and natural resources are fully utilized. The invention further provides a method for preparing the early-strength hydraulic lime from the natural hydraulic lime clinker, a hydration intermediate product of silicon magnesium calcium aluminate (6CaO. 4Al2O3. MgO. SiO2) in the natural hydraulic lime clinker is utilized to react with gypsum to generate hydrated calcium sulphoaluminate, and the early strength of a hydraulic lime cementing material is improved.
本发明公开了一种天然水硬性石灰熟料，包括矿物成分：CaO、C2S、硅镁铝酸钙(6CaO·4Al2O3·MgO·SiO2)和其他矿物相，所述天然水硬性石灰熟料以低镁石灰石、高镁石灰石、红砂岩、铝矾土为原料，再经高温煅烧而成。本发明利用高镁质低品位的石灰石烧成天然水硬性石灰熟料，充分利用自然资源。本发明还提供了一种天然水硬性石灰熟料制备早强水硬性石灰的方法，利用天然水硬性石灰熟中硅镁铝酸钙(6CaO·4Al2O3·MgO·SiO2)的水化中间产物与石膏反应生成水化硫铝酸钙，提高水硬性石灰胶凝材料的早期强度。
