Early-strength special cementing material and preparation method thereof
The invention provides an early-strength special cementing material and a preparation method thereof. Raw materials used in the invention are limestone, clay, iron powder, apatite, bauxite, fly ash, mineral powder, gypsum and silica fume which widely exist in the nature, a firing temperature is low, and the emission of carbon dioxide is less. The early-strength special cementing material provided by the invention can be used for reducing the consumption of limestone resources and improving the mechanical property and durability of a traditional silicate cementing material; and compared with an existing cementing material, the early-strength special cementing material prepared by the invention has the characteristics of quick hardening, early strength, a high sulfate erosion resistance coefficient and strong chloride ion infiltration resistance, and has wide market application prospects.
本发明的提供一种早强型特种胶凝材料及其制备方法，所用的各原料为自然界广泛存在的石灰石、粘土、铁粉、磷灰石、铝矾土、粉煤灰、矿粉、石膏和硅灰，烧成温度低，并且二氧化碳排放少。本发明提供的早强型特种胶凝材料可用于解决减少石灰石资源的消耗、改善传统硅酸盐胶凝材料的力学性能和耐久性能，与现有的胶凝材料相比，本发明制备的早强型特种胶凝材料，具有快硬早强，抗硫酸盐侵蚀系数高、抗氯离子渗透能力强的特点，具有广阔的市场应用前景。
