Ultra-low hydration heat cementing material and preparation method thereof
The invention belongs to the technical field of cementitious material preparation, and particularly relates to an ultralow-hydration-heat cementitious material and a preparation method thereof. The ultralow-hydration-heat cementing material is prepared from the following raw materials in parts by weight: 1 to 5 parts of cement clinker, 12 to 46 parts of granulated blast-furnace slag in a fine-granularity interval, 16 to 20 parts of granulated blast-furnace slag in a medium-granularity interval, 18 to 51 parts of granulated blast-furnace slag in a coarse-granularity interval, 0 to 26 parts of graded fly ash and 15 parts of gypsum. According to the ultralow-hydration-heat cementing material provided by the invention, the main raw materials come from industrial waste residues, the energy consumption is low, the heat release is low, and the hydration temperature rise is lower than the decomposition temperature (less than 12 DEG C) of natural gas hydrate; on the basis of the close packing theory, particles with different particle sizes and raw materials with different proportions are reasonably used, the space structure is fully utilized, the structure is more compact, and therefore high strength is achieved. The cementing material has very important guiding significance on exploitation of natural gas hydrates.
本发明属于胶凝材料制备技术领域，具体涉及一种超低水化热胶凝材料及其制备方法。本发明超低水化热胶凝材料的原料按重量份数计，包括：水泥熟料1～5份，细粒度区间粒化高炉矿渣12～46份，中粒度区间粒化高炉矿渣16～20份，粗粒度区间粒化高炉矿渣18～51份，分级粉煤灰0～26份，石膏15份。本发明所提供的超低水化热胶凝材料，主要原材料来源于工业废渣，低能耗、放热低，其水化温升低于天然气水合物分解温度(＜12℃)；本发明以紧密堆积理论作为基础，合理使用不同粒度颗粒、不同占比原材料，空间结构得以充分利用，使得结构更致密，从而实现较高的强度。该胶凝材料对天然气水合物的开采具有十分重要的指导意义。
